Dear Student,

◆ Salt is used as preservative in food because -

• Common salt has chemical formula NaCl.
• It has high absorptive power. It absorbs water from food.
• As food gets dehydrated, microbes don't get enough water and growth is inhibited.
• Also high concentration of salt exerts direct toxic effect causing death of microbes.
• Hence, salt is used as food preservative.
