What it is
Salt crystals are a common name for sodium chloride, a mineral compound. It is naturally found in seawater and in underground deposits as rock salt. It is typically harvested through evaporation of seawater or mining, then purified and crystallized.
Why it's used
Salt is widely used in food manufacturing as a flavor enhancer and a preservative. It adds taste to foods and helps extend shelf life by drawing out moisture, which inhibits microbial growth. It is found in almost all processed foods, including snacks, baked goods, cured meats, and canned vegetables.
Health notes
Salt (sodium chloride) is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). It is an essential nutrient needed for proper body function. However, consuming too much sodium can contribute to high blood pressure in some individuals. The FDA Daily Value for sodium is 2,300 mg. JECFA has evaluated sodium chloride, but did not set a numeric acceptable daily intake, as it is an essential nutrient.
