Description
Technical Field
The invention relates to the technical field of ceramic products, in particular to a selenium-rich ceramic wine bottle and a preparation method thereof.
Background
The traditional wine bottle generally takes glass as a raw material and has the defects of high firing temperature and high energy consumption, so that the wine is usually packaged by adopting a ceramic wine bottle at present. On one hand, the light-tight characteristic of the ceramic wine bottle can prevent the white spirit from generating chemical reaction due to illumination, and the quality of the white spirit is ensured; on the other hand, the ceramic wine bottle has slower heat conduction than the glass wine bottle, can ensure the wine temperature and avoid the white wine from deteriorating in low-temperature or high-temperature environment. However, the ceramic wine bottle has the defects of long firing period (more than 12 h), high firing temperature (more than 1280 ℃) and high energy consumption, and is not beneficial to the production of the ceramic wine bottle and the development of the industry.
Medical research shows that selenium is one of essential trace elements for human body, has multiple functions of resisting cancer, resisting aging and oxidation, enhancing human immunity, regulating the absorption and utilization of vitamins, regulating the synthesis of protein, enhancing the fertility function and the like, and is also an important component of muscle function. However, selenium cannot be synthesized in human body, and is required to be taken in by the outside, and insufficient selenium intake can cause diseases such as liver cancer, lung cancer, gastric cancer, esophageal cancer, bladder cancer, hepatitis, eye diseases, cardiovascular and cerebrovascular diseases, osteoarthritis and the like.
Chinese patent No. 97101549.X describes a production process of selenium-enriched beer, which is characterized by adding a step of adding sodium selenite into the original production process, specifically, when yeast paste is added before main fermentation, the required weight of sodium selenite is prepared into 0.2-0.5% concentration aqueous solution, and the aqueous solution is added into a yeast paste storehouse and pumped into a main fermentation tank along with the yeast paste, and the selenium-enriched beer is brewed under the biological strengthening action of yeast. The weight (g) of sodium selenite added is determined by the following formula: g = K A B, wherein A is the selenium content concentration (microgram/kilogram) in the beer; b is the total weight (ton) of beer required to be produced, and K is a coefficient of 9.847.
However, the production process of the selenium-enriched beer in the patent has many disadvantages: (1) Sodium selenite is added before fermentation, and great loss is caused along with the precipitation of the selenium-enriched yeast; (2) The amount of sodium selenite entering the finished beer during the fermentation process is not easy to control, the addition amount is difficult to be accurate, and if the addition amount is too high, the selenium content in the beer is possibly overproof and the health of human bodies is damaged; (3) Selenium affects the fermentation process of beer and tastes bad.

TABLE 1
| Sample (I) | Winebottle powder selenium content (mg/kg) | Selenium content of Chinese liquor (mg/kg) |
| Example 1 | 3.5 | 0.043 |
| Example 2 | 3.3 | 0.04 |
| Example 3 | 4.9 | 0.064 |
| Example 4 | 2.1 | 0.024 |

| Comparative example 4 | 3.3 | 1.2 |
As shown in table 1, the results of the selenium content test of the wine bottles of examples 1 and 2 are equivalent, and the results of the selenium content test of the white spirit are equivalent, and the difference between the examples 1 and 2 is that kaolin or purple clay is selected as the pottery clay, and as can be seen from the results of the test of table 1, the selection of the pottery clay has little influence on the selenium content of the ceramic wine bottles and the selenium dissolving capacity of the wine bottles; the selenium content of the wine bottle and the selenium content of the white spirit in the embodiments 1, 3 and 4 are in a linear relation with the content of the wulan tea spar in the embodiments, and it can be shown that when the fineness of the wulan tea spar powder is between 40 and 80 meshes, the content of selenium in the wine bottle is increased along with the increase of the content of wulan tea spar, and further the content of selenium in the white spirit is increased, and the selenium dissolving capacity of the wine bottle is irrelevant to the content of the wulan tea spar because of the linear relation; comparing example 1 with comparative example 1 and comparing example 2 with comparative example 2, it can be known that the common wine bottle without wulan tea crystalloid has extremely low selenium content, and the white wine basically does not contain selenium element, and can not provide the selenium element required by human body; as can be seen from the comparison between the example 1 and the comparative example 3, the fineness of the wulan tea crystal stone powder is too low, the wulan tea crystal stone powder is wrapped by the coal gangue and the kaolin, and the selenium dissolving capacity of the white spirit is reduced, so that the content of selenium in the white spirit is lower; and the comparison of the strength 1 and the comparative example 4 shows that the Wulan tea crystal stone powder has too high fineness and is displayed on the surface of a ceramic wine bottle in a large amount, selenium is easily dissolved in the white wine, so that the selenium content in the white wine is too high, and people are easily subjected to selenium poisoning caused by excessive intake of the selenium when drinking the white wine.
