Abstract

The invention takes protein and a reducing oligosaccharide Maillard product as microcapsule wall materials and applies the protein and the reducing oligosaccharide Maillard product to the production of probiotic microcapsules. A wall material solution is prepared by reaction of following components: the whey protein and isomaltooligosacharide are mixed according to the mass ratio ranging from (1:1) to (10:1) to form a solution, heating treatment is carried out at a constant temperature of 85-95 DEG C for 2-4 hours, Maillard reaction is carried out to generate grafts with different contents, which are used as a wall material solution. The concentrated probiotics are used as a core material, and an endogenesis emulsification gel method and a spraying and drying method are used for producing the probiotic microcapsules. The microcapsule wall materials comprise the milk-based protein and the prebiotics, have nutritional and functional properties and have a wide application range. A Maillard product is used as a wall material structure and is dense, so that the protection capability is enhanced; the fixed point releasing capability is enhanced in the presence of intestinal canal enzymes and intestinal canal microorganisms; and after the releasing, the microcapsule wall materials can provide nutrients for the probiotics. The prepared microcapsules are used as function factors, have a good market prospect and can be used for medicine, food and feed industries.

Description

Technical field [0001] The present invention is the field of micro -capsule technology. Specifically, it is the application of protein and reducing hypocruster glycogen. Background technique [0002] Probiotics are defined by the Food and Agricultural Committee (FAO) and World Health Organization (WHO) as a type of microorganisms that can be beneficial to the human body in the human intestine.How to protect probiotics under the condition of human digestive tract to maintain vitality to achieve the role of probe in the specified location is a problem to solve the food industry.Therefore, studying how to maintain a high number of probiotics transmission and release the target position and the release of colonization after the release is the main problem. [0003] At present, more methods are used to protect probiotics with microcapsules.Commonly used single wall materials include sodium algina, chitosan, other polysaccharides (vascus, cellulose derivatives, transgender starch, etc....
