Additive for lactobacillus plantarum fermentation and preparation method thereof

Abstract

The invention discloses an additive for lactobacillus plantarum fermentation. The additive comprises a strain A, a strain B and a strain C. The strain A is prepared from the following raw materials in parts by weight: 7.5 g of yeast extract, 7.5 g of protein glands, 10g of glucose, 2g of monopotassium phosphate, 100mL of tomato juice and 20g of agar. The strain B is prepared from the following raw materials in parts by weight: 10g of peptone, 5g of liver extract powder, 3g of beef extract powder, 5g of yeast extract powder, 8g of tryptone, 0.5 g of soluble starch, 1g of sodium chloride, 1g of dipotassium phosphate, 1g of monopotassium phosphate, 10g of glucose, 0.01 g of FeSO4.7H2O, 0.005 g of MnSO4, 0.5 g of L-cysteine and 20g of agar. The additive is prepared by mixing the strain A, the strain B and the strain C, so that when the additive is fermented with the plant lactobacillus, the fermentation efficiency and speed are improved, the strain production speed is increased, the fermentation effect is better, and the strain survival rate of the lactobacillus plantarum can be better improved.

Description

technical field [0001] The invention relates to the technical field of additive processing, in particular to an additive for plant lactobacillus fermentation, in particular to an additive for plant lactobacillus fermentation and a preparation method thereof. Background technique [0002] Lactobacillus plantarum is a kind of lactic acid bacteria, the optimum growth temperature is 30~35°C, anaerobic or facultative anaerobic, the bacteria are straight or curved rod-shaped, single, sometimes in pairs or in chains, belonging to homofermentative lactic acid bacteria , Lactobacillus plantarum needs to go through the fermentation process during production, and additives need to be added to assist during fermentation. [0003] Existing additives for plant lactobacillus fermentation have certain deficiencies in use and need to be improved. At first, the existing additives for plant lactobacillus fermentation have poor fermentation effect on plant lactic acid sensation, fermentation is...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of additive that is used for plant lactobacillus fermentation, solves the traditional existing additive that is used for plant lactobacillus fermentation to the fermentation effect of plant lactic acid sensation is poor, fermentation is slow, and strain growth rate is slow; Secondly, the existing additives for the fermentation of plant lactobacillus all adopt the method of mixing raw materials to make additives, so that the survival rate of the strains is low when the plant lactobacilli are fermented, which is unfavorable for the technical problem of use; in the present invention, through the strain A. The additive made by mixing strain B and strain C has good anaerobic effect, so that when the additive is fermented with plant lactic acid bacteria, it can create an anaerobic environment for it, improve the fermentation efficiency and speed, and increase the production of strains Speed, better fermentation effect; inoculation of strain A, strain B and strain C in an environment of 30-37°C, and then fermented to make additives, which greatly improves the survival rate of the additives. When Lactobacillus plantarum is used for fermentation, it can better improve the survival rate of Lactobacillus plantarum
