A production method for preparing suspendable lactic acid bacteria wet capsules with low energy consumption

Abstract

The invention discloses a method for producing a suspended lactobacillus wet capsule with low energy consumption. The method comprises the following steps that lactobacillus is cultured; lactobacillus liquid is centrifuged; lactobacillus sludge is suspended; the lactobacillus sludge and a sodium alginate solution are stirred and emulsified to form turbid liquid; calcium carbonate turbid liquid and the lactobacillus sludge and sodium alginate turbid liquid are emulsified and centrifuged; particles are collected; the collected particles are mixed with chitosan, emulsified and centrifuged; and a microcapsule is washed by sterile water in a suspension manner. According to the method, a processing technology and used reagents are improved on the basis of classical wall materials, namely sodium alginate and chitosan, so that the energy consumption is low, the probiotic microcapsule particles are small, and the viable bacterium lethality is low. In addition, the microcapsule particles prepared with the method are added into liquid food to form colloid, so that suspension without settling is achieved; a taste of the food is not affected; the high activity of probiotics can be kept for 90-120 days, and can be kept for more than half a year after a protective agent is added; the activity of thallus can be kept for more than one year; and a requirement on the shelf life of the food can be met fully.

Description

technical field [0001] The invention belongs to the field of microcapsule preparation, in particular to a production method for preparing wet capsules capable of suspending lactic acid bacteria with low energy consumption. Background technique [0002] Microencapsulation is a technology in which trace substances are wrapped in polymer films, and is a micro-packaging technology for storing solids, liquids, and gases. [0003] Specifically, microcapsule technology refers to completely covering a certain object (core or inner phase) with various natural or synthetic polymer compound continuous films (wall or outer phase), while the original The chemical properties are not damaged at all, and then gradually through some external stimulation or slow release, the function of the target object is displayed outside again, or relying on the shielding effect of the capsule wall to protect the core material, the diameter of the microcapsule is generally 1 ~500μm, the thickness of the ...
