Abstract

The present invention relates to a fermentation method, particularly to a method for produce monascus by using distillers' grain fermentation. The method specifically comprises the following steps: (1) preparing a distillers' grain saccharification liquid matrix: crushing dried distillers' grains to achieve 40-80 meshes, adding water to the crushed distillers' grains according to a weight ratio of the distillers' grains to the water of 1:10-20, uniformly mixing, heating to a temperature of 85-95 DEG C, adding alpha-amylase to carry out liquefaction for 20-30 min, cooling to a temperature of 55-65 DEG C, adding glucoamylase, and carrying out thermal insulation saccharification for 4-6 h to obtain a distillers' grain saccharification liquid; (2) preparing a solid state fermentation culture medium: adopting the distillers' grain saccharification liquid obtained from the step (1) to prepare a solid state fermentation culture medium, wherein the addition amount of the distillers' grain saccharification liquid is 15-32% of the total weight of the solid state fermentation culture medium; and (3) carrying out fermentation culture on monascus sp. The monascus prepared by using the method contains a plurality of physiological activity substances, further contains monascus pigment, ergosterol, gamma-aminobutyric acid and unsaturated fatty acids, and has a good health care effect, wherein amino acid content achieves 20%, and MonacolinK content can achieve 4-30 mg/g.

Description

technical field [0001] The invention relates to a fermentation method, in particular to a method for producing red yeast rice by fermenting distiller's grains. Background technique [0002] In 2011, the total output of my country's liquor industry increased by 30.7% year-on-year, reaching 10.256 million kiloliters. The rapid development of the liquor industry has driven the rapid development of liquor production capacity, but behind the rapid increase in production, the treatment of distiller's grains after production has become a difficult problem for enterprises. [0003] Now it is common to use distiller's grains directly as feed to feed livestock, in which a large amount of protein has not been transformed and is difficult to be absorbed and utilized, resulting in a lot of waste. It is also a common mode to use distiller's grains to make high-protein feed by full drying method, but the added value is low and the investment in equipment is large. Distiller's grains are ...
