Study Notes

Chemical Preservatives in Food

Chemical preservatives are substances added to food to prevent spoilage and extend shelf life.
Their primary purpose is to inhibit the growth of microorganisms, such as bacteria, molds, and yeasts.
Some common examples of chemical preservatives include sodium benzoate, potassium sorbate, and sulfur dioxide.

Types of Chemical Preservatives

Antimicrobials: These preservatives prevent bacterial and fungal growth. Examples include nitrates, nitrites, and benzoic acid.
Antioxidants: These preservatives prevent oxidation and rancidity. Examples include BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), and ascorbic acid.
Chelating Agents: These preservatives bind metal ions to prevent spoilage. A common example is EDTA (Ethylenediaminetetraacetic acid).
