阿拉伯木聚糖和海藻酸钠复合包埋植物乳杆菌的研究

In this paper, L. Plantarum was entrapped in the beads made from arabinoxylan and Sodium alginate by the extrusion technique. The effects of different concentrations of arabinoxylan, different contents of ferulic acid, different extraction ways of arabinoxylan, add AXOS (prebiotics) on the viability and controlled release of encapsulated L. Plantarum were investigated. Experimental results show that: compared with sodium alginate embedding group, arabinoxylans and alginate embedding group significantly increased the number of survival L. plantarum in artificial gastric juice; Increased the concentration of arabinoxylan, to some extent, significantly improved microcapsule protective effect, compared with control group, 6% arabinoxylan group increase the number of living L. plantarum 2.23 log.The higher content of ferulic acid, the better protection effect of microcapsule; there is no significant difference between water extraction arabinoxylan group and alkali extraction arabinoxylan group; Addition of prebiotics ( AXOS) can provided better protection effect. Increased the concentration of arabinoxylan, enhance the content of ferulic acid and alkali arabinoxylan can effectively prolong its release upon exposure to intestinal pH.
