Problems solved by technology

Biological acid reduction uses microorganisms to decompose fruit acids, the operation is cumbersome, the conditions are harsh, and it is greatly restricted
Physical acid reduction uses anion exchange resin to adsorb fruit acid, which is not only time-consuming, but also inevitably absorbs the aroma of fruit wine, resulting in a large loss and affecting the flavor of green plum wine
Chemical acid reduction is mainly to add chemical reagents to reduce the tartaric acid content in fruit wine. If the amount used exceeds a certain range, it will affect the taste, color and aroma of fruit wine. The metal ions brought in may also easily cause the instability of the wine body and negatively affect the quality of fruit wine. great influence

Abstract

The invention discloses a method for reducing organic acid of plum wine. The method comprises the following steps that: 1) plums are enucleated and broken, pectinase and cellulase are added, enzymolysis is carried out at 15-18 DEG C for 6 to 10h and filtration is conducted to obtain plum Juice; 2) xylitol by weight of 0.01 to 0.1% of the plum juice are added to the plum juice, the plum juice is cooled to 1 to 2 DEG C at a cooling speed of 5 to 10 DEG C / 30min, the plum juice is stirred during a cooling process with a stirring speed of 1000 to 2000r / min, after cooling, stirring is stopped, insulation and standing are conducted for 1 to 2h, filtration is conducted, and filtrate is taken for spare use; 3) sugar content of the filtrate is adjusted to 16 to 20 degree Bx, yeast is inoculated, and fermentation is conducted to obtain original wine; 4) the original wine is clarified, aging is conducted to obtain the plum wine. The method for reducing the organic acid of the plum wine can effectively reduce tartaric acid and malic acid content in the plum wine, and the prepared plum wine has soft wine body, mellow taste and harmonious aroma.

Description

technical field [0001] The invention belongs to the technical field of brewing, and in particular relates to a method for reducing organic acids in plum wine. Background technique [0002] Green plum, also known as plum fruit and sour plum, grows in subtropical regions with wet summer and dry winter, and is native to China. It has a cultivation history of more than 3,000 years. At present, the green plum cultivation area in my country exceeds 1 million mu, mainly distributed in Guangdong, Guangxi, Fujian, Jiangsu and Zhejiang. The green plum pulp has a mellow aroma, sour and sweet, and has the characteristics of both medicine and food. Green plums are rich in organic acids, mainly including citric acid, malic acid, tannic acid, picric acid, succinic acid, tartaric acid, etc. It is a typical alkaline food and can effectively regulate the acid-base balance in the human body. In addition, green plum also contains resveratrol, terpenoids, sterols and amino acids and other nutr...
