Selenium-rich monascus production method

Abstract

The present invention relates to a fermentation method, particularly to a selenium-rich monascus production method, which comprises the following steps: (1) preparing a selenium-rich yeast mycelium matrix: mixing a selenium-containing compound and malt wort to prepare a yeast liquid state fermentation culture medium, inoculating a yeast strain into the culture medium, culturing for 30-35 h at a temperature of 30-35 DEG C, carrying out centrifugation to obtain a solid, drying at a temperature of 40-60 DEG C, and crushing to obtain selenium-rich yeast mycelium; (2) preparing a solid state fermentation culture medium: adopting the selenium-rich yeast mycelium obtained from the step (1) to prepare a solid state fermentation culture medium, bottling, sterilizing, and scattering the solid state fermentation culture medium material in the bottle while hot; and (3) carrying out fermentation culture on monascus sp. The monascus obtained through fermentation contains a plurality of physiological activity substances and has a good health care effect, wherein selenium content is more than 300 mug / g, protein content is more than 60%, and MonacolinK content can be 4-30 mg / g.

Description

technical field [0001] The invention relates to a fermentation method, in particular to a preparation method of selenium-enriched red yeast rice. Background technique [0002] Monascus is a mixture of Monascus mycelium obtained by inoculating Monascus on rice (or starchy items) and culture substrate (usually rice). Red yeast rice is not only a traditional Chinese medicine, but also a food. It has been widely used as food coloring agent, flavoring agent, raw material for making red bean curd, meat preservative and medicine in China throughout the ages. [0003] Since Japanese scholars discovered the lipid-lowering active substance Monacolin K (Monacolin K) in red yeast rice in 1979, many scholars and experts at home and abroad have conducted extensive and in-depth research on the active ingredients of red yeast rice, and applied the research results to In various fields such as food and medicine, the field of functional red yeast rice has gradually formed, which has achieved...

Problems solved by technology

[0006] At present, most red yeast rice is a functional red yeast rice containing Monacolin K that has been solid-state fermented with rice as a medium. The approach to a synergistic effect has not been reported

[0007] Among them, the Chinese patent with the application number CN 1272368A discloses "a selenium-enriched red yeast rice for lowering blood lipid and blood sugar". Carrying out the conversion of selenium, though can play certain selenium-enriching effect, still has several deficiencies: 1. take selenium-enriched grain as fermentation raw material, will certainly increase input, and the conversion amount of selenium in the product is subject to the selenium content in the raw material limit
