| 中文摘要: |
| 以副干酪乳杆菌R8 为研究对象，筛选了冻干保护剂、益生元等包埋助剂，优化了微胶囊的包封方法，并
采用喷雾法将包埋液喷入固化液覆膜固化，制备出耐胃液、可定向释放的乳酸菌微胶囊，为规模化生产乳酸菌微胶
囊制剂提供了新方法。筛选出的最佳冻干保护剂为全蛋液，最佳益生元为菊粉；喷雾法制备微胶囊的条件为院喷雾压
力0.2~0.3 MPa，包埋液流量30 mL/min；最佳的包埋液配方为院菌泥5%，菊粉2%，全蛋液20%，海藻酸钠1%；最佳的
固化液配方为院壳聚糖0.5%，CaCl2 2.5%，乙酸1%。 |
| 英文摘要: |
| In order to provide a new method for large-scale production of lactic acid bacteria microcapsule, acid
resistant and directional release microcapsule of Lactobacillus paracasei R8 was prepared by screening the cryoprotectant
and prebiotics, optimizing the embedding method, and using spray method to solidify the microcapsule. The optimal
cryoprotectant was whole egg liquid, and the optimal prebiotic was inulin. Microcapsule preparation conditions were as
following spray pressure was 0.2 ~0.3 MPa, embedding liquid flow rate was 30 mL/min. The optimal composition of
embedding liquid was bacteria sludge 5%, inulin 2%, eggs 20%, sodium alginate 1%. The optimal composition of
solidifying liquid was chitosan 0.5%, CaCl2 2.5%, acetic acid 1%. |
