Method for making stabilized lactic acid bacteria product

Abstract

The invention discloses a method for making a stabilized lactic acid bacteria product. The method includes the steps of (1) preparing lactic acid bacterial fermentation liquor, (2) making enveloping materials, (3) carrying out in-situ enveloping, (4) carrying out lactic acid bacterial fermentation liquor separation, and (5) carrying out enveloping. By means of the method, in-situ enveloping is carried out after lactic acid bacteria are fermented, the pressure withstanding capacity and the shearing force withstanding capacity of the lactic acid bacteria are improved, damage, caused by post-processing, to bacteria bodies is reduced, and the activity of the lactic acid bacteria is kept; core particles are firstly made and then coated with the lactic acid bacteria, lactic acid bacteria particles are made, and influences of the high temperature and the pressure in the particle making process on the activity of the bacteria bodies are avoided. The lactic acid bacteria are enveloped through the composite materials, and it can be guaranteed that the bacteria bodies can smoothly pass through the stomach of an animal and are disintegrated and released under the effect of intestinal tract enzymes to play the probiotic role.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to a preparation method of a stabilized lactic acid bacteria product. Background technique [0002] The long-term use (especially abuse) of antibiotics as feed additives has caused widespread concern about the toxic residues and drug resistance. Scientists from all over the world are trying to find and develop new feed additives without toxic and side effects. Probiotics are the first new feed additives proposed. Compared with adding antibiotics, the use effect is the same, sometimes even better, without any toxicity, side effects, no residue in the body, and no drug resistance, so it soon became the focus of people's attention. [0003] With the vigorous development of green breeding, microecological preparations have been widely used in feed and livestock and poultry farming. Among them, lactic acid bacteria microecological preparations are the most widely used in feedin...
