Abstract

This study investigated the amino acid composition, phytochemicals, and antioxidant activities of cookies prepared from blends of orange-fleshed sweet potato and Pleurotus tuber-regium sclerotium. Most of the amino acids of the cookies showed higher values than their corresponding flours. The highest contents of tannins, oxalate, and hydrogen cyanide were found in orange-fleshed sweet potato (OFSP) flour while sclerotium inclusion resulted in increased saponins and alkaloids. Antinutrients of the developed cookies were substantially lower than their corresponding flours. The OFSP flour and cookies showed the highest β-carotene, flavonoids, and phenolic contents. Developed cookies showed higher (p˂0.05) phytochemicals and antioxidant activities than wheat cookies. However, phenolics and flavonoids increased in cookies because of baking while β-carotene and antioxidant activities decreased. This study showed the potentials of OFSP and P. tuber-regium sclerotium composite flour as an alternative food ingredient for protein-enriched functional cookies with potential health benefits.
