High-yield monascus strain culture medium and preparation method thereof

Abstract

The invention discloses a high-yield monascus strain culture medium and a preparation method thereof. The high-yield monascus strain culture medium is prepared from the following raw materials in parts by weight: 10-15 parts of yam starch, 8-10 parts of taro starch, 3-5 parts of rice bran, 3-5 parts of cotton seed cake powder, 20-30 parts of ammonia water, 6-8 parts of soybean meal, 6-8 parts of pork bone peptone, 2-4 parts of magnesium sulfate, 2-4 parts of acidity regulator, 4-6 parts of compound amino acid, 10-12 parts of spinach liquid, 7-9 parts of JT compound bacteria liquid, 1-3 parts of disodium hydrogen phosphate, 1-3 parts of calcium chloride, 1-3 parts of vitamin A, 1-3 parts of vitamin C and 40-50 parts of distilled water. The culture medium does not agglomerate, has good heatdissipation performance and air permeability, is beneficial to the growth of monascus and the metabolism of monascus pigment, can accelerate the growth of a monascus strain and the metabolism of Monacolin K, and can effectively enhance the fermentation effect and product quality of functional monascus.

Description

technical field [0001] The invention relates to a high-yielding monascus strain culture medium and a preparation method thereof. Background technique [0002] Red yeast rice, also known as red yeast rice, is obtained by fermenting rice inoculated with Monascus. It is a great invention in ancient my country. It has a history of more than 1,000 years and has been used in food coloring, food fermentation, and traditional Chinese medicine for a long time. It is recorded in the "Compendium of Materia Medica" of the Ming Dynasty: "Red yeast rice is warm in nature and sweet in taste, promotes digestion and blood circulation, invigorates the spleen and drys the stomach. It makes wine, breaks blood and promotes medicine." In 1979, after the Japanese scholar Akira Endo discovered and isolated the active substance Monacolin K that can significantly inhibit the synthesis of cholesterol in the body from the fermentation broth of red yeast rice, people began to pay new and extensive atten...

AI Technical Summary

Problems solved by technology

[0004] At present, functional red yeast rice is traditionally fermented and cultivated using rice as a substrate, and oats, barley or yam are also used as substrates for cultivation. However, the nutrient composition of a single substrate is not completely suitable for the growth and The metabolism of monacolin K, and the existing powdery materials are likely to cause the solid medium to agglomerate during the fermentation process, which is not conducive to the heat dissipation and ventilation of the medium matrix, resulting in the existence of some raw materials after the fermentation. Monacolin K has the disadvantages of slow metabolism, low content in products, and low yield of Monascus strains
