Abstract

Background: In order to ensure human health and raise the standard of living for people, plants and their crops have been extremely important. Yams are extremely important for both food security and medicine in poor nations. Dioscorea alata, a species of yam, provides an advantage for sustained production because of its relatively strong agronomic traits. This study's main goal was to generate composite food products, and the yam's relatively strong agronomic characteristics offer a sustained production advantage. Methods: The food items that were created, namely biscuits, had improved nutritional value. Composite biscuits were made by combining wheat flour with D. alata flour in three distinct formulas (5%, 10%, and 15%). Results: D. alata Yam's compositional analysis revealed that the samples with and without peels had the following contents: moisture (69.13±1.48%) and 66.85±1.47%); ash (2.11±0.03%) and (1.99±0.19%); fat (0.40±0.80%) and 1.07±0.12; crude fiber (2.06±0.12%) and (2.57±0.22%); protein (2.4±1.39) and (6.31±0.34) and carbohydrates (28.01±1.40%) and (28.24±1.52%), respectively. Overall, composite flour can be used as an unusual ingredient in baked goods. Based on the sensory evaluation, the results indicated that biscuits made with 5% composite flour were superior to those made with 10% and 15% composite flour. Conclusion: It was shown that food products manufactured with composite flour can nevertheless have properties that are comparable to those made with whole wheat flour. Overall, the test panelists found the created biscuits (5% DAYF integrated) to be satisfactory in terms of appearance, color, flavor, taste, and texture.

Abstract

Background: Watermelon juice is a refreshing drink to quench the extreme tropical heat thirst. Packed with simple carbs, antioxidants, vitamins, and minerals, it boosts immunity and aids in the body's recovery from dehydration. Moreover, it’s a delicious and filling drink. A study was carried out to investigate the effects of ethanolic extracts on watermelon juices. Methods: Physicochemical changes such as total soluble solid, vitamin C, acidity, pH, non-enzymatic browning reaction, sensory evaluation, and total viable count were measured at 7-day intervals over 28 days. Results: The findings showed that clove and sodium benzoate had a greater effect on unpasteurized juice than black pepper and sodium benzoate on pasteurized juice. Clove and sodium benzoate outperformed the others in unpasteurized juice. For unpasteurized and pasteurized juice, black pepper and sodium benzoate showed greater results than others. Besides, sodium benzoate (3.10×102, 1.2×102, 0×102, and 1.0×102) and cinnamon (4.0×102, 2.2×102, 3.0×102 and 2.0×102) presented better antimicrobial activity than others for unpasteurized juice. Sodium benzoate (3.0×102, 1.10×102, 0×102, and 2.0×102) and black pepper (1.20×102, 2.1×102, 2.0×102, and 1.10×102) displayed better antimicrobial activity than others for pasteurized juice. For both unpasteurized and pasteurized juice, cinnamon and sodium benzoate were comparatively more popular than others. Conclusions: Based on the findings, these extracts could be employed as natural antimicrobial preservatives instead of artificial preservatives in watermelon juice to increase its shelf life.
