Problems solved by technology

[0003] Vinegar has been a traditional Chinese condiment since ancient times, but at present, domestic vinegar is mainly brewed from grain and fruit, and there is no precedent for brewing sap vinegar with birch sap as the main raw material. Birch sap is edible The research and development of vinegar is still in a blank state

example 1

[0022] A kind of white birch sap vinegar of example 1, take white birch sap and white sugar as raw material, preparation method comprises the following steps:

[0023] a. Every year, when the birch tree turns green and grouts in spring, it starts to collect sap. Before collecting the sap, drill holes to investigate. If there is sap seepage, collect the sap immediately. Transport the collected birch sap to the processing site as soon as possible, filter it and put it into the fermentation tank Add white sugar to make the sugar content of 1L fermented liquid 120g, activate dry fruit wine yeast in 2% sugar water or fermented liquid at 36°C, add 0.2g dry yeast to 1L fermented liquid to calculate the usage amount, place at temperature after inoculation Fermentation is carried out in an environment of 20-30°C. When the residual sugar drops below 4g / L, the alcoholic fermentation ends and the alcohol content is 7º;

Abstract

The invention discloses white birch liquid vinegar and a preparation method thereof. According to the preparation method, white birch liquid and white sugar are used as raw materials, white birch liquid raw vinegar is obtained by carrying out alcoholic fermentation and acetic fermentation, clarifying, filtering, sealing and aging for one month or more, and the white birch liquid vinegar with totalacid content of greater than 3% is obtained by blending the white birch liquid raw vinegar with different acidities according to different ratios. The white birch liquid vinegar is clear in physicalappearance and uniform in color, is light yellow, glossy, sour in taste and soft, lasting in aftertaste and mellow in mouth feel, and has aroma of vinegar and faint scent of birch juice.

Description

technical field [0001] The invention relates to the technical field of edible vinegar brewing, in particular to birch sap edible vinegar and its brewing technology. Background technique [0002] Birch sap is a colorless or slightly yellowish transparent liquid that flows out of birch trees in spring, because it contains a variety of nutrients needed by the human body, such as reducing sugars, multivitamins, 11 There are 17 kinds of fatty acids, 17 kinds of amino acids, 17 kinds of inorganic salts, and 15 kinds of trace elements. They have unique medicinal and edible values, so they are called "magic tree water". There are a large number of birch resources in my country, but the utilization rate of birch sap resources is low. The development of birch sap edible vinegar provides a new way for the development and utilization of birch forest resources. [0003] Vinegar has been a traditional Chinese condiment since ancient times, but at present, domestic vinegar is mainly brewe...
