Embodiment 1

[0027] A preparation method of apple cider vinegar, comprising the following steps:

[0028] (1) Wash and crush the apples, control the sugar content at 10-12%, and then energize and magnetize to obtain magnetized apple juice;

[0029] (2) Add 0.025% yeast and 1.5% alcohol to the magnetized apple juice, keep the temperature at 33-37°C, and ferment for 3 days to obtain apple wine;

[0030] (3) Add acetic acid bacteria with 0.1% of the mass of apple juice in the apple wine, keep the temperature at 23-27°C, and ferment for 2.5 days to obtain apple cider vinegar;

[0031] (4) Drenching and sterilizing the apple cider vinegar, then adding 0.01% of the mass of apple cider vinegar with methylglyoxal, aging for 12 days, adjusting the acidity to 3.5-4%, and the finished product is obtained.

Embodiment 2

[0033] A preparation method of apple cider vinegar, comprising the following steps:

[0034] (1) Wash and crush the apples, control the sugar content at 10-12%, and then energize and magnetize to obtain magnetized apple juice;

[0035] (2) Add 0.02% yeast and 0.5% alcohol to the magnetized apple juice, keep the temperature at 33-37°C, and ferment for 2.5 days to obtain apple wine;

[0036] (3) Add acetic acid bacteria with 0.1% of the mass of apple juice in the apple wine, keep the temperature at 23-27°C, and ferment for 2 days to obtain apple cider vinegar;

[0037] (4) Drenching and sterilizing the apple cider vinegar, then adding 0.01% of the mass of apple cider vinegar with methylglyoxal, aging for 11 days, adjusting the acidity to 3.5-4%, and the finished product is obtained.

Embodiment 3

[0039] A preparation method of apple cider vinegar, comprising the following steps:

[0040] (1) Wash and crush the apples, control the sugar content at 10-12%, and then put the crushed apple juice in a magnetization machine for magnetization to obtain magnetized apple juice;

[0041] (2) Add 0.015% yeast and 1% alcohol to the magnetized apple juice, keep the temperature at 33-37°C, and ferment for 2 days to obtain apple wine;

[0042] (3) Add acetic acid bacteria with 0.1% of the mass of apple juice in the apple wine, keep the temperature at 23-27°C, and ferment for 3 days to obtain apple cider vinegar;

[0043] (4) Drenching and sterilizing the apple cider vinegar, then adding 0.01% of the mass of apple cider vinegar with methylglyoxal, aging for 10 days, adjusting the acidity to 3.5-4%, and the finished product is obtained.

Abstract

The invention discloses a preparation method of apple vinegar, belongs to the technical field of food processing, and solves the problems of long solid-fermentation period and poor liquid-fermentation quality in the traditional technology. The preparation method comprises the following steps of: (1) cleaning and crushing apples, controlling the sugar degree to be 10-12%, then electrifying and magnetizing, so as to obtain magnetized apple juice; (2) adding yeast with the mass being 0.015-0.025% of the mass of the apple juice and alcohol with the mass being 0.5-1.5% of the mass of the apple juice, and fermenting for 2-3 days at the temperature of 33-37 DEG C, so as to obtain apple wine; (3) adding acetic acid bacteria with the mass being 0.1% of the mass of the apple juice into the apple wine, and fermenting for 2-3 days at the temperature of 23-27 DEG C, so as to obtain the apple vinegar; and (4) carrying out vinegar spraying sterilization on the apple vinegar, then adding methylglyoxal with the mass being 0.01% of the mass of the apple vinegar, ageing for 10-12 days, and adjusting the acidity to be 3.5-4%, so as to obtain finished apple vinegar. The preparation method disclosed by the invention has the advantages that the fermentation period is shortened, the quality of the apple vinegar is improved, the taste of the apple vinegar is soft and mellow, and nutrient substances are rich.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a method for preparing vinegar, in particular to a method for preparing apple cider vinegar. Background technique [0002] Apple cider vinegar is more and more favored by consumers because of its unique flavor and many health functions, and the market prospect is very promising. [0003] At present, most of the apple cider vinegar available on the market is liquid-fermented apple cider vinegar, that is, concentrated apple juice is used as raw material, and liquid fermentation technology is used to separate ethanol fermentation and acetic acid conversion. Generally, it takes 3-7 days to become vinegar, and it can be aged for two months. listed. But the apple cider vinegar of liquid state fermentation is all far inferior to traditional solid-state fermented apple cider vinegar in aspects such as color and luster, fragrance, mouthfeel, health care function. However, the trad...
