Selenium-enriched Cordyceps fungus and cultivation method thereof, selenium-enriched rice wine and preparation method thereof

Abstract

The invention provides a culture method of selenium-enriched cordyceps sinensis. According to the culture method, selenium-enriched culture of cordyceps sinensis is carried out by adopting a manner of adding inorganic selenium twice in the fermentation culture process of cordyceps sinensis, by defining the two-time adding time and adding amount of inorganic selenium, the limiting bottleneck of the toxicity of inorganic selenium for the selenium amount is solved, thus the selenium content of cordyceps sinensis is obviously improved, and therefore, organic selenium enriched cordyceps sinensis is obtained. In addition, the intention further provides a preparation method of selenium-enriched yellow rice wine; according to the preparation method of the selenium-enriched yellow rice wine, organic selenium enriched cordyceps sinensis is compounded with Chinese-dates and Chinese wolfberry fruits to prepare compound cordyceps sinensis nutrient solution, the obtained compound cordyceps sinensis nutrient solution is mixed with cooked milled glutinous broomcorn millets, through the traditional brewing technology of yellow rice wine, the selenium-enriched cordyceps sinensis health wine which is orange-yellow in color, is clear and transparent, has gloss, and has coordinated aroma is brewed, and the obtained wine body is full and coordinated, mellow and refreshing, has the typical aroma of yellow rice wine and cordyceps sinensis, and also has the nutrition and efficacies of cordyceps sinensis and organic selenium, thus being the novel selenium-enriched yellow rice wine with the health care function.

Description

technical field [0001] The invention relates to the technical field of selenium enrichment, in particular to a selenium-enriched Cordyceps fungus and a method for cultivating the selenium-enriched Cordyceps fungus, and also relates to a selenium-enriched rice wine prepared from the selenium-enriched Cordyceps fungus and a preparation method. Background technique [0002] Selenium (Se) is one of the trace elements necessary for human and animal life activities. It exists mostly in the liver, kidney, pancreas, heart, spleen, tooth enamel and nails of the human body. Selenium exists in nature as inorganic selenium and organic selenium. Inorganic selenium is highly toxic and has certain toxic effects on animal, plant and microbial cells. Therefore, the selenium usually supplemented in food exists in the form of organic selenium. At present, organic selenium is mostly obtained by biotransformation. [0003] Cordyceps sinensis (Cordyceps sinensis), also known as Chinese caterpilla...

Problems solved by technology

However, due to the shortage of sources of Cordyceps medicine and the high price, it is far from meeting the needs of domestic and foreign markets. In recent years, people have obtained artificial Cordyceps fungi by fermentation of natural Cordyceps fungi, and studies have proved that artificial Cordyceps has similar chemical properties to natural Cordyceps sinensis. Composition, pharmacological action and clinical efficacy, and the toxicity is less than natural ones, so Cordyceps and related products have been continuously developed, such as Cordyceps fermented preparations, Cordyceps fermented wine, etc.

[0004] The biotransformation and enrichment of Se-enriched Cordyceps fungus by using Cordyceps fermented liquid is of great significance for the development of Cordyceps functional food and medicine, but due to the toxicity of inorganic Se, the addition of inorganic Se If the amount of inorganic selenium exceeds, it will inhibit or poison the mycelium, slow down or stop the growth of mycelia, thus limiting the content of organic selenium in the mycelium and affecting the functional performance of selenium
