Process for preparing water-soluble hypolipemic monascin

Abstract

A water-soluble hypolipemic monoscin is prepared through preparing a medium from potato juice, sugar, yeast, rice flour, MgSO4.H2O, KNO3, CaSO4 and KH2 PO4 as raw amterial, fermenting by Monascus purpureus as initiating strain, then filtering, heating, and concentrating to obtain the solid product. Its advantages are high hypelipemic effect, low by-effect, high water solubility and low cost. It can be used to treat leukermia and cardiovascular and cerebrovascular diseases.

Description

technical field [0001] The invention relates to a method for preparing monascus pigment by microbial fermentation, in particular to a method for preparing water-soluble lipid-lowering monascus pigment. Background technique [0002] Existing food pigments are divided into two categories: synthetic pigments and natural pigments. The raw materials of synthetic pigments come from tar series products, or are synthesized from substances such as benzene rings or naphthalene rings in coal tar, and the chemical components directly damage physical and mental health. The use has been gradually restricted, and the edible natural pigments extracted from animals, plants and microorganisms, which are non-toxic and edible and harmless to human health, are welcomed by people and society. Monascus pigment is the pigment produced by the fermentation of Monascus. The traditional red yeast rice technology in my country is to make red yeast rice into solid rice by inoculating it on indica rice a...

Another example is Japanese Patent No. 57-190050. In order to improve the color value, select the medium containing maltitol, which can make the total color value of the fermented liquid reach the level of 110-120U / ml, and then add magnesium aspartate to the fermentation medium containing maltose. In the culture medium, the total color value of the fermentation broth reaches the level of 248U / ml. Because the price of maltose and magnesium aspartate is very expensive, the cost of the red yeast pigment produced by this method is too high

Since the biggest disadvantage of Monascus pigment is its poor stability to light and heat, in order to solve this problem, Japanese Patent No. 52-13527 uses the protein isoelectric point method to precipitate the pigment, but the effect is still unsatisfactory

Chinese patent 85103584 discloses the "Manufacturing Method of High Stability Monascus Pigment". M130 Monascus Monascus is selected, and after fermentation, protein isoelectric point method is used to precipitate protein Monascus Pigment powder, and polysaccharide is added to make Monascus Pigment Polysaccharide Tablets , but the process is long and the water solubility of the product is not good
