Development and Evaluation of Nutritional and Quality Standard of Beef Burger Supplemented with Pumpkin (Cucurbita moschata) Seed Flour

The composition of pumpkin seeds includes bioactive compounds, proteins, polyunsaturated fatty acids, and dietary fibers. Thus, the objective of this research was to develop and evaluate the nutritional and quality standard of beef burgers supplemented with pumpkin seeds (Cucurbita moschata) added in different proportions. To process the pumpkin seed flour (PSF), the seeds were sanitized, dried in an oven, crushed, and sieved. Through such means, three formulations of beef burgers were prepared, named S (without the addition of PSF), F5 (with the addition of 5% (w/w) of PSF), and F10 (with the addition of 10% (w/w) of PSF). The respective results for burgers P, F5, and F10 were as follows (w/w): proteins 17.61%, 18.04%, 19.86%; lipids 12.19%, 12.42%, 14.55%; ash 1.77%, 1.86%, 1.94%; fibers 0%, 0.88%, 1.76%; phenolic compounds 39.55, 82.93, 90.30 (mg/g); and total antioxidant capacity 11.09%, 18.48%, 24.45%. Regarding the sensory analysis attributes, tasters gave sample F10 scores lower than 7. However, the standard and F5 samples showed results higher than 7 for all parameters. For the determination of shelf life, an expiration date of 30 days was established. It was observed that adding PSF to industrialized products adds nutritional value with the inclusion of polyunsaturated fats, phenolic compounds, and dietary fibers.

Effect of citrus peeling (Citrus sinensis) on production performance, humoral immunity, nutrients, and energy utilization of broiler quails

Citrus citrus peeling has a wide range of vitamins and trace minerals that have antioxidant and antimicrobial properties. It is hypothesized that the addition of citrus peeling to broiler quail diets can improve their production performance, humoral immunity, nutrients, and energy utilization. A trial was performed to study the impact of a methanolic extract of citrus peeling (Citrus sinensis) on production performance, humoral immunity, nutrients, and energy utilization of broiler quails. A healthy day-old 300 quails were randomly assigned with 5 replicates each replicate had 15 birds and used CRD for the trial. Different dietary supplementations were presented to different groups. The control group was not supplemented with any supplementation in their feed. While, the 3 other groups were supplemented by 0.5 mL/kg, 1 mL/kg, and 1.5 mL/kg of methanolic extract of dried Citrus sinensis peel (DCSP) in the basal diet (DCSP0.5, DCSP1, and DCSP1.5 groups, respectively). All the birds were allowed ad libitum feeding and water. The feed intake and FCR were significantly higher in the control group, followed by DCSP0.5, and then DCSP1. The significantly lowest feed intake and FCR were observed in the DCSP1.5 group. The weight gain and dressing % were significantly improved with the increasing level of methanolic extract of Citrus sinensis. The significantly highest weights of thymus, spleen, and bursa were recorded in the DCSP1.5 group, followed by the DCSP1. The antibody titers against infectious bursal disease, New Castle disease, and infectious bronchitis disease were significantly higher in the DCSP1.5, DCSP1, and DCSP0.5 groups than in the control group. It was concluded from the study that supplementation of quails with methanolic extract of citrus at a dose rate of 0.5 to 1.5 mL/kg of feed can improve feed intake, weight gain, FCR, dressing percentage, relative weight of lymphoid organs, and digestibility coefficient. Supplementation of Citrus sinensis has also concluded positive impacts on antibody titers against various viral diseases. The best improvement in the evaluated parameters was observed at a dose of extract of citrus was 1.5 mL/kg of feed.

Zinc bioaccessibility in finger millet porridge blended with zinc-dense mushroom

Introduction

Zinc deficiency is a common health problem among people who rely heavily on cereal-based foods. Consequently, most people from low-income families, particularly young children in Sub-Saharan Africa, who rely mainly on cereal-based meals, have suffered from Zinc deficiency-related health issues. It is therefore recommended that children who show signs of zinc deficiency like poor growth and cognitive impairment be fed zinc-rich meals; however, in severe cases, they should be given zinc supplements to reduce risks of morbidity and mortality. In that regard, since edible mushrooms are nutritionally rich and contains essential minerals as well as health-promoting compounds, they are a promising tool for improving the nutritional and health quality of commonly carbohydrate-rich foods.

Objective

The objective of this study was to examine the Zinc bioaccessibility and sensory properties of HMT finger millet porridge blended with Zinc-dense mushroom.

Methods

Oyster mushroom (Pleurotus ostreatus) was grown on rice straw enriched with zinc sulfate at various concentrations. After reaching full maturity, the mushrooms were harvested, dried, and milled into a fine powder. Zinc-rich mushroom powder was mixed with millet flour in various proportions and used to prepare porridge. The zinc bioaccessibility in millet-mushroom flour blends was determined using a simulation method of gastro intestinal digestion. In addition, panelists comprising of mothers and caregivers of children aged between 6 and 23 months were asked to evaluate the sensory attributes of millet-mushroom porridge.

Results

Adding Zinc to growth substrates had a significant (p˂0.05) effect on mushroom yield. Control substrates without Zinc yielded 120 g of mushroom per kilogram substrate. However, when 100 mg Zinc was added to the substrate, the yield increased by 65.6%. The study further noted that substrates with Zinc beyond 100 mg had a negative effect on mushroom yield. Consequently, substrates with the highest Zinc level (600 mg) produced the lowest mushroom yields. Increasing substrates Zinc content, on the other hand, had positive effect on mushroom Zinc levels. Substrates without Zinc produced mushrooms containing 8.9 mg Zinc, which increased by 30.9% when 600 mg Zinc was added. Furthermore, HMT finger millet porridge without mushrooms had a phytates: Zinc molar index of 60.3, which decreased to 34 when 20% (w/w) mushroom proportions were added. Despite having the highest bioaccessible Zinc with the least effect on texture and appearance, a 20% mushroom proportion in HMT finger millet porridge considerably compromised the taste, aroma and general consumer acceptability.

Conclusion

Amending HMT finger millet flour with mushroom powder improved Zinc bioaccessibility of the porridge. However, when added beyond a certain limit, mushroom reduced organoleptic qualities of the porridge, which affected overall consumer acceptance. The study recommends, therefore, that mushroom powder be added to finger millet flour in the appropriate proportions to enhance nutritional and health benefits of porridge while minimizing possible negative impacts on sensory properties.
