Several health benefits have been associated to orange-fleshed sweet potato owing the existence of various bioactive compounds, including β-carotene. The purpose this study was establish effect ultrasound and steam treatment on bioaccessibility β-carotene, total polyphenols, antioxidant activity, polyphenol oxidase, peroxidase color in juice. Sweet juice processed using (0.66 W cm−2 8 min), (2 a combination ultrasound. β-carotene increased juice, with samples treated by showing highest (76.6%). Processing had no or enzyme but resulted significant changes As processing technology, enables preservation improvement quality when conbined other treatments, facilitates development new products.
