Problems solved by technology

However, the existing apple cider vinegar production process either adopts a pure liquid fermentation process or a pure solid state fermentation process, wherein the pure liquid state fermentation process has a short fermentation time and a low content of volatile components in the product, resulting in a lack of product flavor and a slightly sour taste; The fermentation process is cumbersome, the fermentation time is too long, and the production cost is high

Abstract

The invention provides a technology of producing apple vinegar by a thin-solid method. The technology comprises the following technical steps: (1) juicing, (2) high-temperature sterilization of fruitjuice, (3) alcohol fermentation: adding saccharomycete, yeast and moldy bran into the fruit juice for fermentation, (4) acetic fermentation: adding bran, rice hulls and acetic bacteria into an alcoholized material obtained in the previous step, (5) pressure filtration and aging, and (6) allocation and sterilization. Compared with the traditional pure liquid fermentation technology, the technologyadopts the liquid alcohol fermentation in an earlier stage, and the acetic solid fermentation in a later stage after the fruit juice is alcoholized completely; an acetic fermentation period is prolonged; a fermentation progress is relatively slow, so that an apple vinegar product contains more ester volatile substances; a flavor of the product is improved; and the product has a better color.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a process for producing apple cider vinegar by diluting before solidifying. Background technique [0002] Apple is one of the four major fruits in the world. It is rich in multivitamins, sugar, pectin, malic acid, citric acid, tannic acid, and fine fiber, etc., and has high nutritional value. At present, a variety of apple cider vinegar made from apples has been developed on the market, which are deeply loved by consumers. However, the existing apple cider vinegar production process either adopts a pure liquid fermentation process or a pure solid state fermentation process, wherein the pure liquid state fermentation process has a short fermentation time and a low content of volatile components in the product, resulting in a lack of product flavor and a slightly sour taste; The fermentation process is complicated, the fermentation time is too long, and the production cost i...
