Embodiment 1

[0041] 1. Select 1000g of glutinous rice, which requires full grains, bright white color, no moldy rice, no miscellaneous rice, and no broken rice.

[0042] 2. Rice soaking: add 1000g of pure water, and soak the rice for 9 hours. The rice soaking time varies with different temperatures.

[0043] 3. Rice washing: Wash the soaked glutinous rice until the white matter in the water is significantly reduced and the rice grains can be seen clearly without hindrance.

[0044] 4. Steam rice: Use the steam in the steamer to steam the rice for 30 minutes. Steamed rice has loose grains, crystal clear, moderate hardness and chewy texture.

[0045] 5. Drenching: When the temperature of the rice grains drops to 28°C to 30°C, use 800g of cold water at about 30°C to shower.

[0046] 6. Mix koji: Mix Rhizopus Q303 koji evenly into the cooled rice, add 13g Rhizopus koji, and mix well.

[0047] 7. Putting into the tank: put the mixed koji rice into the tank, build a nest, and put it into the ...

[0055] 3. Rice washing: Wash the soaked glutinous rice until the white matter in the water is significantly reduced and the rice grains can be seen clearly without hindrance.

[0056]4. Steam rice: Use the steam in the steamer to steam the rice for 30 minutes. Steamed rice has loose grains, crystal clear, moderate hardness and chewy texture.

[0057] 5. Drenching: When the temperature of the rice grains drops to 28°C to 30°C, use 800g of cold water at about 30°C to shower.

[0058] 6. Mix koji: Mix Rhizopus Q303 koji evenly into the cooled rice, add 13g Rhizopus koji, and mix well.

Abstract

The invention discloses a preparation method of selenium-rich rice wine. Common sticky rice is used as a main raw material, a saccharification process and a fermentation process are separately carriedout on the basis of a common sweet wine making process, and selenium-enriched yeast is added in the fermentation process for fermentation. The rhizopus Q303 distiller's yeast accounting for 1.3% of the mass of the dry sticky rice is used for saccharification, and the saccharification time is 17 h; 0.15%-0.7% of selenium-enriched yeast, 9% of cane sugar and 100% of cold boiled water are used for mixed fermentation, and the fermentation time is 26-30 h; the fermented rice wine is sterilized at 75 DEG C for 30 minutes, and the sterilized rice wine is stored at a low-temperature dark place in a sealing manner. The total selenium content of the obtained rice wine can reach 41.3-362 [mu]g / 100g. The selenium-enriched yeast can be applied to research and development of selenium-supplementing sweet wine and selenium-supplementing medicines by adjusting the addition amount and the fermentation time of the selenium-enriched yeast.

Description

Technical field: [0001] The invention belongs to the field of food processing, and in particular relates to a method for preparing selenium-enriched rice wine. Background technique: [0002] Rice wine, also known as fermented glutinous rice, fermented glutinous rice, etc., is one of the traditional specialties in southern my country. It is a low-alcohol beverage made from glutinous rice and fermented through a series of processes. Because of its rich nutrition and mellow taste, it is deeply loved by consumers. [0003] As one of the essential trace elements for the human body, selenium has important functions in preventing cancer, protecting cardiovascular and cerebrovascular, delaying aging and other aspects of human health. Selenium can activate immunoglobulins in the human body, increase antibodies, and thus improve human immunity. Therefore, selenium plays an irreplaceable role in the vital activities and health of the human body. [0004] Selenium-enriched yeast is t...
