Abstract

The invention discloses a preparation method of a rice wine vinasse extractive, the prepared extractive and an application of the extractive. The preparation method comprises the following steps: (1) secondary fermentation of rice wine vinasse, to be specific, adding water to the rice wine vinasse, and fermenting to obtain feed liquid 1; (2) enzymatic hydrolysis, to be specific, adding protease and glucoside hydrolase to the feed liquid 1 obtained in the step (1), carrying out enzymatic hydrolysis, and filtering to obtain feed liquid 2; (3) purification and concentration, to be specific, decoloring and deodorizing the feed liquid 2 obtained in the step (2), then filtering to obtain feed liquid 3, and concentrating the feed liquid 3, thus obtaining the rice wine vinasse extractive. When the preparation method can also comprise a step (4) or a step (4'), dry powder of the rice wine vinasse extractive or liquid preparation of the rice wine vinasse extractive can be correspondingly prepared. According to the preparation method, the rice wine vinasse is comprehensively and synthetically is utilized, and the economic value of the rice wine vinasse is greatly increased.

Description

technical field [0001] The invention relates to a rice wine distiller's grain extract, a preparation method and application thereof. Background technique [0002] Rice wine contains more than 10 kinds of amino acids, 8 of which are essential amino acids that cannot be synthesized by the human body. It is recorded in "Compendium of Materia Medica" that rice wine can appetize and invigorate the spleen, promote digestion, remove moisture, moisten the skin, activate blood circulation and remove stasis. It is a nutritional product suitable for men, women and children. Modern studies have shown that rice wine has the effects of beautifying and beautifying, energizing and nourishing blood. [0003] Rice wine distiller's grains are by-products of the rice wine brewing process. Rice wine distiller's grains, which use rice as raw material, not only contain unfermented rice, but also a large amount of yeast. Rice contains various peptides of different sizes, which have certain antio...
