【摘要】 将水溶性的茶多酚通过冷喷雾法微胶囊技术变成油溶性的茶多酚,通过正交试验得到壁材的组成是乳化剂A∶B∶C为8∶0.3∶1.7,其包埋程度达67.5%。微胶囊茶多酚在油中分散均匀,在油脂中的抗氧化效果明显优于BHA、PG。更多还原

【Abstract】 The processing of oil- soluble tea polyphenols (TP) was studied,made by of microencapsulation of technique of cold spray method,dried in vacum. The optimum composition of the wall materials was investigated by orthogonal arrays as follows: emulsifiers A: B: C =8:0.3:1.7? Microencapsulating rate of tea polyphenols was 67.5% . The product could disperse equally in oil and its antioxidation effect in oil was better than propyl gallate (PG) and butylated hydroxyanisole (BHA).更多还原
