Seasonal fluctuations in fatty acid profile and biochemical traits of edible deep-water shrimp Heterocarpus woodmasoni

Heterocarpus woodmasoni is an edible deep-sea caridean shrimp that holds significant commercial importance and is sourced from the south-west coast of India in the Arabian Sea. In this research study, we extensively examined the biochemical, mineral and seasonal fatty acid compositions of H. woodmasoni. ANOVA tests, unveiled noteworthy disparities (p < 0.05) in moisture, crude fat and protein content between male and female H. woodmasoni. In contrast, we observed no significant differences in ash, carbohydrate, and cholesterol levels. Regarding minerals, the prominent macro elements detected in H. woodmasoni included K, P, Na, Ca and Mg with Zinc (Zn) and manganese (Mn) emerging as the dominant micro elements followed by Copper (Cu) and Selenium (Se). Notably, these shrimp exhibited a well-balanced ratio of essential to non-essential amino acids. Within the n-6 series, linoleic acid (18:2n-6), dihomo-γ-linolenic acid (20:3n-6), and arachidonic acid (20:4n-6) were identified as the primary polyunsaturated fatty acids (PUFA), exhibiting distinct concentrations across sexes and seasons. Both male and female H. woodmasoni displayed lower atherogenicity and thrombogenicity indices, ranging between 0.4 and 0.6 and 0.2–0.4, respectively, indicating a favourable cardiovascular health profile. Principal component analysis resulted in a two-principal component model explaining 83.4 % and 67.3 % of the total data variance for amino acid and fatty acid indices, respectively. This comprehensive biochemical analysis of both male and female H. woodmasoni reaffirms the species' status as a valuable and healthful resource, characterized by its abundance of high-quality nutritional components.

Coal pore size distribution and adsorption capacity controlled by the coalification in China

The coalification process significantly influences the composition of coal material and the development of pore size, ultimately affecting the adsorption capacity of coal seams and the extraction of coalbed methane. This project aimed to assess the pore structure and gas adsorption capacity of coal samples from nine key sedimentary basins in China. The N2 test results revealed that during the initial stage of coalification, micropore, transition pore, and mesopore dominate in order of magnitude. In the subsequent coalification stages, the development of mesopore is most significant during the second jump, while the transition pore becomes more prominent in the third jump. Additionally, the findings from nuclear magnetic resonance tests indicate that the proportion of adsorbed pore demonstrates a decreasing-then-increasing trend throughout the coalification process. The first and second coalification jumps primarily contribute to the development of adsorption pore and seepage pore, whereas the third jump mainly focuses on adsorption pore development. The gas adsorption capacity is influenced by various factors such as pore structure, material composition, and chemical structure. During the first coalification jump, gas adsorption mainly occurs in the adsorption pore. In the second jump, medium gas adsorption capacity is achieved due to the combined effects of enhanced adsorption pore development and reduced moisture and ash content. Finally, the third coalification jump exhibits highly developed adsorption pores, the lowest moisture and ash levels, and a sufficient aromatic structure in the chemical composition, resulting in high adsorption capacity. These findings contribute to a deeper understanding of the variations in coalbed methane enrichment across different basins in China, with coalification playing a crucial controlling role.

Apparent Influence of Anhydrite in High-Calcium Fly Ash on Compressive Strength of Concrete

This case study investigates five fly ashes with high CaO and SO3 levels in their chemical composition and compares the apparent influence of the presence and absence of anhydrite on compressive strength. Another distinguishing feature of the above ashes is that they, more or less, naturally contain anhydrite. Two different series of mixed proportions were adopted. Series 1 is designed to understand the maximum possible replacement level of fly ash. Series 2 is designed to understand the effect of anhydrite on compressive strength development. The mineral composition and glass phase of fly ashes were determined by X-ray diffraction Rietveld analysis. As a result of this study, we have found that concrete containing anhydrite-rich fly ash exhibits a higher strength than concrete containing anhydrite-free fly ash at all ages. The compressive strength increases with an increasing fly ash replacement ratio when anhydrite-rich ash is used, but strength decreases when the replacement level exceeds a certain point. The optimal amount of anhydrite was 2 ± 0.5 kg/m3 of concrete, excluding the anhydrite contained in cement.

Proximate Composition and Functional Properties of Soyabeans (Glycine Max) Enriched Carbohydrate Diets

This study explored enhancing the nutritional value and functional properties of carbohydrate-rich diets by incorporating soybeans into millet, cassava, and yam. Soybeans, known for their high protein, unsaturated fats, and micronutrients, were used to fortify these staple foods. Proximate analysis assessed the macronutrient content of both the original and soybean-enriched samples, while functional properties such as water and oil absorption capacities, swelling index, bulk density, and gelation capacity were evaluated. Results showed significant increases in protein content, particularly in the millet-soybean mixture (29.81%), with relatively low levels of fat and ash. Functional assessments indicated millet’s highest gelation capacity and cassava’s superior water absorption. These findings suggest that soybean fortification can improve carbohydrate-rich diets’ nutritional quality and versatility. Further research is recommended to assess the impact of these dietary modifications on human health and consumer acceptance.

Optimization of ultrasonic-assisted extraction of soluble dietary fiber (β-glucan) from different barley varieties and study of its characterization and functional attributes.

Green technology, encompassing sustainable practices in food production, extends to dietary fiber extraction. This study aimed to enhance dietary fiber extraction from the selected barley varieties (Jou-17, Sultan-17, and Pearl-21) using the ultrasonic-assisted extraction (UAE) technique. This process involved washing, drying, de-fatting (using ethanol as green solvent), and protein removal steps. The response surface methodology (RSM) technique was used to optimize the yield of soluble dietary fiber (SDF; β-glucan) with time, temperature, and power. Optimal conditions yielded the highest SDF (5.21%) in all selected varieties after 17.5 min at 41.70°C with 130.5 W. FTIR pattern confirmed the functional group in the tested sample. TGA and DSC spectra determined the thermal of SDF (β-glucan). Monosaccharide composition confirmed that SDF (β-glucan) is glucose in nature. Proximate analysis indicated that Jou-17 had the highest moisture (13.4%) and crude fiber (10.10%) content. Sultan-17, on the other hand, had the maximum levels of ash (2.75%), crude fat (1.22%), and protein (8.84%). The NFE, water-holding capacity, oil-holding capacity, and foaming capacity of extracted SDF (β-glucan) in the "Pearl-21" barley variety were determined to be 78.37%, 14.07 g/g, 6.99 g/g, and 126.17%, whereas highest foaming-stability (96.26%) was observed in Jou-17 variety. PCA also confirmed the association in studied variables. In a nutshell, optimizing the extraction of SDF (β-glucan) from the selected barley varieties using green technology and its favorable properties opens up promising paths for future endeavors and contributes to the advancement of sustainable and health-conscious practices in the food industry.

The proximate analysis revealed that avocado seed meal is rich in protein (17.32%), fat (15.33%), and carbohydrates (48.73%), with moderate levels of moisture (10.26%), ash (2.39%), and crude fiber (5.97%). Phytochemical analysis indicated high contents of phenols (111.56 mg/g), saponins (96.94 mg/g) and flavonoids (66.66 mg/g), but lower levels of alkaloids (14.60 mg/g), tannins (1.17 mg/g), and steroids (0.89 mg/g). The antioxidant properties assessed showed significant DPPH (50.05%) and FRAP (63.04%) free radical scavenging activities, though lower inhibition of lipid peroxidation (34.88%) and vitamin C content (0.03 mg/g). Enzymatic inhibition assays demonstrated alpha-lipase, alpha-glucosidase, and alpha-amylase inhibition rates of 31.46%, 27.56%, and 50.88%, respectively. Anti-inflammatory properties were also notable, with 24.02% albumin denaturation inhibition and 37.99% antiprotease activity. These findings suggest that avocado seed meal holds considerable potential for nutritional and therapeutic applications as natural feed supplement for livestock and humans.

Nutritional and Techno-Functional Properties of Noodles with Orange Fleshed Sweet Potatoes and Bio-fortified Beans

Noodles are popular globally and their consumption is on the rise. Conventional noodles are often lacking in nutrients. Substituting part of wheat flour with nutrient-rich ingredients can improve their nutritional value, though it may alter product properties. This study aimed to evaluate the properties of noodles made with partial substitution of wheat flour with orange-fleshed sweet potatoes (OFSP) and bio-fortified beans (BFB). Nutrient-enhanced noodles were produced using an optimized processing protocol developed previously with response surface methodology (RSM). The protocol included substituting wheat flour with 21.5% OFSP and 5.5% BFB. The noodle processing conditions were dough thickness (2 mm), drying temperature (80°C) and time (143 mins). The control sample of noodles were made using plain wheat flour. Proximate analysis, carotenoids, minerals (iron and zinc), cooking properties and colour were determined. The control sample of noodles were made using plain wheat flour. Results were subjected to a t-test using SPSS and the difference in means was considered significant at p&lt;0.05. The nutrient-enhanced noodles showed significantly higher levels of ash, protein, dietary fiber, iron, zinc, and beta-carotene than the control. They also exhibited higher cooking loss (8.98 versus 6.22%) and cooking yield (219.88 versus 184.73%). The noodles samples varied in colour values (L*a*b*) and visual appearance with the control exhibiting a higher L* value, lower a* value, and lighter appearance. The study suggests that substituting wheat flour with OFSP and BFB in noodle production enhances the nutritional value and impacts on physical properties. Therefore, incorporating nutrient-rich ingredients e.g. OFSP and BFB could create convenient and nutritious foods.

Hydration characteristics and hydration products of calcium sulfoaluminate cement and fly ash blended pastes

This study investigated a binary blend of calcium sulfoaluminate cement and fly ash with a target compressive strength of more than 32.5 MPa based on the EN 197-1 standard, using as much fly ash as possible. In the binder system of calcium sulfoaluminate cement and fly ash, a decrease in the replacement level of fly ash results in an increase in compressive strength. Mortar with a 40% replacement level of fly ash for calcium sulfoaluminate cement and added gypsum shows 49.41 MPa strength at 28 d. Its hydrates are hydroxy-AFm, ettringite, crystalline aluminum hydroxide, amorphous aluminum hydroxide, strätlingite, and monosulfate. They are attributed to the hydration of ye’elimite, C2S, and C3A in calcium sulfoaluminate cement. The reactivity of fly ash is not observed until 28 d of hydration. The formation of ettringite is the main cause of the gains in compressive strength.

Paleoenvironmental reconstruction of a Neogene diatomite deposit from La Pampa Province (Argentina)

Diatomite deposits constitute siliceous biogenic sedimentary rocks primarily composed of diatoms. In Argentina, there is a scarcity of paleoenvironmental reconstructions for these deposits. This study focuses on the analysis of the diatom content in a Plio-Pleistocene diatomite from La Pampa Province. The aim is to identify diatom diversity and reconstruct the evolution of paleoenvironments. The studied section of 4.40 m is located at the CP site (38°08′40.5′’S; 67°09′23.2′’W, El Sauzal Formation). The profile is a laminated white diatomite with three levels of volcanic ash. Seven samples 50 cm-equidistant were extracted and oxidized with H2O2 for diatom analysis. 500 valves/slide were counted in order to calculate relative abundances. Diatom zones were defined using CONISS. The analysis revealed 72 morphospecies, with 28 of them exhibiting abundances > 4%. The diatom flora is predominantly composed of small fragilarioid diatoms accompanied by Discostella, Aulacoseira, Epithemia, Rhopalodia, and Cymbella species, indicating a lacustrine origin. At the base, a paleolake with a relatively alkaline pH, low nitrogen concentrations and high phosphates (volcanic ash) favored the growth of a diverse diatom community. Towards the top, the dominance of fragilarioids, the decrease in freshwater planktonic taxa and the presence of gypsum suggest a shallower environment with increased salinity during the drier periods of the Plio-Pleistocene.

Chemical Characteristic and Sensory Evaluation of Biscuit Prepared from Wheat and Aleppo Pine Seeds Flour.

This study aimed to explore the potential use of Aleppo pine seed flour as a nutritious ingredient in biscuit production. Aleppo pine seed flour was blended with wheat flour to create biscuits with varying proportions: 15%, 30%, and 45% Aleppo pine seed flour. The analysis of the chemical composition of the biscuits revealed that increasing the proportion of Aleppo pine seed flour led to higher levels of protein, fat, and ash, while the carbohydrate content decreased. Sensory evaluation showed that biscuits with 15% Aleppo pine seed flour and 85% wheat flour had favorable characteristics in terms of color, flavor, crispness, and overall appeal. These findings indicate that incorporating Aleppo pine seed flour into wheat flour can enhance the nutritional profile of biscuits, offering higher protein, fat, and mineral content. The study suggests that a blend containing 15% Aleppo pine seed flour is optimal for producing biscuits with desirable sensory properties, making it a promising alternative ingredient for healthier biscuit formulations. Overall, this research highlights the potential of Aleppo pine seed flour to improve the nutritional quality of biscuits without compromising their sensory qualities, paving the way for its use in health-conscious baking practices.

Pengaruh Penggunaan Abu Bata Merah Sebagai Filler Pada Aspal Porus Terhadap Karakteristik Marshall

Roads are an important infrastructure for the community in mobilizing. Therefore, it needs special attention in terms of safety and comfort. In several parts of Indonesia, during the rainy season, especially in North Aceh District, Lhoksukon often experiences flooding and the water inundates the roads. This disrupts road users and mobilization. Porous asphalt is a flexible pavement which has excellent advantages for countries with tropical climates such as our country, Indonesia. The advantages of porous asphalt are planned to have large cavities so that they can absorb water freely. In this study the authors will examine the use of red brick ash as a filler obtained at a brick factory in Blang Panjoe Village, Peusangan District, Bireuen Regency. The varying levels of brick ash as filler in porous asphalt mixtures are 0%, 30% and 50%. Furthermore, the determination of KAO and the manufacture of porous asphalt mixing specimens were carried out with red rock ash as a filler substitute of 0%, 30% and 50%. The maximum percentage variation in brick ash content was obtained at 50% substitution with a stability value of 591 kg, a yield value of 3.27 mm, MQ 181.26 kg/mm and VIM 18.8%. The results of the research on the stability and flow values and the Marshall parameters meet the AAPA specifications.

Chemical Composition and Nutritive Value of Sea Buckthorn Leaves.

Sea buckthorn leaves (SBT_LVs) form notable by-product during harvesting and post-harvest management of the berries. It is already known that sea buckthorn berries are important for their chemical composition and based on this, they occupy a wide field in nutrition. SBT_LVs also have a rich chemical composition, like the berries. The aim of this study was to describe these by-products in the context of protein and complex carbohydrates-dietary fiber fractions, including qualitative and quantitative composition of amino acids. Proximate composition, amino acids, nutritional values of the protein, and dietary fiber fractions of SBT_LVs of four cultivars (cvs.) Ascola, Habego, Hergo, and Leikora were assessed. SBT_LVs from different years of the study had statistically different levels of crude protein, ether extract, crude ash, and nitrogen-free extract (NFE), confirming that the quality of the raw material (leaves) can be significantly modified by habitat conditions. The largest fraction of dietary fiber was neutral detergent fiber (NDF), including the sum of hemicellulose, cellulose, and lignin, followed by the acid detergent fiber fraction (ADF), consisting of lignin and cellulose. The content of essential amino acids in SBT_LV protein was high. Overall, this study confirms that SBT_LVs hold promise as a valuable resource for use as a food ingredient, functional food, and dietary supplement for both humans and animals.

Revisiting biomass compositions determination using thermogravimetric analysis and independent parallel reaction model

The determination of biomass composition via thermogravimetric analysis (TGA) has been a subject of considerable interest for many years. The current work proposes a revised workflow for determining the amounts of cellulose, hemicellulose, and lignin in biomass by combining TGA under an inert atmosphere with analyses of extractives and ash. An independent parallel reaction (IPR) model used for the deconvolution of the derivative thermogravimetry data was improved by constraining model parameters, i.e., thermal decomposition kinetic parameters and char fractions of cellulose, hemicellulose, and lignin, with values compiled from the literature using statistical analysis. The workflow is developed and demonstrated using cellulose and starch mixtures and then applied to biomass with varying levels of ash, including pine, birch, and oak wood, switchgrass, and pine bark. Using extractive-free biomass in the new TGA-IPR workflow improved the composition results compared with untreated biomass. The compositions determined by this method agreed well with values reported in the literature (within approx. 8 wt%) for the tested samples. The results demonstrate improved biomass composition accuracy using an accessible and rapid TGA-based approach.

Traits of Mortadella from Meat of Different Commercial Categories of Indigenous Dairy Cattle.

The rising interest in healthier meat options prompted the exploration of alternatives to traditional pork-based products, incorporating meat from different livestock species, feeding regimens, and functional ingredients. This study investigates the production of healthier meat products by examining the physicochemical traits, fatty acid profile, and sensory properties of mortadella made with Cinisara meat of four young bulls and four adult cows, and four females of the Nebrodi Black Pig. All the animals were fed principally on natural resources. Nutritional analysis revealed different levels of moisture, protein, fat, and ash in raw materials, with pistachios contributing to a healthy fatty acid profile rich in monounsaturated and polyunsaturated fatty acids. Formulations using cow meat exhibited higher fat content and caloric value, resulting in sensory attributes such as more intense color, improved fat cube adhesion, and pronounced odors compared to young bull and control mortadella. Fatty acid analysis demonstrated distinctive profiles influenced by the meat type used and, as expected, bovine products showed higher contents of rumenic and other conjugated linoleic acids. Pork mortadella displayed greater ω6 and ω3 values, with a healthier ω6/ω3 ratio comparable to those found in cow products. Young bull mortadella showed the worse atherogenic and thrombogenic indices. The findings underscore the impact of raw materials on the nutritional and sensory attributes of mortadella, emphasizing the necessity for interventions to enhance fatty acid composition in processed meat products.

Exploring the effects of supplementing monoterpenoids in Moringa oleifera based-diet in Oreochromis niloticus: Improving the growth performance, feed efficiency, digestibility and body composition

Monoterpenoids are interesting hydrocarbons typically found in essential oils and have a significant role in medicinal and biological purposes. The goal of this study was to investigate the effects of two monoterpenoids, carvacrol (CAR) and menthol (MEN), supplemented with Moringa oleifera leaf meal (MOLM) based diets on growth parameters, digestibility and body composition of Nile tilapia (Oreochromis niloticus). Alongside the basal diet (control-T1), nine experimental diets supplemented with categorized levels of CAR and MEN at 200, 300 and 400 mg/kg individually and their mixtures (MIX) (1:1) (CAR-T2, 200; T3, 300; T4, 400 mg/kg, MEN-T5, 200; T6, 300; T7, 400 mg/kg and MIX- (1:1) T8, 200; T9, 300; T10, 400 mg/kg) were fed to the fingerlings (6.55 ± 0.03 g) for the period of 60 days. Monoterpenoids supplementation led to significantly (p<0.05) better growth, feed utilization and nutrient digestibility in comparison to the control group. The highest growth, feed efficiency and nutrient digestibility were noticed in fishes fed with a diet supplemented with 200 mg/kg MIX. Interestingly, fishes fed with diets containing monoterpenoids had significantly higher levels of protein and ash, but with lower lipid in comparison to the control group. Conclusively, the dietary supplements like CAR and MEN improved the health status of Nile tilapia when given either individually or in a mixture,. Specifically, the MIX at 200 mg/kg was the optimal supplementation for the fishes.

Influence of αs1-casein genetic variant in buffalo milk and rennet coagulation properties

Buffalo milk, recognized for its rich composition, including higher levels of fat, lactose, protein, and ash when compared to cow milk, has been insufficiently studied considering its genetic diversity within the buffalo population in Serbia. This study focuses on the analysis of the CSN1S1 472G&gt;C variant and its potential impact on rennet coagulation properties, critical for cheese production. Rennet coagulation parameters (rennet coagulation time (RCT), setting time (ST), aggregation rate (AR), and gel firmness (GF)), along with fresh curd yield (Yf), were examined in both, raw and high heat-treated buffalo milk. Genotyping results, obtained through Sanger sequencing of blood samples from 30 female buffaloes, revealed the presence of three CSN1S1 472G&gt;C genotypes: GG, GC, and CC. The rheological measurements, conducted using dynamic small amplitude oscillatory rheology (SAOR), indicated significant statistical differences (p&lt;0.05) among the tested parameters for these CSN1S1 472G&gt;C genotypes in both raw and heat-treated buffalo milk. In addition, the influence of genotype on the yield of fresh curd in fresh and thermally treated milk was studied. These results can contribute to optimization in the process of production and processing of buffalo milk, emphasizing the importance of understanding the genetic factors in the composition of buffalo milk and its technological properties.
