Selenium-rich rice wine production method

Abstract

The invention provides a selenium-rich rice wine production method. The method includes: (1) adding selenium-rich glutinous rice (selenium content is 0.322mg / kg), purplish glutinous rice, red glutinous rice and wheat koji according to a proportion of 75:11:6:8; (2) soaking: strictly controlling the water temperature to range from 10 DEG C to 15 DEG C and soaking for 7-10 days; (3) steaming: flushing the soaked rice, removing broken and rot rice and guaranteeing that the scour flavor is not washed away completely; (4) jar filling: when the room temperature is 10-15 DEG C, the jar filling temperature is 26-28 DEG C, and if the room temperature is lower than 10 DEG C, the jar filling temperature is strictly controlled to range from 29 DEG C to 31 DEG C; (5) pre-fermentation: enabling the internal fermentation temperature in jars to reach 34-35 DEG C within 40-44 hours after jar filling, timely stopping heat preservation measures, harrowing for cooling and ventilating for the first time, and constantly keeping the fermentation temperature to be 32-35 DEG C; (6) after-fermentation; (7) extracting; (8) boiling; (9) packaging; (10) examination. The selenium-rich rice wine production method has the advantages that selenium loss in production is greatly avoided, uniformity in steaming is achieved, subsequent fermentation is guaranteed, and selenium-rich rice wine produced according to the method is rich in nutrient and better to taste.

Description

technical field [0001] The invention relates to a production method of selenium-enriched rice wine. Background technique [0002] Yellow rice wine is a national specialty of China, and its brewing technology is unique, which has become a typical representative and model of the oriental brewing industry. Rice wine contains polyphenols, melanoidin, glutathione and other physiologically active ingredients, which have physiological functions such as scavenging free radicals, preventing cardiovascular diseases, anti-cancer, and anti-aging. 18 kinds of inorganic salts have been detected, including calcium, magnesium, potassium, phosphorus, iron, zinc, etc. The content of vitamin B and E in rice wine is also very rich, mainly from raw materials and yeast autolysate. [0003] Selenium is a trace element needed by the human body. It is an indispensable element for the human body. It participates in the formation of many enzymes, especially glutathione peroxidase, which can prote...

Problems solved by technology

[0004] At present, there are many selenium-enriched products on the market, such as selenium-enriched rice. At present, when selenium-enriched rice is used to brew yellow rice wine, due to the immature process, a large amount of selenium is lost during soaking, and the amount of steamed rice, the amount of water, and the speed of watering Control the impact on selenium loss; and poor fermentation will also affect the taste, because a small amount of broken rice has been soaked and gelatinized and sour after soaking. Direct cooking will cause uneven steaming due to uneven ventilation of the rice layer, which will affect the later stage. fermentation control
