Lactobacillus paracasei for degrading grease and application thereof

Abstract

The invention discloses lactobacillus paracasei F3 for degrading grease. The preservation number of the lactobacillus paracasei F3 is CGMCC No.18355. the lactobacillus paracasei F3 can degrade blend oil, peanut oil and sesame oil, the degradation effect on the sesame oil is the best, and the degradation rate is 39.38%. The strain can detect obvious lipase activity, and the enzyme activity is as high as 11.08 U/mL. Meanwhile, the lactobacillus paracasei F3 can degrade various fatty acids in the sesame oil, especially linoleic acid, oleic acid, trans-linoleic acid, palmitic acid, linolenic acidand other fatty acids, and the total degradation rate of the fatty acids in the sesame oil can reach 6.71 mg/mL. The lactobacillus paracasei F3 shows excellent acid tolerance and bile salt tolerance in tolerance experiments of artificial gastric juice, artificial intestinal juice and bile salt, can tolerate gastric juice and intestinal juice of a human body, can be used as probiotics with excellent performance, survives in intestinal tracts and plays a role. The lactobacillus paracasei F3 can be used as a food additive or directly prepared 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 which degrades 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 pancreatic lipas...
