Answer 2

$\underline \bold{Food \: preservatives}$

Preservatives are used to preserve food for a longer time.

Salt, sodium nitrite, spices, vinegar, and alcohol have been used to preserve foods for centuries. Sodium benzoate, calcium propionate, and potassium sorbate are used to prevent microbial growth that causes spoilage and to slow changes in color, texture, and flavor.
