Different Drying Duration of Corncobs Powders and Its Effects on Physical, Nutritional and Phytochemical

Corncobs are one of the agricultural wastes that have nutritional and functional content. The advantages processing corn cobs into powder include durability, a smaller volume, lighter weight, making it easier to pack transport. One important steps in is drying determine durability quality powder. This study aimed different durations corncobs powders their effect on physical, nutritional, phytochemical properties as an alternative food foodstuffs. experimental design used Completely Randomized Design (CRD), consisting factor with four treatments: 4;5;6;7; 8 hours replications. results showed times had significant (p<0.05) properties. duration 7 has best physical (water absorption at 1.34 ml/g, solubility 26.76%, whiteness 66.62%, bulk density 0.64 g/cm3), contents content 10.26%, ash 3.73%, protein 2.20%, fat 0.77%, carbohydrate 83.04%, crude fiber 35.77%), (total phenol 113.30 mg/100 mg, antioxidant activity 21.28%, tannins 1.46 mg/L).The implication this result can be developed source nutrients bioactive compounds convert waste value-added products.
