Question

What are acids? Write the name of two food items which contain acids.

Answer 1

Hint: We know that the given question an acid has been asked which is used in making food. There are various acids that can be used for cooking purposes, such as carboxylic acid. An important carboxylic acid is acetic acid that is produced by fermentation and oxidation of natural carbohydrates.

Complete answer:
The word acid is derived from Latin word 'Acid' which means sour. Hence, we can say that the substances which are sour in taste are called acids. Acetic acid, likewise named as ethanoic acid, and is the utmost important of the carboxylic acids. A dilute that might be approximately five percent by volume of a solution of acetic acid produced through fermentation and oxidation of natural carbohydrates is called vinegar.
Though Vinegar is an aqueous solution of acetic acid and has some trace chemicals that might include flavorings. Acetic acid might be used for cooking, cleaning, baking, and also weed control and may encourage weight loss and cholesterol and lower blood sugar. Vinegar is frequently used in food preparation, chiefly in pickling liquids, other salad dressings and vinaigrettes. The chemical contents of Vinegar have numerous flavonoids, aldehydes and phenolic acids, which vary in content depending on the source material used to make the vinegar. Two food items which contain acid: Orange contains citric acid; Curd contains lactic acid.

Note:
Remember that acetic acid is prepared in industry by air oxidation of chemical acetaldehyde, and by oxidation of ethanol that is ethyl alcohol. Initial research shows that if one can consume two to four tablespoons of vinegar may cause minor reductions in post-meal levels of insulin and blood glucose in people having diabetes.
