Detailed explanation-1: -Preservatives are the substances which are used for food preservation. They are of two types, natural and chemical. Natural preservatives include oil, sugar, salt, etc., whereas chemical preservatives include vinegar, sodium acetate etc.

Detailed explanation-2: -Vinegar may be used to pickle food, a preservation method that extends the shelf life of perishable foods by killing bacteria. Pickling involves soaking a food in a brine solution made from vinegar, water, salt, and sugar, which also changes the food’s flavor. There are several types of vinegars available.

Detailed explanation-3: -The acid from the vinegar, along with naturally forming acids in the food itself, slows down that decaying process. “There are certain salts, ‘’ Xavier adds, “especially those containing calcium, that will help preserve some of the crunchiness of the pickle.” You’ll find those salts in commercial pickles.
