Application of plants lactobacillus in fresh-keeping of freezing meat

Abstract

The invention provides the application of lactobacillus in frozen meat preservation and simultaneously provides a new bacterial strain A71 of Lactobacillus plantarum with a preservation number of CGMCC No.2228. The bacterial strain has an excellent culturing characteristic, a fermenting liquid of the bacterial strain has an excellent bacterial restraining capacity and can be used in the field of food preservation, in particular to the frozen meat preservation.

Description

technical field [0001] The invention belongs to the field of food preservation, and in particular relates to the application of plantarum lactobacillus in preservation of frozen meat. Background technique [0002] Lactic acid bacteria (LAB) is a general term for bacteria that can ferment sugar and produce large amounts of lactic acid. Lactic acid bacteria are widely distributed in nature and are the dominant bacteria in the normal intestinal flora of humans and animals. They not only have many physiological functions beneficial to the health of humans and animals, but also can produce organic acids (such as lactic acid, butyric acid and acetic acid, etc.), Bacteriostatic substances such as hydrogen peroxide and bacteriocins (Yang Jiebin and Ge Xinghua, 1996). These antibacterial substances not only have a good effect on maintaining the flavor and tissue state of food, but also can inhibit the growth of spoilage bacteria and pathogenic bacteria, thereby preventing spoilage a...
