Production method of compound multi-microorganism functional bacterium solution

Abstract

The invention discloses a production method of a compound multi-microorganism functional bacterium solution, and belongs to the technical field of wine brewing. The production method disclosed by the invention comprises the following steps: firstly, purely culturing various functional microorganisms respectively; secondly, carrying out secondary seed culture on the functional microorganisms and an aroma-producing yeast respectively; and then inoculating a secondary seed solution into each fermentation tank respectively, and producing the multi-microorganism functional bacterium mixed culture solution by regulating a fermentation culture medium and the fermentation conditions in phases. According to the production method disclosed by the invention, through a multi-microorganism mixed culture technology, production efficiency and equipment utilization rate are increased, a microorganism enzyme system as well as the types and contents of flavour substances are enriched, electricity consumption, water consumption and vapour consumption are saved, relative cost is reduced, and economic benefits are improved; the produced multi-microorganism functional bacterium solution is applied to the production of special flavouring liquor and special base liquor, provides an effective support for the production and blending of Yanghe 'soft-taste' wine with a unique style, and meets the production needs of the 'soft-taste' wine.

Description

technical field [0001] The invention relates to a production method of a composite multi-microfunctional bacterial liquid, which belongs to the technical field of brewing. Background technique [0002] The existing functional bacterial liquid production technology is usually single-strain culture, or mixed culture of a small number of strains according to type: on the one hand, a single strain cannot give full play to the performance of multi-micro-co-fermentation of wine-making functional bacteria; on the other hand, the process is cumbersome and equipment utilization Low yield, low medium conversion rate, long production cycle, and the enzyme system and flavor substances between the strains cannot effectively complement each other; the production method of the composite multi-micro functional bacterial liquid, using the principle of stage-by-stage control of the numerical control fermenter equipment, successfully Multi-strains of functional bacteria and multi-strains of fu...

[0002] The existing functional bacterial liquid production technology is usually single-strain culture, or mixed culture of a small number of strains according to type: on the one hand, a single strain cannot give full play to the performance of multi-micro-co-fermentation of wine-making functional bacteria; on the other hand, the process is cumbersome and equipment utilization Low yield, low medium conversion rate, long production cycle, and the enzyme system and flavor substances between the strains cannot effectively complement each other; the production method of the composite multi-micro functional bacterial liquid, using the principle of stage-by-stage control of the numerical control fermenter equipment, successfully Multi-strains of functional bacteria and multi-strains of functional yeast were compounded to achieve compound culture and co-fermentation of various types of functional bacteria. By making full use of modern fermentation technology and equipment, the enzyme system and flavor of compound multi-microfunctional bacteria were achieved. The effective complementation of substances fully exerts the performance of wine-making functional microorganisms
