摘要: 为了提高益生菌对不良环境的抗性,使其以活性状态到达肠胃并发挥相应的功效,采用微胶囊包被与冷冻干燥相结合的技术,以实验室分离的鸡源乳杆菌为对象,设计L9(34)正交试验,筛选制备乳杆菌微胶囊的最佳配方,并检测乳杆菌微胶囊的特性。试验结果证明,海藻酸钠浓度为3%,氯化钙浓度为2%,脱脂奶粉浓度为4%,乳糖浓度为6%时,制备的微胶囊中活菌包埋产率最高,达到92.40%,且产品具有较好的耐酸性与肠溶性,在室温下具有较好的贮存稳定性。

Abstract: In order to improve the resistance of probiotics on the adverse environmental, and to make them reach the stomach by active state and play the corresponding effect, use bacteria that our laboratory isolated as experimental objects, and use the technology of microcapsules coated with a combination of freeze-drying, design L9 (34) orthogonal test, to filter the best formula of preparation of microencapsulated Lactobacillus,and detection the characteristics of Lactobacillus microcapsules. The test results proved that with the sodium alginate concentration of 3%, calcium chloride concentration of 2%, skim milk powder concentration of 4%, lactose concentration of 6%, the embedding yields of viable bacteria in microcapsules reached 92.40%, and the product has good acid resistance and intestinal-lysis,and it has good storage stability at room temperature.

Key words: Lactobacillus from chicken; microcapsules; freeze drying; orthogonal test
