Method for producing cordyceps sinensis feed additive and product

Abstract

The invention relates to a method for producing a cordyceps sinensis feed additive and a product, and belongs to the technical field of feed fermentation. The method comprises the following steps: firstly, quickly producing a large amount of mycelia through liquid fermentation by taking low-price beer dry yeasts and beer grains as raw materials; secondly, inoculating a large amount of mycelia into a solid culture medium for solid fermentation. According to the method, shallow tray type static and solid fermentation equipment is adopted for fermentation and is simple and convenient to operate, the fermentation cycle is short, the pollution is alleviated, the production cost is reduced, and the cordyceps sinensis mycelia can be efficiently produced to serve as the feed additive.

Description

technical field [0001] The invention relates to a method and a product for producing a feed additive for Cordyceps sinensis fungus, and belongs to the technical field of feed fermentation. Background technique [0002] Cordyceps sinensis, also known as "Cordyceps sinensis", is a precious Chinese medicine in the treasure house of medicine in my country, and its chemical composition is complex. Cordyceps contains 25.32% crude protein, 18.53% crude fiber, 28.9% carbohydrate, 8.4% fat, 4.1% ash, and 10.84% ​​moisture. Among them, cordycepin, nucleosides, amino acids, polypeptides, polysaccharides, sugar alcohols, sterols, fatty acids, esters, alkanes, polyamines, superoxide dismutase (SOD), amino acids, vitamins and various trace amounts Elements and other active ingredients have a variety of pharmacological and active functions, and have been reported to have anti-cancer, immune-enhancing, immune-regulating, blood-sugar-lowering and mRNA translation-inhibiting effects (Chen Gu...

Problems solved by technology

[0007] Selection of equipment: The solid-state fermentation of Cordyceps militaris is generally cultivated in shallow indoor trays, large outdoor beds and plastic bags. No complicated equipment is required. The production method is simple and easy, and the cost is low, but the production cycle is long, the pollution rate is high, and the quality is low and not good. Stable, if the traditional open solid-state tray fermentation is used, not only it is easy to cause bacterial contamination in the fermentation, but also the temperature, humidity and other cultivation conditions are difficult to control, the influence of temperature changes is great, and the product quality is inconsistent (Miao Wen et al., 1993), Therefore, it is difficult to meet the needs of commercial production and preparation processing, and the development of an automated and sealed solid-state fermentation device is the key to solving the above problems

When developing a solid-state fermentation tank, many aspects should be considered: (1) Compared with liquid submerged fermentation, the medium for solid-state fermentation has less water content and more gas phase, and the thermal conductivity of air is much lower than that of water. Therefore, The limiting factors of solid-state fermentation reactors include: oxygen mass transfer, temperature and solid medium water content, etc.

At present, my country's beer production ranks first in the world for many years in a row. The production has formed a group and large-scale production, but the effective ingredients have not been fully utilized, resulting in waste of resources and pollution of the environment.
