Preparation method and application of composite starter

Abstract

The invention discloses a preparation method and application of a composite starter. The preparation method comprises the following steps of: step 1, establishing a culture medium; step 2, separating and identifying lactic acid bacteria; step 3, screening excellent strains; step 4, preparing a microbial agent; and step 5, preparing the composite starter. Weissella mesenteroides cooperates with lactobacillus plantarum and lactobacillus brevis to form the composite starter for fermenting leaf mustard, so that the flavor of a product is improved, and the composite starter has a better potential application value; by using the composite starter, the fermentation period of the leaf mustard can be shortened, the fermentation end point can be reached in advance, the harm of infectious microbes is reduced, the defects of the fermented leaf mustard in taste and flavor can be regulated and controlled, the use is convenient, and the flavor and health trend of food development are met; and the composite starter can be directly put into the production of the leaf mustard, so that the product quality is improved, the use is convenient, and the key problems of long fermentation period, poor product quality stability, poor flavor and the like in the processing and production of the leaf mustard are solved.

Description

technical field [0001] The invention relates to the technical field of vegetable fermentation and processing, in particular to a method for preparing a composite starter and its application. Background technique [0002] At present, the common vegetable starter is single-strain fermentation, which can shorten the fermentation cycle and end the fermentation time in advance. , local flavor are single, therefore, need badly a kind of novel compound starter preparation method and application thereof at present stage. Contents of the invention [0003] The object of the present invention is to provide a kind of composite starter preparation method and application thereof, to solve the problems raised in the above-mentioned background technology. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for preparing a composite starter, comprising step 1, establishment of a culture medium; step 2, isolat...
