Preparation method of Chinese-date probiotics tablet of lactobacillus paracasei capable of producing bile salt hydrolase

Abstract

The invention relates to a preparation method of a Chinese-date probiotics tablet of lactobacillus paracasei capable of producing bile salt hydrolase. The preparation method is suitable for producing microecological preparations such as a functional probiotic lactic bacteria living bacteria agent. A formula of the Chinese-date probiotics tablet consists of lactobacillus paracasei KL1-Liu probiotics bacterial powder and auxiliary materials such as Chinese-date powder, fructo-oligosaccharide, xylitol, sucrose, citric acid, microcrystalline cellulose and maltodextrin. The preparation method of the Chinese-date probiotics tablet comprises the following steps: preparing the probiotics bacterial powder from lactobacillus paracasei KL1-Liu CGMCC No.7029 capable of producing the bile salt hydrolase by virtue of processes such as activating, performing enlarged culture, performing high-density fermentation, performing centrifugal concentration, adding a freeze-drying protective additive, pre-freezing, and freeze-drying; mixing the crushed and screened auxiliary materials with the probiotics bacterial powder, thereby obtaining a mixture, and then pressing the mixture into the Chinese-date probiotics tablet. The Chinese-date probiotics tablet prepared by the preparation method disclosed by the invention has good storage stability and a refrigeration living bacteria quality guarantee period of over one year at 4 DEG C, not only can bring the health effects of lowering the serum cholesterol of the products into play, but also can bring the medicinal and edible nutritional and health effects of Chinese-dates into play. Moreover, the preparation method of the Chinese-date probiotics tablet disclosed by the invention has a convenient raw material source, a simple process, a short preparation period and simple operation, and is suitable for industrial production.
