Detailed explanation-1: -Salt is used in raw mangoes, amla, and tamarind to preserve them by draining out water from them through osmosis that will inhibit the growth of bacteria and further enhance the preservation of these items.
Detailed explanation-2: -Traditionally mango pieces are stored by dry salting process. This method involves storing mango pieces over layers of salt. Changes in colour, texture and microbiological spoilage are the common problems associated with this method.
Detailed explanation-3: -ii) Applying salt on the raw mangoes cut the bitterness of the mango, which makes the mango tasty for eating.
Detailed explanation-4: -Salt is effective as a preservative because it reduces the water activity of foods. The water activity of a food is the amount of unbound water available for microbial growth and chemical reactions.
