Problems solved by technology

However, during the production of red yeast rice, a large amount of mycelium waste residue will be produced. According to statistics, 2.3-2.5 tons of fungal residue will be produced for every ton of red yeast rice produced. These fungal residues are generally used as feed, and the price is low, which is a great waste of resources.
[0004] Wu Tie from Guangdong Medical College used acid or alkali to treat and extract the discarded Monascus mycelium, which caused secondary pollution and was unfavorable to the environment. Moreover, the product obtained by acid hydrolysis contained more salt, high impurity content, and low purity.
The applicant analyzed many batches of red yeast slag produced and found that the main components are mycelia and solids, of which the protein content is 38-40%, the ash content is 4%, the color value is above 300, and basically does not contain lovastatin Components, if not fully utilized, will cause a great waste of resources, which is not conducive to environmental protection
In this field, there has never been a report on the treatment of Monascus slag by ultrasonic synergistic compound enzymatic hydrolysis

Embodiment 1

[0035] A method for processing Monascus slag, the steps are as follows:

[0036] (1) Ultrasonic crushing step of Monascus mycelium

[0037] Pulverize the mycelium of Monascus koji through a 100-mesh sieve, soak in water, soak for 2-3 hours according to the ratio of solid to liquid in the mass-to-volume ratio of 1:10, and perform ultrasonic crushing. The ultrasonic power is 120-160W, and the treatment temperature is 30-50°C. Time 1-2h;

[0038] Described red yeast mycelium is prepared by following method:

[0039] After the rice and peptone are submerged with Monascus for 7 to 10 days, the liquid product fermented by Monascus is pressed out by a press, and then the red pigment is extracted with ethanol with a mass concentration of 60-70%. Monascus mycelium with red pigment, dried and stored at room temperature, wherein Monascus was preserved by the General Microorganism Center of China Committee for the Collection of Microorganisms, and the number was CGMCCNo.6807 Monascus s...

Abstract

The invention belongs to the technical field of monascus residue waste utilization, and specifically discloses a method for treating monascus residue, namely a method for preparing health-care food for reducing blood fat, reducing blood pressure and preventing osteoporosis by enzymolysis of monascus residue. The monascus residue left after monascus pigment is produced is treated by ultrasonic wave and composite enzymolysis, mycelia are crushed to release protein and polysaccharides therein, then the monascus residue is degraded into protein polypeptide or amino acid, residual active substances such as ergosterol and gamma-aminobutyric acid are enriched, and the monascus residue can be prepared into a microcapsule preparation for reducing blood fat, reducing blood pressure and preventing osteoporosis, so that secondary pollution in the traditional acid-alkali treatment process is avoided.

Description

technical field [0001] The invention belongs to the technical field of waste utilization of monascus slag, and specifically relates to a method for treating monascus slag, which uses the enzymatic hydrolysis of the monascus slag to prepare health food for lowering blood fat, lowering blood pressure and preventing osteoporosis. Background technique [0002] In recent years, with people's understanding of the toxic and side effects of synthetic food additives and chemical drugs on the human body, countries all over the world have set off an upsurge in eating green food and using natural medicines. s concern. According to traditional Chinese medicine, red yeast rice is sweet and warm in nature, and has the effect of regulating blood lipid concentration and slowing down cardiovascular diseases. Monascus spp. is the main strain for the production of red koji wine, red koji rice, functional red koji and natural pigments. In 1979, Japanese scholar Akira Endo first discovered the ...
