Nitrogen recycling during phenylpropanoid metabolism in sweet potato tubers

Noodles made from sweet potato can be a healthier alternative to commercially produced ones since it is rich in vitamins and minerals. The product has no artificial preservatives, and the sweetness of its taste comes naturally from the sugar content of the Camote tubers. The project is the second phase of a study on the development of nutri-noodles made from the tubers and tops of sweet potato. The study determined the physicochemical and microbial analysis and shelf-life of the product and verify its acceptability through quantitative testing. The sample was submitted to Department of Science and Technology Region V for analysis and the results were: 6.53% moisture, 0.13% free fatty acids and <150 CFU/g of yeast and mold count. Moreover, nutrition facts were also computed, Calories is 231, Total Fat= 4%, Cholesterol= 0%, Sodium= 4%, Total Carbohydrate= 6%, Dietary Fiber= 28%, Magnesium =13% and Vitamin B6= 12%. The shelf-life of the product is six months stored at room temperature. The Nutri-fried noodles were served with vegetable toppings, and as rated by the panelists the result was liked very much. After analyzing the quality characteristics of the product, it is recommended that the sample is ready for production and marketing.

The study was conducted to determine the production in vitro and in vivo of cellulases by Botrydiplodia theobromae and Rhizopus oryzae. Isolates of these organisms were obtained from the postharvest decay of sweetpotato tubers. Results revealed that B. theobrornae and R. oryzae which were isolated from postharvest spoilage of sweetpotato tubers produced endo-13-1,4-glucanase and exo-V-1 ,4-glucanase in culture and in fungi-infected tissues of sweetpotato tubers. The optimum temperature and pH for cellulose synthesis and activity were 30°C and pH 6.5, respectively.

Abstract Sweet potato is primarily used for nutrition and medicinal purposes. This study was done to determine proximate analysis and anti-nutritional factors of sweet potato tubers. The sample was randomly purchased fromTepi local market. Then it was analyzed for moisture content, ash content, crude fiber content, oxalate content and acid content. The result of the study showed that 87.6% moisture content, 7.5% ash content, 7.46 mg/100 gm oxalate content, 4.3% crude fiber content and 0.09 M acid content.
