School-aged children are vulnerable to nutritional deficiencies of fiber and vitamin C because they consume less vegetables and fruit. One effort to prevent fiber and vitamin C deficiency is by making ice cream products that contain high levels of fiber and vitamin C where the additional ingredients are obtained from brown rice bran and crystal guava. The aim of this experimentation is to decide the impact of red rice bran and crystal guava formulations on the quality of ice cream products including organoleptic properties, fiber content and vitamin C levels. The research design used was experimental in nature using a one factor complete randomized design with 3 formulations of brown rice bran and guava crystals namely F1 (15%:85%), F2 (25%:75%) and F3 (35%:65%). The research method used the hedonic test to determine the organoleptic properties, enzymatic gravimetry for the fiber test and iodimetri titration for the vitamin C test. Formula F1 (15%:85%) was the best formula that met the adequacy of vitamin C and daily vitamin C for elementary school children of 20% fiber and 80% in 1 serving (80 g). The Kruskall Wallis test revealed that there was an effect of different formulations of red rice bran and crystal guava ice cream on the color, taste and overall taste of the ice cream (p<0.05). The production cost of F1 ice cream is IDR 3,000/80 g.

Effect of crossbreeding and dietary neutral detergent fiber (NDF) levels on feed intake, nutrient digestibility, rumen parameters and nitrogen retention of beef cattle

This experiment sought to evaluate the influence of varying levels of neutral detergent fiber (NDF) in the diet on feed intake, nutrient digestibility, rumen conditions, and nitrogen retention in crossbred cattle. Beef cattle aged 18 months were organized into groups using a 2x (4x4) Latin square design. The NDF levels investigated were 47%, 51%, 55%, and 59% of dry matter (referred to as NDF47, NDF51, NDF55, and NDF59 treatments, respectively). While dry matter (DM) consumption per 100 kg body weight (BW) did not exhibit significant differences between treatments, Charolais crossbred cattle (2.16 kg DM) demonstrated higher intake than Black Angus crossbred cattle (2.04 kg DM). Metabolizable energy intake in Charolais crossbred cattle significantly differed from that in Black Angus crossbred cattle (17.6 and 16.7 MJ/100 kg BW, respectively). Regarding NDF treatments, NDF47 did not differ from NDF51 and NDF55, but it was significantly higher (P<0.05) than the NDF59 treatment (18.1, 17.3, 17.1, and 16.0 MJ/100 kg BW, respectively). Although dry matter and organic matter digestibility did not significantly differ between Charolais and Black Angus crossbred cattle, variations were noted among treatments (P<0.05). Specifically, DM digestibility of NDF47 (62.8%) was significantly higher than NDF59 (55.4%), with no significant differences observed for NDF51 (59.8%) and NDF55 treatments (58.9%). Rumen pH, N-NH3, and total volatile fatty acid concentrations at 0h and 3h post-feeding did not exhibit significant differences (P>0.05) in this study. However, nitrogen retention in Black Angus crossbred cattle was significantly lower than in Charolais crossbred cattle (0.124 and 0.166 g/kg BW, respectively). Across treatments, nitrogen retention values were numerically higher (P>0.05) in NDF47, NDF51, NDF55, and NDF59 treatments (0.166, 0.148, 0.139, and 0.126 g/kg BW, respectively). In summary, this study determined that Charolais crossbred cattle displayed increased feed intake, crude protein digestibility, and nitrogen retention compared to Black Angus crossbred cattle. Furthermore, a dietary NDF level of 55% was suggested as suitable for practical use in terms of feed utilization by farmers. Keywords: Forage, crossbreeding, rumen fermentation, and ruminant.

Incorporation of recovered food and food scraps into poultry feed: A systematic review

Abstract Food wastage represents the loss of both economic and resource investments. Incorporation of recovered food and food scraps, defined as the potentially edible organic matter left over from the preparation, sale, and consumption of food, into animal feed is a potential strategy to reduce food wastage and recover some of the embedded resources within the residual food material. There is a need to align recovered food and food scraps’ nutritional quality, chemical and biological safety with scalable and feasible processing requirements that dovetail with the nutritional requirements of food animals. This review examines the feasibility of incorporating treated post-consumer food scraps into poultry feed, which currently represent the most consumed animal protein on the planet. The review summarizes the broad nutritional composition of post-consumer food scraps, toxicological considerations associated with incorporating food scraps into poultry feed, food scrap pre-treatments related to feed applications and feeding studies that incorporated post-consumer food scraps into animal feed rations. Research appears to indicate that sterilization through heat treatment is sufficient to control pathogenic microorganism contamination in recovered food. Other contaminants such as mycotoxins, heavy metals, microplastics, biogenic amines, antinutritional factors cannot always be removed from recovered food and subsequently, infrastructure to survey levels of contamination in recovered food to be used in concert with developing technologies to better remove these contaminants is recommended. Subsequently, the review illustrates that pre-treatments in concert with surveillance of incoming recovered food and food scraps may be used to ensure the safety of incorporating such material into poultry feed. Studies show large variability in the nutritional composition of consumer food scraps, but on average, lipid and fiber levels are higher in recovered food scraps compared to maize and soybean meal, while protein levels are higher than in maize and lower than in soybean meal. Feeding studies suggest an incorporation level of up to approximately 20% is associated with positive or neutral impacts on growth performance indicators

Millets: The Nourishing Solution to Food Security Challenges Over Cereal-Based Cropping Systems

A heightened emphasis on augmenting millet production and accentuating their nutritional benefits is pivotal in mitigating reliance on conventional crops, fostering dietary diversity, and enhancing food security, particularly in times of natural calamities when food scarcity is prevalent. The United Nations General Assembly has designated the year 2023 as the International Year of Millet. Millets hailed as 'superfoods,' boast high levels of protein, fibre, vitamins, and minerals. India stands as a major contributor, producing 80% of Asia's millets and 20% globally, as reported by the Ministry of Agriculture and Farmers Welfare. Statistics reveal that over 90 million individuals in Africa and Asia incorporate millets into their diets, with Africa accounting for more than 55% of global production, followed by Asia at nearly 40%, while Europe constitutes approximately three per cent of the worldwide market. Specifically in India, West Bengal adheres to a predominantly monocultural cropping system, predominantly focused on rice. Monoculture systems are highly susceptible to blights and pests due to their lack of diversity, leading to reduced soil fertility and compromised soil structure. Cultivating millets not only offers a viable solution by diminishing reliance on synthetic fertilizers and pesticides but also facilitates a transition towards sustainable agriculture. This involves diversifying crop rotations and steering clear of the pitfalls associated with mono-cropping systems. Introducing various millet types into cropping systems can significantly enhance food security. Each millet variant possesses unique qualities that enable them to withstand extreme climatic conditions, making them particularly relevant as adaptive measures in the current context of global warming and climate change issues.

Water absorption of food wheat flour – comparison of direct and indirect methods

The study aims to compare three methods used for the evaluation of water absorption of wheat flour: a) a direct method consisting of a standard procedure on a Farinograph-E device and b) two indirect methods, namely NIR spectroscopy and centrifugation. Forty-four samples of Czech food wheat were collected from the harvest year 2021. Namely, 23 samples of food wheat from the standard maturity collection ‘SM2’ and 21 samples from the early maturity collection ‘EM2’. All wheat samples were ground to obtain wheat flour of fine granulation. The flour samples were characterised by protein and ash content of 10.55-14.75% and of 0,59-0.63%, respectively. The water absorption ranged from 55.7% to 63.2% flour weight (Farinograph standard procedure), 60.1-67.1% flour weight (NIR spectroscopy), and 67.6-77.2% flour weight (centrifugation). Based on the results obtained by ANOVA statistical analysis, no significant difference was found for all qualitative parameters of SM2 and EM2 (p = 95%). According to the mentioned methods for both indirect determinations of water absorption in the sets SM2 and EM2, the prediction of the standard farinograph water absorption was more accurate using the NIR technique (minimal and maximal pair differences of 1.01 and 6.86 percentage points, in contrast to 1.78 and 14.87 percentage points for the centrifugation method). Linear regression confirmed the primary importance of protein content for the water absorption values. Also, the ash content should be considered because it reflects the dietary fibre level, and the fibre influences the water absorption values as well.

Assessment of worst-case potential airborne asbestos exposure associated with the use of cosmetic talc: application of an exponential decay model.

Talc is used in cosmetic products to confer desirable properties, such as moisture absorption and smooth texture, to the finished products. Concerns have been raised about the potential presence of asbestos in products containing cosmetic talc. Reconstruction of potential asbestos exposure from the use of cosmetic talc products (assuming a trace level of asbestos) requires consideration of consumer use patterns. Although application generally only lasts seconds, exposure theoretically may continue if the consumer remains in the immediate vicinity. Most published exposure measurements have not adequately characterized the potential for continued exposure. In this analysis, estimates and measurements of airborne asbestos fiber concentrations associated with cosmetic talc use from 10 published studies were used as inputs to an exponential decay model to estimate "worst-case" exposure during and following application. The resulting geometric mean 30-min time-weighted average (TWA) concentrations were 0.006 f/cc for both puff and shaker application, for diapering, 0.0001f/cc (adult applying baby powder) and 0.0002 f/cc (infant), and for makeup application, 0.0005 f/cc. Application of an exponential decay model to measured or estimated asbestos concentrations associated with the use of cosmetic talc products yields a conservative means to comprehensively reconstruct such exposures. Moreover, our results support that, if a cosmetic talc powder product contained a trace level of asbestos fibers, the "worst-case" airborne asbestos exposure associated with its application is low.

Effect of cutting time and storage time on the nutritional value of stargrass hay

The objective of this study was to assess the effect of cutting time on the nutritional composition and dehydration rate of stargrass, as well as the nutritional value of the hay as a function of storage time. Two plant cutting times were analyzed: at 13:00 (H13) and 17:00 (H17). After cutting, the dehydration rate of both the plant and its fractions until baling was monitored. The bales were checked for nutritional composition and digestibility after 30, 60, 90 and 120 days. At the time of cutting, a difference was observed for the concentrations of ethanol-soluble carbohydrates, which were higher for H17 (90.3 g kg-1) compared to H13 (52.9 g kg-1). Leaf dehydration rates were higher in the H17 treatment. Cutting time had no influence on the nutritional value of the hay. With storage time, there was an increase in the levels of neutral detergent fiber and acid detergent fiber, and a reduction in the content of ethanol-soluble carbohydrates. It was concluded that cutting at 17:00 allows for a greater accumulation of soluble carbohydrates in the plant. Cutting time does not change the time required for dehydration and the nutritional value of the hay. Storage time reduces soluble components and increases fibrous constituents

Diet Therapy for Hypertension

One of the main health issues that the world faces is hypertension. Patients' quality of life and survival are significantly impacted by the related morbidity and mortality consequences. It has been demonstrated that enhancing blood pressure regulation improves general well-being. In addition to pharmacological therapy, non-drug approaches including nutrition modifications are crucial for blood pressure control as well. strain. Several research have been done on the impacts of alcohol, hard water, obesity, and small dietary reductions salt and increases in consumption of potassium, foods high in calcium, diets heavy in unsaturated fats and low in animal fats, and finally higher dietary fiber levels associated with obesity. Although a few of these, while certain minerals are clearly recommended, others are contentious and yet undergoing investigation. Patients are often counseled on dietary changes, which have a significant positive impact on blood pressure control. Consequently, an analysis of the available data will be highly beneficial in assisting patients' doctors or nutritionists in making decisions. This review paper examines the role of nutrition in the treatment of Hypertension that aimed to investigate the part that dietary variables played in hypertension both separately and in relation to eating patterns as a whole.

Physicomechanical and erosion wear characterization of PLA/Jute fiber biocomposite

Introduction: The present study has demonstrated the effect of short jute fiber on physical, mechanical and erosion wear performance of PLA based composite. Problem Statement: An attempt has been made to develop and investigate the environment friendly and biodegradable composites based on jute fiber and PLA composite. Materials and Method: The erosion wear performance was assessed on Air-jet erosion tester. The design of experiments was prepared as per Taguchi orthogonal array L16 under for different factors of impact velocity, impingement angle, erodent size and jute fiber fraction and level of each factor was kept four. ANOVA was applied to find the best significant factor affecting erosion rate of composite. Main Results: The finding of results indicated that the density significantly increased with the addition of jute fiber and in parallel, it indicated the increment in the void content. The mechanical properties like hardness, tensile strength, flexural strength, impact strength and fracture toughness of PLA based composite reinforced with 15 wt.-% jute fiber were increased by 59%, 233%, 42%, 62% and 168% respectively. On the other hand, the thermal conductivity of the composite was decreased by 31% with the addition of 15 wt.-% of jute fiber. The minimum erosion wear rate was obtained for 15 wt.-% of jute fiber under impact velocity of 35 m/sec and angle of impingement of 90° and erodent size of 250 µm. Finally, ANOVA concluded that the impact velocity and jute fiber fraction played the most important role in influencing the erosion wear rate of PLA composite. Recommendation: For many construction and structural applications, jute PLA/fiber composite can be suitable due to excellent mechanical properties and low thermal conductivity.

Determination of microplastic pollution in marine ecosystems and its effective removal using an advanced nanobubble flotation technique

Microplastics (MPs), defined as plastic debris with a diameter <5 mm, have become a significant global hazard, posing risks to human health and the marine ecosystem. Assessing and efficiently removing MPs from marine water is crucial in preventing harm to marine life, human health, and the environment. This study aims to investigate the occurrence, abundance, and composition of MPs in marine waters in Hong Kong and propose the use of nanobubble flotation technology for their effective removal. The findings indicate that seawater samples collected from three locations within the study area exhibited high levels of MPs (82–137 particles/m3), with fragments and fibers being the most common shapes. The predominant size of MPs fell within the 0.1–0.5 mm range, with transparent being the dominant observed color. Given the prevalent environmental challenge posed by small-sized MPs, we investigated the implementation of nanobubble flotation (NB) technology as a novel approach to remove MPs <100 μm in size. Our results showed a significant improvement in removal efficiency, particularly for small-sized MPs (<50 μm) when using NB flotation compared to conventional dissolved air flotation (DAF). The superior removal efficiency of MPs through NB flotation is attributed to the small size and high concentration of NBs, which enhance particle-bubble collisions and adhesion, along with improved hydrophobic interactions.

Enhancing Nutritional Profile of Pasta: The Impact of Sprouted Pseudocereals and Cushuro on Digestibility and Health Potential.

We hypothesized that optimizing the formulation of pasta by incorporating sprouted pseudocereal flours, specifically quinoa (Chenopodium quinoa Willd) or kiwicha (Amaranthus caudatus L.) and cushuro (Nostoc sphaericum Vaucher ex Bornet & Flahault) flours, could offer the potential to simultaneously enhance nutritional quality and health-promoting properties in pasta. In this study, our objective was to optimize the formulation of composite flour (a ternary blend of wheat, sprouted pseudocereal, and cushuro flours) using a mixture composite design to maximize total soluble phenolic compounds (TSPC), γ-aminobutyric acid (GABA), antioxidant activity, and mineral bioaccesilability by reducing phytic acid (PA) content. Two optimal formulations were identified: one consisting of 79% wheat flour (WF), 13% SQF, and 8% CuF (oPQC), and the other composed of 70% WF, 15% SKF, and 15% CuF (oPKC). These optimized pastas exhibited reduced starch content and notably higher levels of total dietary fiber (1.5-3.61-fold), protein (1.16-fold), fat (1.3-1.5-fold), ash (2.2-2.7-fold), minerals (K, Na, Fe, Zn, Mg, Mn, and Ca), PA (3-4.5-fold), TSPC (1.3-1.9-fold), GABA (1.2-2.6-fold), and ORAC (6.5-8.7-fold) compared to control pasta (100% WF). Notably, the glycemic index of oPQC (59.8) was lower than that of oPKC (54.7) and control pasta (63.1). The nutritional profile of the optimized pasta was largely retained after cooking, although some significant losses were observed for soluble dietary fiber (18.2-44.0%), K (47.5-50.7%), Na (42.5-63.6), GABA (41.68-51.4%), TSPC (8-18%), and antioxidant activity (45.4-46.4%). In vitro digestion of cooked oPQC and oPKC demonstrated higher bioaccessible content of GABA (6.7-16.26 mg/100 g), TSPC (257.7-261.8 mg GAE/100 g), Ca (58.40-93.5 mg/100 g), and Fe (7.35-7.52 mg/100 g), as well as antioxidant activity (164.9-171.1 µmol TE/g) in intestinal digestates compared to control pasta. These findings suggest that the incorporation of sprouted pseudocereals and cushuro flour offers a promising approach to enhance the nutritional quality and bioactive content of wheat-based pasta, potentially providing health benefits beyond traditional formulations.

Impact of feed on the yield of Litopenaeus vannamei and Macrobrachium rosenbergii prawn culture from West Godavari district, Andhra Pradesh, India

Aquaculture, a vital sector addressing global food demand, is characterized by its extensive water requirements. Categorized into mariculture, freshwater aquaculture, and brackish water aquaculture, the sector plays a crucial role in food production. This study focuses on prawn cultivation, a significant aspect of aquaculture, emphasizing the influence of feed quality and hydrographic parameters on yield and ecological sustainability. Conducted in Vissakoderu village (Litopenaeus vannamei) and Eduru village (Macrobrachium rosenbergii), the research employed commercial feed, optimizing physicochemical parameters such as temperature, pH, and salinity. Probiotics were integrated into the feed to enhance prawn growth. Results indicated optimal levels of moisture, lipids, protein, fiber, carbohydrates, minerals, and vitamins in the feed. The progressive weight gain of prawns, reaching 30.00 kg for 1000 prawns, was correlated with an increased feeding frequency. Scientifically monitored hydrographic conditions and feed quality contributed to a remarkable average yield of 29 tons for Litopenaeus vannamei and 63.33 tons for Macrobrachium rosenbergii over three years. This underscores the importance of precision in aquaculture practices for both yield enhancement and ecological preservation. The study provides valuable insights into the sensitivity of prawn cultivation, emphasizing the need for meticulous care in managing hydrographical, feed, and disease parameters.

IL-10 dependent modulatory effect of regulatory B10 cells on local scar formation following Roux-en-Y choledochojejunostomy in a novel rat model

Choledochojejunostomy has been common surgical treatment of biliary tract disease. Scar formation at anastomotic often results in postoperative complications associated with bleak post-operative recovery, in which local inflammation may be a potential target to modulate local scar formation. This study investigated the effect of regulatory B10 cells on local scar formation through interleukin-10 signal pathway following Roux-en-Y choledochojejunostomy (RCJS) in a novel rat model. Sprague-Dawley (SD) rats with RCJS were randomly divided into blank group, experimental group, IL-10 blocking group, control group, and received different interventions and duration. Injected through dorsal vein of penis, rats in different groups were treated respectively according to scheme. These interventions were performed during surgery, on 1st day, and 2nd day after surgery. Related indexes, including blood examination, specimen tissue of anastomotic detection, were recorded and compared in different interventional groups. Rats in experimental groups had more rapid recovery in liver function and inflammatory index, and higher in IL-10 level. Flow cytometry analysis showed that rats in experimental groups had highest content of B10 cells and lowest content of CD4+CD25− T cells in peripheral blood. Wider anastomotic by macroscopical observation, and slighter proliferation of collagen fiber and smooth muscle fiber, lower α-SMA and TGF-β1 levels by pathological staining were detected in experimental groups. Higher expression of the IL-10 gene and lower expression of TGF-β1 at anastomotic were detected in experimental groups. B10 cells may relieve local inflammation of anastomotic following RCJS in rats through IL-10-dependent modulatory effect, and improve local scar formation.

Electrophysiological effects of mitochondria‐derived extracellular vesicles: implications for memory dysfunction in neurodegenerative disorders

AbstractBackgroundMitovesicles are a newly identified subtype of small extracellular vesicles (EVs) of mitochondrial origin. We recently developed a method to separate mitovesicles from other EVs after their isolation from the extracellular space of murine and human brain tissues. This method permits the study of the roles of mitovesicles in physiology and disease.Given their origin, we hypothesized that mitochondrial dysfunction, a hallmark of both Alzheimer’s disease (AD) and Down syndrome (DS), could induce alterations in mitovesicles, thus perturbing brain homeostasis and contributing to propagation of pathology. Therefore, we studied mitovesicle components and functionality after their isolation from the brain of a mouse model of DS (hereafter Ts2) as compared to diploid (2N) controls, as well as from frontal cortices of individuals with DS as compared to their age‐matched 2N controls.MethodBrain mitovesicles were isolated and analyzed by Western blotting, electron microscopy, nanotrack analysis, and monoamine neurotransmitter degradation assay as recently described (D’Acunzo, et al., 2022, PMID: 35962195). Coronal hippocampal slices from wild‐type mice were perfused with different subtypes of brain EVs, pretreated or not with clorgiline and pargyline (1 μM each), irreversible inhibitors of the monoamine oxidases type A and B (MAO‐A and MAO‐B), respectively. Long‐term potentiation (LTP) was induced at the level of the Schaeffer collateral fibers through a theta‐burst stimulation (Fà, et al., 2014, PMID: 24643165).ResultMitovesicle number is higher in brains of DS individuals and of Ts2 mice and contain a higher MAO‐B protein amount and enzymatic activity as compared to diploid controls, suggesting a potential mitovesicle‐dependent impairment of neuroamine homeostasis in DS. In agreement with that, Ts2 (but not 2N) mitovesicles stimulated a decreased LTP in recipient hippocampal slices as compared to vehicle control (Fig. 1; mtVs: mitovesicles). This biological activity was abolished when MAO‐B (but not MAO‐A) was blocked. The other EV subtypes of both genotypes, microvesicles and exosomes, did not trigger an effect on LTP. DS changes were found to be sex independent.ConclusionPathogenic mitovesicles are previously undescribed active players of the brain extracellular milieu by regulating LTP via MAO‐B, and potentially contribute to memory formation deficiencies typically found in AD and DS.

Inclusion effect of dietary fat and dietary fibre on growth performance and digesta mean retention time of young broilers fed on wheat/corn diets

Nutrient digestion and absorptions in animals are greatly influenced by the passage rate of digesta and the digesta passage rate or retention/residence time could be affected by the type of feed given. Therefore, the objective of this study was to examine the inclusion effect of dietary fat and fibre on digesta passage rate in broiler chickens. The hypothesis posited that the mean retention/residence time (MRT) of digesta would be elevated with higher levels of fat, whereas the addition of dietary fibre would have no effect on MRT. The study was designed as a 2 x 2 factorial arrangement of treatments, with two levels of dietary fat (low fat at 10 g/kg diet and high fat at 50 g/kg diet) and two levels of dietary fibre (0 g/kg diet and 40 g/kg diet). The meals were provided in mash form. The results of the present investigation indicated that dietary fat did not lead to a substantial increase in the total MRT of digesta in broilers, which contradicts the hypothesis of this study. However, the incorporation of a high level of fat has been found to increase body weight gain (BWG), improve feed conversion ratio (FCR) and reduce feed intake (FI). This effect has the potential to result in a more economically efficient production system, as it increases the amount of meat produced per kilogram of feed consumed. Further investigations on increasing digesta MRT are recommended in order to optimize the sustainable utilization of feed ingredients in broiler diets, particularly non-conventional feedstuffs, which involve in the application of feed enzymes such as enzymes that degrade fibre, phytate and other antinutrients present in feed.

Effects Of Crude Fiber, Organic Mater, And Crude Protein Contents In Sorgum Silage Of Samurai 2 First Ratoon

Samurai 2 Ratun 1st sorghum silage’s crude protein, organic matter, and fiber content will be examined in this research to see how curing time affects them. The experiment used a completely randomized design (CRD) with five treatments and four replications. In this study, the medications P1 (7 days of relief), P2 (14 days of restoration), P3 (21 days of restoration), P4 (28 days of restoration), and P5 (35 days of restoration) were tested. Samurai sorghum silage 2‘s rough fiber, natural matter, and unrefined protein content all showed a significant (P<0.01) effect of the restoration time on the results of the variety analysis. During the 35-day ripening period, the crude fiber content was higher, according to HSD’s subsequent tests. Non significantly different (P>0.05) after ripening for 28 days and significantly different (P<0.01) after ripening for 7 days, 14 days, and 21 days. Crude protein levels were found to be significantly (P<0.01) higher at 28 days of ripening than at 7 days and 14 days, but not significantly (P>0.05) different from those at 21 days and 21 days in the BNJ follow-up test. 35 days. When subjected to the P4 treatment for 28 days, the samurai variety 2 ratun to 1 sorghum silage produced the highest levels of crude protein, organic matter, and crude fiber, according to the study’s findings.

Characterization and nutritional valorization of agricultural waste corncobs from Italian maize landraces through the growth of medicinal mushrooms

The research investigates the potential use of maize cobs (or corncobs) from five genotypes, including the B73 inbred line and four locally cultivated landraces from Northern Italy, as substrate for implementing Solid State fermentation processes with four Medicinal Mushrooms (MMs). The corncobs were characterized based on their proximate composition, lignin, phenolics content (both free and bound), and total antioxidant capacity. Among the MMs tested, Pleurotus ostreatus and Ganoderma annularis demonstrated the most robust performance. Their growth was parametrized using Image Analysis technique, and chemical composition of culture samples was characterized compared to that of corncobs alone. In all culture samples, the growth of MMs led to a significant reduction (averaging 40%) in the total phenolics contents compared to that measured in corncobs alone. However, the high content of free phenolics in the cobs negatively impacted the growth of P. ostreatus. The final MM-corncob matrix exhibited reduced levels of free sugars and starch (≤ 2.2% DW, as a sum) and increased levels of proteins (up to 5.9% DW) and soluble dietary fiber (up to 5.0% DW), with a notable trend toward higher levels of β-glucan compared to corncobs alone. This research paves the way for the use of this matrix as an active ingredient to enhance the nutritional value of food preparations.

Tourists’ acceptability of enriched aadun snack produced from maize, soybean and ginger flour at Idanre hill, Ondo state

Blends of maize, soybean, and ginger flour were optimized. Aadun, a traditional snack made from maize that is high in starch but poor in protein, was made using the mixtures. For proximate composition and mineral composition, experimental runs (at various levels of substitution) were produced using the Response Surface Methodology's optimal mixture design. The flour mixtures were also utilized to make aadun, which was taste-tested by visitors to Idanre Hill and Resort. The findings showed that the enriched aadun had higher protein, fiber, ash, and fat levels, as well as higher mineral contents (sodium, potassium, phosphorus, and manganese), ensuring that the aadun was nutrient-sufficient for the tourists. The aadun will have a stable shelf life because of the snack's far lower moisture and carbohydrate content, which distinguishes it from most local snacks that are primarily starch-based and may contribute to obesity. The general acceptability of the enriched aadun revealed that it did not differ noticeably from the conventional aadun made from 100% maize flour in terms of acceptability.

Impact of Harvest Time on the Dry Matter Content, and Nutritional Parameters Related to Forage Quality of Maralfalfa (Cenchrus purpureus (Schumach.) Morrone, Poaceae) under Mediterranean Climate

Maralfalfa (Cenchrus purpureus (Schumach.) Morrone) is a productive fodder crop in tropical regions that has been evaluated for forage nutritional value in a Mediterranean climate. To assess the nutritional value, parameters including dry matter content (DM), ash, ether extract (EE), protein (CP), fiber contents (NDF and ADF), and the amino acids profile were determined at eight harvest times (HTs) in a non-fertilized and non-irrigated crop based in Silla (Valencia, Spain). The results showed significant differences in most of the parameters studied. While CP and ash significantly decreased over the eight HTs, NDF and ADF increased. In contrast, EE and the ratio of essential amino acids/total amino acids remained constant. Values of CP remained higher than 15% during the first two HTs (16 and 28 days). According to the analyses performed, the optimum HT can be stated at 28 days as it combines high levels of CP (including an optimal combination of essential amino acids) with low levels of fibers (NDF = 57.13%; ADF = 34.76%) and a considerable amount of dry matter (15.40%). Among the essential amino acids (EA) determined, lysine and histidine showed similar values (Lys ≈ 6%, His ≈ 1.70%) when comparing the composition of these EA to other forage species and cultivars studied, whereas methionine showed lower values. This work establishes the basis for the appropriate HT of maralfalfa according to the nutritional parameters measured. Further studies could be aimed to optimize the nutritional and phytogenic properties of maralfalfa to improve its value as a fodder crop, and to finally introduce it for sustainable livestock production in Mediterranean countries.

Kadar Serat dan Tekstur Kue Kembang Goyang dengan Substitusi Beras Merah Organik

Kembang goyang is Indonesian traditional snack, but it has quite low of dietary fiber and resistant starch content. Organic and nonorganic red rice could be used to increase level of dietary fiber by transforming it into red rice flour and used as a substitute of white rice flour in the making of kembang goyang snack. The purpose of this study is to determine type and substitution ratio of red rice flour into white rice flour to produce the best formulation of kembang goyang snack based on its dietary fiber content and texture. Kembang goyang snack is made by organic and nonorganic red rice flour with different ratios of red rice flour: white rice flour (0:100; 20:80; 40:60; 60:40; and 80:20). The result showed that organic red rice flour has lower yield (91,47 ± 0,23%) compared to nonorganic red rice flour's yield (92,80 ± 0,09%). In contrast, the dietary fiber content (8,09 ± 0,04%) and resistant starch content (3,95 ± 0,00%) of organic red rice flour is higher than the dietary fiber content (6,46 ± 0,07%) and resistant starch content (1,76 ± 0,03%) of non-organic red rice flour. Overall, the moisture content for both types of red rice flour ranged between 5,91 ± 0,08 to 6,35 ± 0,60%. The best formulation of kembang goyang snack is obtained by using organic red rice flour at ratio 40:60 of red rice flour and white rice flour. The product is classified as fiber-rich product and has similar texture (toughness and fracturability) to commercial product with 6,30 ± 0,01% of resistant starch content.
