Culture medium applied to monascus fermenting yeast seed, culturing method of culture medium and preparing method of monascus vinegar

Abstract

The invention relates to the technical field of microbial fermentation, in particular to a culture medium applied to a monascus fermenting yeast seed, a culturing method of the culture medium and a preparing method of monascus vinegar. The culture medium is prepared from a basic culture medium body, a carbon source, a nitrogen source, a growing factor and inorganic salt. The culturing method comprises the steps of taking the basic culture medium body, adding the carbon source, the nitrogen source, the growing factor and the inorganic salt into the basic culture medium body, inoculating monascus spore suspension, adjusting an initial pH value as 4-8 and shaking and culturing to obtain the monascus fermenting yeast seed. The preparing method of the monascus vinegar comprises the following steps of preparing the monascus fermenting yeast seed, saccharifying, fermenting, filtering and sterilizing. The culture medium applied to the monascus fermenting yeast seed, the culturing method of the culture medium and the preparing method of the monascus vinegar are different from an existing culturing method of the culture medium and an existing preparing method of the monascus vinegar. Screening the optimal culture medium and producing the functional monascus vinegar through a solid-liquid fermenting method are innovation and development of the vinegar industry.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a culture medium for monascus fermented koji species, a cultivation method thereof and a preparation method of red koji vinegar. Background technique [0002] Monascus is a filamentous fungus with traditional Chinese characteristics. There are many types of metabolites, and the main focus is on polyketide secondary metabolites. Recent studies have shown that Monascus can also produce biologically active substances that are beneficial to human health. Therefore, Monascus and its products may become food ingredients, additives and new drugs for anti-lipid and blood pressure with health functions. Because of its certain active functions, more and more medical studies in recent years have shown that Monascus plays a very important role in the protection of human health such as obesity, coronary heart disease, hypertension, arteriosclerosis and other cardiovascular dise...

Problems solved by technology

[0004] At present, red yeast rice vinegar is mostly produced by the traditional split liquid shallow fermentation process, which generally has a series of problems such as irregular operation, difficulty in industrialization, unstable quality, and backward production technology. The traditional production of old vinegar uses natural microorganisms including Harmful microorganisms, the safety of the product is also widely questioned, the quality has been unstable for a long time, and large-scale production and preparation cannot be effectively realized
