Method for preparing flavor base material by double-strain synergistic fermentation of perilla meal

Abstract

The invention relates to a method for preparing a flavor base material by double-strain synergistic fermentation of perilla meal. The method comprises the following steps: (1) soaking in normal temperature water to make the perilla meal and bran completely immersed in water, draining off water of soaked raw materials after soaking for 0.5 to 1 hour, placing in an autoclave, carrying out cooking sterilization at the temperature of 121 DEG C for 20 to 30 minutes, when the materials are cooled to the room temperature, inoculating the double strains of Aspergillus niger and Aspergillus oryzae of which the inoculation amounts are 0.2 to 0.5%, and then fully and uniformly mixing the raw materials with the double strains; (2) putting the inoculated leaven materials in a constant-temperature ventilation incubator to be cultured, turning the leaven materials for two times during the culture process, and culturing for 24 to 48 hours to obtain the finished leaven materials, putting the prepared leaven materials in a fermentation tank, adding saline water and fermenting; (3) after the fermentation is finished, filtering to obtain the flavor base material. The flavor base material prepared by fermentation is natural in flavor and coordinated, fine and smooth and mellow and full-bodied in taste.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a method for synergistically fermenting perilla dregs with dual strains of Aspergillus oryzae and Aspergillus niger to prepare flavor base material. Background technique [0002] Perilla meal is the main by-product after perilla seed oil is extracted from perilla seeds, which is the oil-pressing residue. The perilla meal contains vegetable protein, and the protein content in the degreased meal is 28% to 45%, which is relatively high and has no toxic or harmful substances, and contains various active ingredients beneficial to human health. Compared with foreign countries, the utilization of perilla meal in my country is still in its infancy, so it is necessary to increase investment in the development of perilla meal reuse and deep processing.

Problems solved by technology

[0003] Microbial fermentation is the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions; fermentation as a preservation technology has been used in many countries, but with the development of various preservation technologies (such as freezing, drying or canning, etc.), and now people are slowly shifting their attention from preservation to the flavor of the product obtained after fermentation
