A Mediation Model of Food Literacy: A Potential Relationship between Body Image Dissatisfaction and Body Mass Index.

Background and Objectives: The global rise in obesity presents a significant public health challenge, with Turkey exhibiting one of the highest obesity rates in Europe. Body image dissatisfaction (BID) and lower food literacy (FL) have been associated with obesity, yet their interplay remains underexplored. This study aimed to investigate the relationship between body mass index (BMI), body image dissatisfaction, and FL in adults in Turkey. Materials and Methods: In total, 759 women and 419 men aged 18-64 years old were included in this study. The mean age was 31.34 ± 11.92. A total of 1178 participants completed an online questionnaire assessing anthropometric measurements, BID, using the Stunkard Figure Rating Scale, and FL, using a validated questionnaire. The data were analyzed using descriptive statistics, correlation analysis, and mediation analysis to explore the relationships between variables in SPSS 24.0. Results: Women desired to be thinner more frequently than men, and those with negative BID were predominantly individuals with overweight or obesity. Moreover, those with higher FL scores were more likely to be satisfied with their bodies. Correlation analysis demonstrated a negative relationship between BMI and FL (r = -0.94; p = 0.001) and a positive relationship between BMI and BID (r = 0.628; p < 0.001). Mediation analysis revealed that FL mediated the relationship between BID and BMI (β = -2.281; lower limit = -3.334, upper limit = -1.228). Conclusions: The findings highlight the importance of addressing BID and enhancing FL to mitigate obesity risk factors. This study contributes to understanding the complex interplay between BID, FL, and obesity, providing insights for public health interventions aimed at obesity prevention and management.

A Novel Facet of In-Hospital Food Consumption Associated with Hospital Mortality in Patients with Scheduled Admission-Addition of a Study Protocol to Test the Existence of Effects of COVID-19 in the Same Study in the Post-COVID-19 Period.

Humankind has faced unexperienced pandemic events since 2020. Since the COVID-19 pandemic has calmed down, we felt the need to verify whether in-hospital mortality had worsened compared to pre-pandemic conditions due to the COVID-19 pandemic. To test the hypothesis that daily food consumption is associated with in-hospital mortality during hospitalization and to provide baseline data to examine whether the effects of COVID-19 exist or not in post-pandemic period. All hospitalized patients staying in a single institution on the third Thursday of May, August, November, and the following February were included. Compared data: (1) among four seasons, (2) between age < 75 vs. ≥75 years, (3) between <75% vs. ≥75% of in-hospital food, and (4) logistic regression analysis to identify factors associated with in-hospital mortality. In 365 inpatients, the following results were obtained: (1) no seasonality or age effect in in-hospital mortality, (2) the novel cutoff value of 75% of the hospital food requirement was used to identify poor in-hospital survivors, (3) logistic regression analysis showed low food consumption, with <75% of the hospital food requirement as the predictor of high in-hospital mortality. A small eater of in-hospital food < 75% during hospitalization was associated with significantly higher in-hospital mortality in patients with scheduled hospitalization in the pre-pandemic period. Then, a study protocol is proposed to test the existence of the effects of COVID-19 in the same study in the post-COVID-19 period. This study protocol is, to our knowledge, the first proposal to test the effects of food consumption in the post-COVID-19 period on in-hospital mortality in the clinical nutritional areas.

Food security among black breast cancer survivors in Maryland: insights from an online pilot study.

Food security, and reliable access to nutritious food, is essential for maintaining health yet remains elusive for many, including U.S. patients with breast cancer (BC). Research specifically focusing on public health consequences of food insecurity in BC survivors is limited. We addressed this gap by exploring the relationship between food security and various sociodemographic, clinical, and cancer-related factors among Black BC survivors in Maryland. The parent study engaged Black female BC survivors in Maryland through digital campaigns and referrals, achieving 100 completed surveys. Food security was assessed through an online follow-up survey with the six-item short form from U.S. Department of Agriculture (USDA), leading to a binary classification for analysis from raw scores. Statistical analysis involved descriptive analysis and Chi-square tests to explore the relationship between food security status, various BC risk factors, and follow-up survey response status. Of the 31 participants who participated in the follow-up survey, 11 (35.5%) were categorized as having low food security. We observed significant associations between food security status and both income (< $40,000; chi-square p = 0.004) and education levels (high school/GED; chi-square p = 0.004). In comparing respondents to non-respondents, significant differences in employment (p = 0.031) and health insurance status (p = 0.006) were observed. Our descriptive findings demonstrate the importance of further studies evaluating food security screenings in Black BC survivors to enable targeted interventions aiming to improve overall health outcomes and equity in cancer survivorship care.

Assessment of performance and egg quality in laying hens of Spanish indigenous breed Black Castellana as compared with a selected white egg-layer strain

Indigenous animal genetic resources should be preserved because of their well adaptation to the environment, their tolerance to low food availability and their sociocultural importance. The characterization of the quality of the products generated by heritage breeds may bring more arguments to encourage the raising of these animals. This study aimed at evaluating the egg performance and quality of Spanish indigenous Black Castellana (BC) breed as compared with a selected strain (Lohmann LSL-Classic). Four groups of 30 hens were arranged: 1) Lohmann hens fed a control diet; 2) BC hens fed the control diet; 3) Lohmann hens fed a diet including linseed at 70 g/kg (omega-3 diet); 4) BC hens fed the omega-3 diet. Egg production was higher by 12.3% for Lohmann hens but, since BC eggs were heavier by 15.4%, no effect of genetics was found on daily egg mass. Feed intake was higher by 5.0% for BC hens. Nonetheless, no difference was detected for feed conversion ratio. Eggshell was thicker by 6.78% in Lohmann eggs. Haugh units did not differ among freshly laid and stored eggs in Lohmann hens, whereas Haugh units decreased in stored BC eggs (80.5 vs. 76.7 vs. 72.3 at 0, 14, and 30 d of storage). Yolks of BC eggs contained less fat (57.5 vs. 60.8% DM), more protein (32.8 vs. 31.9% DM) and more cholecalciferol (1.25 vs. 1.22 μg/g DM), and showed lower proportion of saturated fatty acids (29.0 vs. 37.0%) and higher proportions of monounsaturated (45.7 vs. 39.6%) and polyunsaturated (25.2 vs. 23.4%) fatty acids. Feeding the omega-3 diet reduced the yolk proportions of saturated (32.5 vs. 33.5%) and monounsaturated (42.0 vs. 43.3%) fatty acids and increased those of polyunsaturated (25.4 vs. 23.2%) and ω-3 (7.05 vs. 2.42%) fatty acids. No effect due to genetics or diet was found on yolk color score or on yolk content in cholesterol, cobalamin, retinol and γ-tocopherol. This study represents the first exhaustive characterization of eggs from Spanish indigenous Black Castellana breed.

IGF-1 Acts through Kiss1-expressing Cells to Influence Metabolism and Reproduction.

Kisspeptin, encoded by the Kiss1 gene, ties puberty and fertility to energy status; however, the metabolic factors that control Kiss1-expressing cells need to be clarified. To evaluate the impact of IGF-1 on the metabolic and reproductive functions of kisspeptin producing cells, we created mice with IGF-1 receptor deletion driven by the Kiss1 promoter (IGF1RKiss1 mice). Previous studies have shown IGF-1 and insulin can bind to each other's receptor, permitting IGF-1 signaling in the absence of IGF1R. Therefore, we also generated mice with simultaneous deletion of the IGF1R and insulin receptor (IR) in Kiss1-expressing cells (IGF1R/IRKiss1 mice). Loss of IGF1R in Kiss1 cells caused stunted body length. In addition, female IGF1RKiss1 mice displayed lower body weight and food intake plus higher energy expenditure and physical activity. This phenotype was linked to higher proopiomelanocortin (POMC) expression and heightened brown adipose tissue (BAT) thermogenesis. Male IGF1RKiss1 mice had mild changes in metabolic functions. Moreover, IGF1RKiss1 mice of both sexes experienced delayed puberty. Notably, male IGF1RKiss1 mice had impaired adulthood fertility accompanied by lower gonadotropin and testosterone levels. Thus, IGF1R in Kiss1-expressing cells impacts metabolism and reproduction in a sex-specific manner. IGF1R/IRKiss1 mice had higher fat mass and glucose intolerance, suggesting IGF1R and IR in Kiss1-expressing cells together regulate body composition and glucose homeostasis. Overall, our study shows that IGF1R and IR in Kiss1 have cooperative roles in body length, metabolism, and reproduction.

Overview on the role of dietary Spirulina platensis on immune responses against Edwardsiellosis among Oreochromis niloticus fish farms

Edwardsiellosis is a bacterial fish disease that mostly occurs in freshwater farms and is characterized by a high mortality rate. Edwardsiella tarda strain was recovered from 17 fish out of 50 Nile tilapia, which were harboring clinical signs of systemic septicemia. The level of un-ionized ammonia (NH3) in the fish farm’s water was 0.11–0.15 mg/L, which was stressful for the Nile tilapia.Sequencing of the gyrB1 gene confirmed that the isolate was E. tarda JALO4, and it was submitted to NCBI under the accession number PP449014. The isolated E. tarda harbored the virulence gene edw1 AHL-synthase (quorum sensing). In addition, the isolate was sensitive to trimethoprim and sulfamethoxazole mean while it was intermediate to florfenicol. The median lethal dose (LD50) of E. tarda JALO4 was determined to be 1.7 × 105 CFU/mL in Nile tilapia.In the indoor experiment, Nile tilapia (45.05 ± 0.4 g), which received dietary Spirulina platensis (5 and 10 g/kg fish feed), showed optimum growth and feed utilization. Meanwhile, after receiving dietary S. platensis, the fish’s feed conversion ratio (FCR) was significantly enhanced compared to the control, which was 1.94, 1.99, and 2.88, respectively. The expression of immune-related genes interleukin (IL)-1β and tumor necrosis factor (TNF)-α were upsurged in E. tarda-challenged fish with higher intensity in S. platensis groups. Dietary S. platensis at a dose of 10 g/kg fish feed could provide a relative protection level (RPL) of 22.2% Nile tilapia challenged against E. tarda. Nile tilapia experimentally infected E. tarda, drastically altering their behavior: higher operculum movement, low food apprehension, and abnormal swimming dietary S. platensis (10 g/kg fish feed) could rapidly restore normal status.It was concluded that Edwardsiellosis could alter Nile tilapia behavior with a high loss in fish population. Fish received dietary-S. platensis could rapidly restore normal behavior after E. tarda infection. It is recommended the incorporation of S. platensis at doses of 10 g/kg into the Nile tilapia diet to boost their immunity and counteract E. tarda infection.

Dielectric properties during the heating process of savory and sweet coconut‐/almond‐based bread in the microwave region

AbstractFor microwave‐assisted heating, accurate knowledge of the dielectric properties (DPs) plays a key role for optimizing the heating process. In this paper, the DPs of four different bread dough formulations are presented from 300 MHz to 20 GHz. The base dough was prepared with almond powder, coconut powder, eggs, cashew nut powder, ghee butter, and cardamom. In addition, three more honey‐sweetened formulations were prepared with honey, goat milk and cacao. The DPs were measured during the complete baking process, from room temperature up to 80°C. It is shown that in all cases, ε′ and ε″ decrease as frequency increases. In addition, a second‐order Debye equation was extracted for all formulations showing two relaxation times (τ1 and τ2), which can be seen in the Cole–Cole plot. Moreover, it is shown that in all formulations, as temperature increases, ε′ and ε″ also increase, which is a typical trend for low moisture foods. Finally, the penetration depths are calculated for all formulations.Practical ApplicationsThe dielectric properties (DPs) of four different bread dough formulations are provided covering a wide band in the microwave range from 300 MHz to 20 GHz. DPs are useful for the development of microwave‐assisted heating applications, where prior knowledge of the DPs permits the optimization of the heating process. In addition, penetration depth is necessary as this parameter allows to calculate the maximum depth that the microwave energy will heat up the sample.

Prevalence of Irritable Bowel Syndrome (IBS) in the Arab World: A Systematic Review.

Irritable Bowel Syndrome (IBS) is a common functional pathology of the gastrointestinal tract (GIT) across the globe. The prevalence rate of IBS varies across the regions. In the present systematic review, we aim to investigate the prevalence of IBS in Arab countries in recent years. To identify relevant studies, a comprehensive search was undertaken in various databases including CINAHL (Cumulated Index to Nursing and Allied Health Literature) Ultimate, Scopus, PubMed, and Web of Science. Furthermore, Google Scholar was also explored to identify relevant studies. The inclusion criteria included studies that assessed IBS in the Arab world and were published in the English language. Fifty-two cross-sectional studies from seven countries, encompassing 51,683 participants, were included. The majority of the included studies were conducted in Saudi Arabia (n=40), followed by Jordan (n=4) and Egypt (n=3). The highest prevalence rates were reported by studies from Saudi Arabia, Lebanon, and Jordan. Low prevalence rates (<20%) were noted in 19 studies included in this systematic review. Female predominance in IBS prevalence was observed in most studies, while only two studies indicated higher prevalence in males. Key risk factors included family history, anxiety, depression, gastroesophageal reflux disease, low income, diabetes, low water intake, workload, occupation, food allergy, smoking, age, chronic diseases, and stress. IBS prevalence in the Arab world varies significantly. Female predominance was seen in the present systematic review as well.

Reversing Severe Chronic Kidney Disease Before and After COVID-19 Infection With a Whole-Food, Plant-Based, Low Inflammatory Foods Everyday (LIFE) Diet

Stress relief of chemo illness.

New studies (Tang et al. 2024. J. Exp. Med.https://doi.org/10.1084/jem.20231395) describe a liver stress pathway that is activated by certain chemotherapeutic drugs, which in turn induces a peptide hormone which partially mediates the lower food intake and body weight loss during chemotherapy treatment.

Physicochemical characteristics of tea seed starches from twenty-five cultivars

The physicochemical features of starches separated from tea seeds of 25 cultivars were analyzed. The distinct characteristic of tea seed starches was that they had high apparent amylose content (AAC, 28.94–39.91 %) and resistant starch contents (4.64–8.24 %), suggesting that tea starch can be used for production of low glycemic index food. One cultivar (T12) had smallest breakdown (74.2 RVU) and highest gel hardness, indicating it performed stably during shear thinning, resulting in a firm texture. Another cultivar (T25) had a peak viscosity of 417.6 RVU, a large breakdown and small setback, suggesting a low tendency for retrogradation. There was a range of 61.6 °C to 77.5 °C for the peak gelatinization temperature and 0.163 to 0.390 for the flow behavior index values. These parameters could serve for selecting suitable starches with minor differences in physicochemical properties for food use. Correlation analysis indicated that AAC is a key factor determining starch retrogradation properties. The broad genetic diversity in the tea seed starch physicochemical features provided potentially versatile applications in the food industry. The results gained from the present study contribute to a better understanding of tea seed starch quality, and encourage its application in many value-added food products.

Tillage practices in the north west region of Cameroon and their consequences on soil physio-chemical properties - a review

Tillage practices make up one of the most essential operations executed on the soil during crop production. They manipulate the soil by mechanical means using tools, implements, and powered machinery with the intention to prepare the soil and make it suitable for plant growth. For the adoption of sustainable agriculture, tillage practices carried out in a particular region and their consequences on soil health need to be assessed. This review article identified traditional, conventional, and conservation tillage as the major tillage systems employed by farmers during crop cultivation in the North West Region of Cameroon. Traditional tillage practices (traditional ridging, burning in ridges (“Ankara”), and slash and burn) were highly predominant especially among small-holder farmers, followed by conservation tillage. Conventional tillage practices were the least practiced among farmers. Due to the less adoption of conventional and conservation tillage, soils in the region are mainly affected by the identified widely used traditional tillage practices. Traditional ridging exerted beneficial effects on the soil such as improved soil water conservation, increased soil nitrogen, and soil organic matter contents while burning in ridges and slash and burn exerted negative consequences on the soil by declining soil fertility, destroying soil physical properties and reducing overall land productivity. Due to the adoption of poor tillage techniques, soil degradation is rampant in the region placing the population at risk of low land productivity and food insecurity. The adaptation of improved tillage practices such as traditional ridging is thus required for sustainable soils and increased food security. Int. J. Agril. Res. Innov. Tech. 14(1): 70-76, June 2024

ANALYZING THE CAUSES OF WATER SHORTAGE, LOW CROP YIELD, AND FOOD CRISIS IN PAKISTAN: A LONGITUDINAL ANALYSIS (1991-2019)

Pakistan has been facing problem of low crop yield, food shortage, and high prices of food items, and it has to import food items for billions of dollars every year to meet domestic needs. The literature shows a sufficient gap to investigate the causes of low crop yield. This motivates the authors to investigate the causes of water shortage, low crop yields, and high prices of agriculture inputs, using 28 years of data spanning from 1991 to 2019. The selected variables include crop yield as the dependent variable and water availability, precipitation, seed, fertilizer, and pesticides as independent variables. Various statistical techniques such as descriptive statistics, Correlation matrix, ADF test, ARDL Model, Bound test, and Error Correction model were employed to determine the relationship between variables. The findings reveal that all independent variables except precipitation have a positive association with crop yield. The comparison of the results of ARDL and ECM Models shows that the variables water, seed, fertilizer, and pesticides have a significant and positive relationship with crop yield in the short run rather than in the long run. In light of these findings, the study suggests that the Government of Pakistan should build water storage, ensure the availability of agriculture inputs at subsided prices, and introduce modern agriculture technologies to enhance crop yield to ensure food security and save billions of dollars being spent on the import of food items every year.

Deepening our understanding of the environmental influences on the reproductive dynamics of the main fishery stock of Argentine hake, Merluccius hubbsi, in the southwestern Atlantic Ocean

AbstractThis study analyzed the inter‐annual variability in the reproductive dynamics of the Argentine hake from Patagonian waters during the last 20 years concerning the environmental conditions and the nutritional status of females. Macroscopic and histological information on gonadal maturity, female condition factor (K), and oceanographic data at different sampling sites throughout the studied region were obtained from research surveys carried out during the main spawning season of this species. Four stages, according to the maturity ovarian phases composition, were assigned annually at each sampling site to assess reproductive dynamics: vitellogenesis, ovulation, regression, and resting. The spatial pattern of inter‐annual variability in reproductive dynamics was described, and the influence of temperature and female condition on the probability of ovulation and regression was assessed using generalized linear models. The area with the lowest inter‐annual variability in the hake reproductive dynamics was observed between 43 and 45°S (50 to 80 m depth) in relation to ovulation events. The vitellogenesis stage was more frequently found adjacent to the reproductive area, whereas the regression was mainly observed in deeper waters. Both bottom and surface temperatures explained the ovulation and regression stages, showing a positive and negative relationship, respectively. Lower values of the K factor, associated with low food availability, were further linked to the occurrence of regression. Finally, it is worth noting that the relationship observed between the ovulation/spawning dynamics of Argentine hake and water temperature suggests that the reproductive success of this species could be affected in the future scenario of climate change.

The Impact of Food Insecurity on Maternal and Neonatal Outcomes

Purpose: The purpose of this study was to examine the relationship between food security status and pregnancy outcomes. Methods: This was a single-center cross-sectional cohort study of postpartum women in Indianapolis, IN. A validated 10 question Household Food Security Survey module was used to assess food security for patients who spoke English, Spanish, or Haitian-Creole. Correlating with the USDA definitions of food security, total scores were “high,” “marginal,” “low,” and “very low.” Scores were analyzed as inadequate (marginal, low, or very low) vs. adequate (high) food security. If a score fell within any category but “adequate” food security, patients were provided with information on community resources. Prenatal and postpartum data were abstracted via chart review, collecting: standard demographics, language, parity, diagnosis of diabetes, diagnosis of hypertensive disorder(s), pre-pregnancy weight, weight at time of delivery, BMI at time of delivery, gestational age at delivery, Edinburgh Postnatal Depression Scale (EPDS) score, and delivery mode. Neonatal variables included: weight and sex. The primary outcome was occurrence of gestational diabetes (GDM). These outcomes were compared between patients who had adequate vs. inadequate food security. Logistic regression was used to examine the association between food insecurity and each of the dichotomous outcomes. Linear regression was used to model the relationship between sex-specific birthweight z-scores and food insecurity. All adjusted models included language and maternal age. The Indiana University institutional review board approved the study (IRB# 14116). Results: Two hundred six surveys were completed from June 2022 through December 2022. Ninety-three participants (45.4%, 95% CI 38.4-52.4%) were categorized as inadequate food security. The incidences of marginal, low, and very low food security were similar with 31, 30, and 28 participants, respectively. Race/ethnicity and language were different between adequate and inadequate groups (p=0.006 and &lt;0.001 respectively). The incidence of GDM was 7.9% and was not different for those with inadequate food security (OR 0.96 95% CI 0.33-2.68). Food insecurity was protective against delivery via C-section (aOR 0.50 95% CI 0.25-0.98). Food insecurity increases odds of EPDS &gt; 9 (aOR 4.32 95% CI 1.41-16.2). Conclusions: Inadequate food security status is highly prevalent in our patient population and was associated with racial/ethnic minority status and non-English speaking populations. Inadequate food security was found to be associated with a decreased odds of cesarean delivery and higher odds of postpartum depression.

Uneven consequences of global climate mitigation pathways on regional water quality in the 21st century

Future socioeconomic climate pathways have regional water-quality consequences whose severity and equity have not yet been fully understood across geographic and economic spectra. We use a process-based, terrestrial-freshwater ecosystem model to project 21st-century river nitrogen loads under these pathways. We find that fertilizer usage is the primary determinant of future river nitrogen loads, changing precipitation and warming have limited impacts, and CO2 fertilization-induced vegetation growth enhancement leads to modest load reductions. Fertilizer applications to produce bioenergy in climate mitigation scenarios cause larger load increases than in the highest emission scenario. Loads generally increase in low-income regions, yet remain stable or decrease in high-income regions where agricultural advances, low food and feed production and waste, and/or well-enforced air pollution policies balance biofuel-associated fertilizer burdens. Consideration of biofuel production options with low fertilizer demand and rapid transfer of agricultural advances from high- to low-income regions may help avoid inequitable water-quality outcomes from climate mitigation.

Editorial: Underutilized Ingredients in Innovative Food Formulations

ABSTRACT The rapid change in eating habits and consumer demands for healthy food are the driving motives for food industries to formulate new food products. Innovative food formulations are either very expensive or based on targeted customers. Low glycemic foods, fiber enriched products, plant-based meat formulations, and functional foods are predominating the in-food innovations. However, to attain sustainability and promote zero food waste, it is extremely important to explore food byproducts and underutilized food sources. Among food byproducts, peels, seeds, pomace have great potential and can be used for the extraction of bioactive and functional components for subsequent incorporation in innovative food formulations. Similarly, millets are excellent sources of quality proteins and sweet potatoes are rich sources of bioactive carbohydrates, proteins, carotenoids, and minerals. Innovative formulations are not only based on innovative ingredients but also innovative or modern food processing can contribute toward better food products in terms of functional, nutritional, and quality attributes.

Factors associated with prolonged length of stay in dengue hemorrhagic fever patients at Wangaya Hospital, Denpasar, Bali

Background: Dengue hemorrhagic fever (DHF) is a vector bone disease which is being a serious public health concern in tropical and sub-tropical countries around the world. A high number of dengue cases are reported annually in Bali. Prolonged hospital stays affect the high cost of dengue treatment. The aim of the study was to analyze the factors associated with prolonged lengths of stay in dengue hemorrhagic fever patients. Methods: This study was an analytic observational study with a retrospective study design. The data was collected from the medical records of DHF patients at Wangaya Hospital between January - May 2024. The data analysis method used was the Chi square test as a bivariate test. Results: A total of 152 subjects, mostly DHF patients, were male (54.61%), &lt;40 years old (73.68%), without comorbid disease (71.05%), without low food intake (56.58%), and with a length of stay ≥4 days (66.45%). Most of the patients (&gt;50%) had clinical symptoms of fever (100%), headache (91.45%), and myalgia (83.55%). A statistically significant association was found between comorbid disease and prolonged length of hospital stay with a p value of 0.039 (p&lt;0.05), and low food intake showed a significant association with prolonged length of stay with a p value of 0.001 (p&lt;0.05). Conclusions: This study identified that comorbid disease and low food intake were factors associated with prolonged lengths of stay in DHF patients. Findings of this study may still prove beneficial for physicians to do early identification of DHF patients who have high risk factors for prolonged hospitalization, which can be an effective tool to combat the increasing disease burden.

Performance of nursery Litopenaeus vannamei post-larvae in a BFT system enriched with Rhizoma coptidis broth

The shrimp farming industry has historically been limited by outbreaks of bacterial diseases. The current study aimed to investigate the performance of adding Rhizoma coptidis (R. coptidis), an herbal medicine, to the biofloc system of Litopenaeus vannamei culture. A broth of boiled R. coptidis was added to four experimental groups (C0 (control), C2, C4, and C6, with respective dry weights of 0, 2, 4, and 6 g/L R. coptidis). The results showed that the nitrase and dehydrogenase activities of the biofloc enriched with R. coptidis were enhanced compared to the control group. Shrimp reared in the systems enriched with R. coptidis showed significantly better growth performance, digestion, and immune enzyme activity and a lower food conversion ratio compared to the control group. The mortality rate for Groups C4 and C6 in a Vibrio infection test was less than 50 %, while Group C0 experienced 100 % mortality. There were no significant differences in ammonia or nitrite concentration among the treatment groups. These results suggested better performance of nursery Litopenaeus vannamei post-larvae in BFT systems by enrichment with 4 g/L R. coptidisL broth.

Value Addition of Defatted Groundnut Cake

Objective of this study was to prepare defatted groundnut cake flour &amp; develop value added products from it. Groundnut cake flour blends easily and enhances or enriches the nutritive value of products prepared from it. Value added products like laddoo and chutney were prepared from defatted groundnut cake flour. Laddoos were prepared by blending defatted groundnut cake flour with coconut powder in the proportion 55:45 as well as chutney was prepared by mixing defatted groundnut cake flour with roasted chana dal in the proportion 55:45. Nutritional quality parameters namely moisture, protein, fat, carbohydrate, total minerals, crude fiber and energy of defatted groundnut cake flour and its value added products were determined. This study proved that these products can be substitute fat rich and adulterated low quality food products which are often being marketed and consumed. Keywords: groundnut cake, defatted flour, value added products, nutritional quality
