Lactobacillus paracasei having capacity for decomposing fat and application of lactobacillus paracasei

Abstract

The invention discloses lactobacillus paracasei F2. The preservation No. is CGMCC No.18354. The lactobacillus paracasei F2 can degrade blend oil, peanut oil and sesame oil, is good in effect of degradation on the peanut oil, and the degradation rate is 27.12%. The bacterial strain has obvious lipase activity, and the enzyme activity is as high as 5.88U / mL. Besides, the lactobacillus paracasei F2 can degrade various fatty acids in the peanut oil, particularly the fatty acid of linoleic acid, oleic acid, stearic acid, palmic acid, (Z)-gaidic acid, eicosenoic acid and the like. The total degradation rate of the fatty acids in the peanut oil can achieve 4.65mg / mL. The lactobacillus paracasei F2 presents excellent acid resistance and cholate resistance in the tolerance experiment of artificialgastric juice, artificial intestinal juice and cholate, can resist gastric juice and intestinal juice of human bodies, and can live and exert effects as probiotics being good in properties in intestinal tracts. The lactobacillus paracasei F2 can be used as food additives or directly made into foods, health-care products and the like.

Description

technical field [0001] The invention belongs to the technical field of lactic acid bacteria, and relates to a strain of Lactobacillus paracasei with the ability to decompose oil and its application. Background technique [0002] Dietary fat is an important source of energy for the human body and plays an important role in maintaining the energy balance of the human body. With the development of the economy, adequate food supply and other factors, dietary fat intake has increased significantly. Excessive dietary fat intake can promote the occurrence of chronic diseases such as obesity, coronary heart disease, diabetes and tumors. At present, the ways to reduce fat intake are mainly to change food cooking methods, reduce intake or use fat substitutes, etc. Although these methods can reduce fat intake to a certain extent, it is still difficult for people to resist the temptation of high-fat foods taste and flavor. [0003] After the fat is ingested, it mainly depends on the p...
