Scientific Background
The main ingredient in the edible vinegar is acetic acid (the content of acetic acid is more than 3.5 %). The edible vinegar also contains a few other organic acids. According to hygienic standard, free mineral acid (sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid and other inorganic acid and oxalic acid) should not be detectable in the vinegar which is made by grains. However, the free mineral acid can be detected in the contaminated vinegar or that made up of inedible acid.
