Abstract

This invention discloses a kit that can distinguish brewed vinegar and blended vinegar. It includes box, there are standard color plate, color comparison tube, trickle irrigator, reagent bottle A, B and C. Reagent in A is acidic potassium permanganate aqueous solution of mass percent concentration 1-3%. PH value of the acidic permanganate aqueous solution is 1.5-4.0. Reagent in B is sodium bisulphate aqueous solution of concentration is 5-10%. Reagent in C is chromotropic acid sulfuric acid aqueous solution of concentration is 2-5%, the concentration of sulfuric acid aqueous solution is 0.02-0.05 mol / L. all kinds of vinegars in commodities circulation fields and vinegar generating enterprise can be quickly and accurately detected by this method. Its operation is simple, cost is low, and unprofessional man can also use it to make spot detecting.

Description

technical field [0001] The invention belongs to the technical field of food detection, and relates to a kit for identifying brewed vinegar and preparing vinegar. Background technique [0002] Vinegar is one of the essential condiments in people's daily life. Brewed vinegar refers to a liquid sour condiment brewed by microbial fermentation using various materials containing starch and sugar alone or in combination. It contains alcohol, aldehyde, ester, reducing sugar, free amino acid and other nutritional components, including liquid fermented vinegar and solid fermented vinegar. Prepared vinegar refers to brewed vinegar as the main body (accounting for about 50% of the volume), mixed with edible glacial acetic acid, food additives and other seasoning vinegar, which does not have health care effects. However, a considerable part of the prepared vinegar in the market is illegally blended with glacial acetic acid (or even industrial glacial acetic acid) to sell at a low price...
