Embodiment 1

[0028] Embodiment 1 different assimilable nitrogen source addition amount

[0029] The rice wine brewing method for reducing the content of higher alcohols in rice wine with different additions of assimilable nitrogen sources comprises the following steps:

[0030] (1) Soaking rice: Soak glutinous rice in water, the ratio of material to water is 1:0.9-1:2.3, and the soaking time does not exceed 24 hours;

[0031] (2) Steamed rice: Rinse the soaked glutinous rice and cook until soft and rotten without white heart;

[0032] (3) Drain the rice: rinse the steamed glutinous rice with water, cool and drain;

[0033] (4) Putting into the tank: Transfer the glutinous rice after pouring rice into the brewing tank, add water and mix according to the material-to-water ratio of 1:0.9-1:2.3.

[0034] (5) Saccharification: Use food-grade lactic acid to adjust the pH to 4.2-4.5, and add 100-150 U / g of glucoamylase;

Abstract

The invention discloses a rice wine making method capable of lowering content of high alcohol, which belongs to the technical field of wine making. From four aspects of assimilable nitrogen source, wheat koji, yeast and post-fermenting temperature and based on a rice wine making technology, the invention provides the rice wine making method capable of lowering content of high alcohol of the rice wine and reducing influences on comfort of consumers. The content of high alcohol in the rice wine prepared by the method is 56.91%-89.47% that of high alcohol in the rice wine prepared by a traditional fermentation technology, so that the damage to wine body harmony caused by excess high alcohol is alleviated, the foreign flavor and the injury to human bodies resulting from the excess high alcohol are reduced, and the drinking comfort of the rice wine is enhanced.

Description

technical field [0001] The invention relates to a rice wine brewing method for reducing the higher alcohol content of rice wine, and belongs to the technical field of wine brewing. Background technique [0002] Higher alcohol refers to the general term for alcohols containing more than 3 carbon atoms, commonly known as fusel oil, which is the main by-product produced in the fermentation process of wine and one of the main aroma and taste substances of wine. Higher alcohols in rice wine mainly include isopropanol, allyl alcohol, n-propanol, isobutanol, n-butanol, tert-butanol, isoamyl alcohol, n-amyl alcohol, benzyl alcohol, β-phenylethanol, etc. An appropriate amount of higher alcohol endows rice wine with a unique mellow, plump, round and harmonious taste, but if the content of higher alcohol is too high, it will produce peculiar smell and damage the human brain and nervous system, causing the drinker to have symptoms of headache and dizziness. Commonly known as "top". Re...
