摘　　要：The use of silk sericin protein as a biomaterial to co-encapsulate probiotic Lactobacillus casei TISTR 1463 with alginate and various prebiotics was determined.In addition,0.2%silk sericin was also evaluated as a coating material to improve the viability of probiotic cells.Silk sericin coating has the potential to enhance probiotic survival in freeze-dried microcapsules.Under refrigerated storage condition of 4℃for 120 days,alginate-silk sericin-maltitol with silk sericin coating(ASM-C)provided the best performance with the lowest inactivation rate(k)and the highestδparameter(the first decimal reduction time)applied by the log-linear and Weibull models,respectively.However,the stability was relatively low at the temperature of 30℃.Co-encapsulation of alginate-silk sericin-prebiotic and coated with silk sericin exerted a protective impact on the strain survival when exposed to high temperatures and transited through the digestive system.
