Abstract

The invention discloses a method for increasing the content of beta-phenethyl alcohol in yellow rice wine. After being stir-fried, wheat is crushed into cloves for use; treated rice and stir-fried wheat are uniformly mixed, then aspergillus albicans is inoculated, the mixture is put into an aspergillus box for aspergillus treading, the temperature of a culture chamber is controlled to be 15-20 DEGC for 60-90 days of low-temperature culture, and then after-ripening is conducted for 60-90 days; the treated wheat and stir-fried wheat are uniformly mixed, then aspergillus niger is inoculated, themixture is put into an aspergillus box for aspergillus treading, the temperature of the culture chamber is controlled to be 65-70 DEG C for 60-90 days of high-temperature culture, and after-ripeningis conducted for 30-60 days; treated glutinous rice and stir-fried wheat are uniformly mixed, then monascus purpureus is inoculated, the mixture is put into an aspergillus box for aspergillus treading, the temperature of the culture chamber is controlled to be 30-35 DEG C for 30-60 days of middle-temperature culture, and after-ripening is conducted for 60-90 days. Three kinds of aspergillus are mixed for use, the respective advantages are taken, the vigor of saccharifying enzyme, the vigor of liquifying enzyme, the vigor of acid proteinase, the content of the beta-phenethyl alcohol, the content of 4-ethyl guaiacol and the content of haematochrome of the yellow rice wine are greatly increased, and the content of the beta-phenethyl alcohol is effectively increased.

Description

technical field [0001] The invention relates to the field of production and fermentation of rice wine cooking wine, in particular to a method for increasing the content of beta-phenylethanol in rice wine. Background technique [0002] Rice wine cooking wine, its main component is rice wine, also known as rice wine cooking wine, rice wine is a national specialty of China, with unique flavor and self-contained style. Yellow rice wine aroma is an important flavor substance of rice wine, which plays an important role in distinguishing the style, quality and quality of rice wine. There are about 70 kinds of substances that constitute the aroma components of rice wine, mainly five types of substances such as alcohols, acids, esters, aldehydes, and ketones, and the most abundant substances are alcohols. Among the alcohols that make up the aroma, the most abundant is β-phenylethyl alcohol, which has an elegant aroma of honey and rose, and a sweet and refreshing taste in the mouth. ...
