Embodiment 1

[0034] Such as figure 1 Shown, a kind of method of the present invention utilizes vinegar dregs, vinegar precipitation to brew liquid vinegar, comprises the following steps:

[0035] 1. Raw material processing: the first is the treatment of vinegar residue: after the fermentation of solid-state vinegar, the vinegar in the vinegar residue is drenched with water first, and the residue is dried at 120° C. for 20 seconds by a tunnel-type continuous microwave drier until the moisture is 50% (moisture is too high). Vibrating sieve in the high-impact stage separates chaff and bran), and then sieves bran and chaff through a vibrating sieve, and the bran is pulverized by an ultrafine pulverizer to a fineness of 300 mesh (the purpose of pulverization is to make the bran particles smaller and the fiber Tissue is destroyed, easy to liquefy), and then go to pulp and liquefy, and the chaff returns to ferment again; the second is aging solid vinegar precipitation treatment: after aging solid...

Embodiment 2

[0042] Such as figure 1 Shown, a kind of method of the present invention utilizes vinegar dregs, vinegar precipitation to brew liquid vinegar, comprises the following steps:

[0043] 1. Raw material processing: the first is the treatment of vinegar residue: after the fermentation of solid-state vinegar, the vinegar in the vinegar residue is drenched with water first, and the residue is dried at 120° C. for 20 seconds by a tunnel-type continuous microwave drier until the moisture is 50% (moisture is too high). Vibrating sieve in the high-impact stage separates the chaff and bran), and then sieves the bran and chaff through a vibrating sieve, and the bran is pulverized by an ultrafine pulverizer to a fineness of 400 mesh (the purpose of pulverization is to make the bran particles smaller and the fiber Tissue is destroyed, easy to liquefy), and then go to pulp and liquefy, and the chaff returns to ferment again; the second is aging solid vinegar precipitation treatment: after agi...

Embodiment 3

[0050] Such as figure 1 Shown, a kind of method of the present invention utilizes vinegar dregs, vinegar precipitation to brew liquid vinegar, comprises the following steps:

[0051] 1. Raw material processing: the first is the treatment of vinegar residue: after the fermentation of solid-state vinegar, the vinegar in the vinegar residue is drenched with water first, and the residue is dried at 120° C. for 20 seconds by a tunnel-type continuous microwave drier until the moisture is 50% (moisture is too high). The high-impact post-stage vibrating sieve separates the chaff and bran), and then sieves the bran and chaff through a vibrating sieve. Tissue is destroyed, easy to liquefy), and then go to pulp and liquefy, and the chaff returns to ferment again; the second is aging solid vinegar precipitation treatment: after aging solid vinegar, first extract the upper 98% of the clear liquid, and the remaining 2% of the sediment (PH3.0, total acid 6.0g / 100ml) for subsequent use; the ...

Abstract

The invention discloses a method for utilizing vinegar residues and vinegar precipitates to brew liquid vinegar. The method comprises the following steps of (1) pretreatment of rice, the vinegar residues and the vinegar precipitates; (2) liquefying, wherein the pretreated rice, the pretreated vinegar residues, the pretreated vinegar precipitates and water are blended with one another for size mixing, amylase is added for instant liquefaction at the high temperature, and then cooling is conducted for desaccharification to obtain a liquefied solution; (3) liquid vinegar fermentation, wherein thevinegar precipitates are added to adjust the pH value of the liquefied solution to be 4.0-4.5, saccharifying enzymes and cellulase are added for saccharification to obtain a saccharified liquid, andalcoholization and acetification are performed on the saccharified liquid to obtain liquid raw vinegar. Compared with the liquid vinegar fermented in the prior art, the liquid vinegar fermented through the method has more abundant nutrients, a unique flavor and a yellow and bright color, recycling of the vinegar residues and coarse precipitates is achieved at the same time, and therefore the method is more environmentally friendly and healthy.

Description

technical field [0001] The invention relates to the technical field of vinegar preparation technology, in particular to a method for brewing liquid vinegar by using vinegar residue and vinegar precipitation. Background technique [0002] Liquid vinegar is a traditional Chinese condiment. It uses rice or alcohol as the main raw material and is fermented by microorganisms to form a liquid condiment with special color, taste and shape. [0003] According to the GB / T18187-2000 standard, my country's brewed vinegar is divided into two categories according to different production processes: one is solid-state fermented vinegar, and the other is liquid-state fermented vinegar. The first type is produced by the traditional fermentation process in my country, and the general fermentation period is 30-40 days. The second category is a quick brewing production process (the fermentation period is generally 20-26 hours, and the acid production is 7-8g / 100ml), which is based on the intro...
