Complete answer:Vinegar is a key preservative used in pickling and various culinary activities. Vinegar means sour wine because it is an aqueous solution of fermented acetic acid produced from ethanol fermentation. Vinegar was made from dates, beer, and figs in ancient times. Vinegar is produced either by slow fermentation or fast fermentation processes industrially. Longer fermentation periods are preferred as it allows for the collection of nontoxic slime of acetic acid bacteria. Fast production processes produce vinegar in one to three days. The composition of vinegar includes acetic acid, some trace chemicals, and flavoring substances. Acetic acid is present in 5-8 percent by volume. Different fruits or fruit extracts are used as flavoring substances in vinegar.
