Abstract

The invention discloses a preparing method of bifidobacteria bacterial active agent and single-purpose protecting agent, which is characterized by the following: allocating 0.01-5.0 wt glycerin, 0.1-6.0 wt polyvinyl pyrrolidon, 0.1-5.0 carbowax, 1.0-10.0 wt skimmed milk powder, 0.5-15.0 wt mycose, 0.1-5.0 wt glutavene, 0.1-5.0 wt L-aspartic acid, 0.1-5.0 wt vitamin C sodium and 0.1-5.0 wt ornithine hydrochlorate. This invention solves the problem of preservation difficulty at normal temperature with conventional method.

Description

technical field [0001] The invention relates to a live bifidobacterium preparation and a special protective agent thereof. Background technique [0002] Bifidobacterium (Lactobacillus bifidus) is a class of Gram-positive anaerobic bacteria, which is one of the most abundant and common normal flora in the intestinal tract of healthy people. In 1899, it was first isolated from the feces of healthy breastfed infants by Dr. Tissier of the Pasteur Institute in France. After more than 30 years of research, researchers from Japan and other countries, including European countries, gradually discovered the beneficial effects of bifidobacteria on the human body, and it has become a function of measuring the health of the body and evaluating the improvement of gastrointestinal flora. One of the symbols of sexual food. Bifidobacterium is the dominant bacterium in the gastrointestinal tract of healthy adults and long-lived elderly people. It changes dynamically with age and is closely ...
