Abstract

The invention relates to probiotic microcapsules as well as a preparation method and application thereof. The probiotic microcapsules comprise a core material and a wall material, wherein the core material is probiotics; the outer layer of the wall material is coated with chitosan; the wall material is prepared from an aqueous solution containing a natural polymer material and a freeze-drying protection agent; the freeze-drying protection agent comprises one or more of glucose, fructose, sucrose, lactose, trehalose, soluble starch, glycerin, mannitol, Arabic gum, dextran 40 and skim milk; the natural polymer material comprises one or more of gellan gum, xanthan gum, k-carrageenan, sodium alginate, cellulose acetate phthalate or gelatin; in the aqueous solution, the volume fraction of the freeze-drying protection agent is 4.0%-20.0% and the volume fraction of the polymer material is 0.5%-5.0%. The probiotic microcapsules can keep excellent acid resistance and storage stability before and after being freeze-dried.

Description

technical field

[0001] The invention relates to the technical field of probiotic products, in particular to a probiotic microcapsule and its preparation method and application. Background technique

[0002] Probiotic products have a wide market and are mainly used in yogurt fermentation in food. Lactic acid bacteria ferment lactose to produce a large amount of organic acids such as lactic acid and acetic acid, which lowers the pH value of the intestines, making the intestines in an acidic environment, and has obvious inhibitory effects on pathogenic bacteria such as Salmonella, Proteus and Escherichia coli. In addition to pathogenic bacteria, it also has a strong inhibitory effect on intestinal spoilage bacteria. Low pH value is conducive to intestinal peristalsis, maintains normal physiological functions, and prevents the reproduction of pathogenic bacteria. For example, lactobacillus tablets, which are often used in clinical practice, are well received in terms of treati...
