Production process for brewing apricot fruit vinegar from apricot peel pomace

Abstract

The invention discloses production technology for brewing apricot fruit vinegar by utilization of apricot bark residue, which comprises: firstly, collecting the apricot bark residue into a stainless steel jar, adding water for stirring, adjusting the content of soluble solid to be between 7 and 9 DEG BX, adjusting the product temperature to be between 42 and 45 DEG C, and transferring an apricot skin residue mixture into an alcohol fermenter; secondly, simultaneously adding active dry yeast and mashed fruit cellulose complex enzyme, controlling the fermentation temperature to be between 28 and 32 DEG C and the fermentation time to be between 48 and 52 hours, and making alcohol fermentation finished when the sugar degree of juice is reduced to be less than or equal to 0.5 percent and the alcohol content of the juice reaches 5 to 7 percent; thirdly, transferring mash obtained in the prior step into an acetic acid fermenter, adding acetic acid bacteria for acetic fermentation, and controlling the fermentation temperature to be between 32 and 38 DEG C; and fourthly, obtaining finished products after the steps of brewing, aging, mixing, filtration, sterilization, filling and sealing in turn.

Description

technical field [0001] The invention relates to a production process of fruit vinegar, in particular to a production process for brewing apricot fruit vinegar with apricot peel residue. Background technique [0002] my country's Xinjiang is rich in apricots, and the production of concentrated apricot jam needs to purchase a large amount of fresh apricots as raw materials every year. According to statistical calculations, about 110 kg of apricot skin dregs will be discharged after 1 ton of apricots are used to produce concentrated apricot jam. Usually, an enterprise producing concentrated apricot jam discharges thousands of tons of skin dregs annually. In the past, these apricot skin dregs have not been deeply developed and utilized, and can only be used as roughage or discarded as waste, with extremely low utilization value and even pollute the environment. After detection and analysis, the apricot skin dregs mainly contain pulp fiber and a very small part of pulp pulp, its...

AI Technical Summary

Problems solved by technology

Although this method can brew apricot fruit vinegar, but the whole fruit of apricot is directly used as raw material for processing. First, the consumption of apricot is relatively large. Second, the brewing time is long, the arrangement of the production process is relatively rough, and the production cost is high.
