Abstract

The present invention relates to selenium-enriched beer. The content of selenium in the beer is from 0.016 to 0.200 milligram/kilogram. The preparation method of the selenium-enriched beer does not need to change the original preparation technology for beer. In the original preparation process flow, the step that sodium selenite is added is supplied, specifically, before main fermentation, when yeast paste is added, the sodium selenite with required weight is prepared into a water solution with the concentration of 0.2% to 0.5%, the water solution is added to a yeast paste bin, the water solution is pumped into a main fermentation tank along with the yeast paste, and under the biologic strengthening effect of yeast, the selenium-enriched beer is prepared. The weight (gram) of the sodium selenite to be added is determined according to the calculation of a formula: G=K. A. B, wherein A is the concentration (milligram/ kilogram) of selenium in beer, B is the gross weight (ton) of beer to be prepared, and K is a coefficient, and equals to 9.847.

Description

Selenium-enriched beer and production method thereof

The invention belongs to the technical field of adding trace element-selenium in the beer.

Trace element-selenium is since one of trace element of being confirmed as needed by human in 1973 by WHO expert committee, all the more, receive Chinese scholars and expert's concern in nearly 30 years, confirmed already, kind surplus human and scarce selenium diseases associated reaches 40, outstanding have cardiovascular and cerebrovascular diseases, cancerous swelling, hepatitis, diabetes, senile cataract or the like.The leading level in the world has been located in the research of China aspect selenium and Keshan disease (endemic cardiomyopathy), selenium and cancerous swelling, selenium and anti-ageing waiting for a long time.Selenium is present in each tissue of human body and the liquid, is the component of Selenoperoxidase, and its major function is to eliminate body endoperoxide and free radical (rubbish in the body), and the protection cytolemma is fulfiled normal physiological function.Therefore, human body lacks selenium can cause some important organ pipe functional disorder, causes the generation of multiple disease.

Selenium enters human body by food chain, that is to say that selenium is relevant with local food book on Chinese herbal medicine in the human body, and selenium content is few in local parent rock and the soil, and selenium content is also few in the food, causes scarce selenium so human body is taken the photograph the selenium deficiency.China has the some areas in 22 provinces, city to lack selenium, nearly hundred million people are in and lack the selenium state, as the Keshan lesion of Keshan County, northeast, the liver cancer district occurred frequently in Qidong, Jiangsu and large bowel cancer district occurred frequently of Zhejiang Jia Shanxian or the like, all relevant with scarce selenium in environment and food book on Chinese herbal medicine, these areas have all obtained control and have received good effect through the artificial selenium (medicine) of mending.At present, in the U.S. and other the countries concerned, when solving selenium deficiency problem, all adopt medicines such as oral administration of sodium selenite tablet or selenium yeast as mending the selenium approach.People for a long time, imagination will like in drink, nutritious beer forms selenium-enriched beer, but fails to find the ideal production technology always.

The present invention is not changing under original beer flavor and the manufacturing condition, adds a kind of additive technology, to produce the selenium-enriched beer that can satisfy the HUMAN HEALTH needs.The weight content of the selenium of this selenium-enriched beer is to contain selenium 0.016-0.200 milligram in 1 kilogram of beer.

Selenium-enriched beer production method of the present invention, be in original process for beer production flow process, to add the operation of adding Sodium Selenite together, when promptly before Primary Fermentation, adding yeast slurry, with the Sodium Selenite of required weight, be mixed with the aqueous solution of concentration with the sterilization aquae destillata in the 0.2-0.5% scope, add in the yeast hopper dredger, pump in the main fermentation tank in company with yeast slurry, under the biological reinforced effect of zymic, brewage 22 days after, can form selenium-enriched beer.

The Sodium Selenite of institute's expense in the inventive method, with require selenium-enriched beer in contain selenium concentration and produce the gross weight of selenium-enriched beer relevant, calculate by following relational expression and to determine:

G＝K·A·B

A is the weight content of selenium in the selenium-enriched beer in the formula, and unit is a milligram/kilogram;

B is the gross weight that requires to produce selenium-enriched beer, and unit is a ton;

K is a coefficient, value 9.847.

The mechanism of action of adding Sodium Selenite among the present invention is as follows: Sodium Selenite is under the biochemical action of cereuisiae fermentum, can transform to three aspects, form the selenium of different shape: (one) non-molten attitude organoselenium (albumen attitude selenium), in the brewage process, the Sodium Selenite of big part, utilized by the yeast cell self-reproduction, form the protein (seleno-protein) of yeast cell, be present in the yeast, this part selenium finishes with brewage, discharge with yeast slurry at last, its existence and beer selenium content relation are little; (2) soluble state organoselenium, in the brewage process, part Sodium Selenite, under the effect of yeast plurality of enzymes, form the selenide (as the amino-acid state selenide etc.) of part soluble state, these organic selenium are present among the beer, and are in close relations with the beer selenium content, it also is the main source (this part selenium also can become amino-acid state selenide etc. from self the decomposing of seleno-protein) of selenium in the selenium-enriched beer; (3) inorganic selenium, this is in the brewage process, a small amount of unemployed Sodium Selenite remains in the small portion in the beer, also is one of source of part selenium in the selenium-enriched beer.

Advantage of the present invention:

1, under the beer flavor permanence condition, contain the best selenium content of needed by human in the beer, for providing a kind of diet, people mend the new way of selenium diseases prevention;

2, needn't new investment increase process for beer production equipment, with low cost, easy to operate.

The embodiment of the invention:

Embodiment 1:

Scheme: produce 15 tons of selenium-enriched beers, require the beer selenium content to reach 0.025 milligram/kilogram.

1, weigh up required Sodium Selenite amount by calculating formula G=KAB,

G=9.847 * 0.025 * 15=3.693 gram

3, standby sodium selenite solution is all added in the yeast hopper dredger, pump in the main fermentation tank in company with yeast slurry;

4, can form selenium content through 22 days wine is

The selenium-enriched beer of (0.025 ± 0.005) mg/kg.

Embodiment 2:

Scheme: produce 15 tons of selenium-enriched beers, require the beer selenium content to reach 0.04 milligram/kilogram.

1, weighs up required Sodium Selenite amount by calculating formula G=KAB
