Description

Technical Field

[0001] The invention belongs to the technical field of winemaking, and particularly relates to pure-grain selenium-enriched wine and a preparation method thereof. Background Art

[0002] Selenium is an essential trace element for the human body. It is an indispensable trace nutrient for the human body. It participates in the formation of many enzymes, especially glutathione peroxidase, which can protect cells and tissues and maintain their normal functions. Selenium has strong antioxidant and harmful free radical removal functions. Selenium also has detoxification effects because selenium has a good affinity with metals. Selenium has the function of protecting cardiovascular and cerebrovascular and liver. Selenium is the natural enemy of liver disease. Selenium also has the world-recognized anti-tumor and anti-cancer effects. It also has a regulatory effect on thyroid hormones, which can maintain and improve immune function; it also has anti-AIDS effects; it can maintain normal reproductive function, etc.

[0003] Selenium sources include: (1) all organic selenium (including plant organic selenium, quantum selenium, nano selenium, and selenium sources with organic selenium content greater than 80% of the total selenium content). (2) semi-organic selenium (including yeast selenium, malt selenium, fungus selenium, fungus selenium and other organic selenium sources that can be absorbed and utilized by the human body).

[0004] The form and utilization of selenium sources: (1) Selenium sources exist in the form of methylselenocysteine, which is recognized as the safest organic selenium source in the world. (2) All organic selenium that can be absorbed by the human body is converted into cysteine ​​by glutathione peroxidase before it can be absorbed and utilized.

[0005] Because of the important role of selenium in human health, the country has elevated the functional selenium-rich industry to the national strategic level in recent years. There are many selenium-rich products on the market, such as selenium-rich rice, selenium-rich tea, selenium-rich eggs, etc. These selenium-rich products have entered people's healthy diet life.

[0006] Wine is a national specialty of China's thousand-year-old culture. my country's unique winemaking technology has become a typical representative and model of the oriental brewing industry. Selenium-rich wine refers to a drink that contains a large amount of selenium. Now more and more wine manufacturers and research institutions have begun to develop and research selenium-rich wine, hoping that the wine contains selenium, which not only has a better taste, but also has higher nutritional value.

[0007] However, due to the immature preparation process of selenium-enriched wine, the types, characteristics, values, and proportions of selenium sources are also immature, resulting in low selenium content and poor stability of selenium-enriched wine, which results in large deviations in the quality, taste, and selenium content of selenium-enriched wine, and the loss of the nutritional value that the selenium content in selenium-enriched wine must have a corresponding nutritionally stable value. Therefore, the development of a production method for pure grain selenium-enriched wine has become a problem that needs to be solved at present.

[0008] The disadvantage of the selenium-enriched wine in the prior art is that it can only produce selenium-enriched fruit wine, selenium-enriched beer and selenium-enriched low-alcohol wine with a low selenium content. The selenium content in the produced wine is all below 100 micrograms / kg, and the selenium sources used are all organic selenium or semi-organic selenium, such as organic selenium sources and semi-organic selenium with a selenium content of about 80%.

[0009] For example, the patent application with application number: 202410889396.3 discloses a selenium-enriched beer production process, which includes the following specific steps: S1. Organic selenium preparation: yeast is cultured in a culture medium containing sodium selenite. The yeast will convert sodium selenite into selenomethionine and selenocystine organic selenium, which will eventually be enriched in the yeast body to obtain selenium-enriched yeast body; S2. Material preparation: Select high-quality barley with malt saccharification ability, fermentation performance, chromaticity and protein content and soak it in the previously prepared solution prepared with organic selenium, RO water or reverse osmosis water, select fresh and high-quality hops and selenium-enriched beer yeast. By preparing organic selenium separately and culturing selenium yeast body with organic selenium, the selenium yeast body is mixed with water to obtain water rich in selenium, and the barley is soaked in selenium-rich water to obtain selenium-enriched malt, avoiding the use of yeast to convert inorganic selenium into organic selenium and produce toxic selenium compounds, thereby ensuring the safety of the product.
