Abstract
This study aimed to devise an environment-friendly and effective, yet simple and practicable, antioxidant extraction and encapsulation method from Riceberry bran, whose extract was used thereafter for developing highly efficient antioxidant capsules. Ethanolic Riceberry bran extracts with high total phenolic content, total flavonoid content, total anthocyanin content, and antioxidant activity (using DPPH radical scavenging activity and ferric reducing antioxidant power assay) were obtained using ultrasonic-assisted extraction. The optimum conditions for producing the capsules, such as types of gelatin, concentrations of gelatin, and the Riceberry bran extract concentrations, were studied. Capsules produced by incorporating 1% (w/v) of acid-treated gelatin (type A) and 1% (w/v) of Riceberry bran extract yielded higher chemical properties. When dispersed in water at 37 °C, the capsules exhibited a high release of antioxidants. Moreover, the capsule showed a lower degradation rate of antioxidants under simulated gastrointestinal conditions compared to the crude extract.
