Blending edible vinegar and preparation method thereof

Abstract

The invention discloses blending edible vinegar, which is prepared by the following steps of: mixing 60 to 70 weight percent of white vinegar, 5 to 15 weight percent of summer vinegar, 10 to 15 weight percent of five-year aged vinegar and 15 to 25 weight percent of fully smoked vinegar; and decocting the vinegar at high temperature of between 80 and 90DEG C. The prepared blending edible vinegar has mild and sweet mouthfeel, rich aromatic components, high functional hygiene factor content, a ratio of total acid to reducing sugar of about 7:3, a ratio of volatile acid to nonvolatile acid of about 6:4, the ligustrazine concentration of more than or equal to 50mg / L and the general flavones concentration of more than or equal to 70mg / 100mL. Substances influencing flavor and functional factors in the edible vinegar are systematically and quantitatively coordinated, problems of unstable quality, difference in different batches and the like in the conventional edible vinegar brewing are improved, and the edible vinegar with typical flavor and functions, which ensures that sensorial taste and instrument analysis results meet the expected design requirement, is prepared, so that high quality edible vinegar is produced.

Description

technical field [0001] The invention relates to a kind of vinegar, in particular to a blended vinegar prepared by blending semi-finished vinegar prepared by various processes as a raw material, and a preparation method of the blended vinegar.
