Preservatives in Canned Foods .

Preservatives are chemicals added to food to prevent spoilage, extend shelf life, and maintain taste and texture.

Common preservatives include sodium benzoate, potassium sorbate, and citric acid, each serving specific functions like controlling mold or acidity.

They help preserve the freshness of food, prevent bacterial growth, and make food safe for longer storage.

Natural preservatives come from plant-based sources, while synthetic ones are chemically manufactured, each with different effects on health.

Some preservatives may cause allergic reactions or other health issues, though many are deemed safe in low amounts by food safety authorities.

They reduce food waste, provide convenience, and allow for seasonal foods to be enjoyed year-round.

Techniques like freezing, vacuum sealing, and using high-pressure processing (HPP) are natural ways to extend shelf life.

Check labels for preservatives, opt for organic canned foods, or make fresh meals at home to avoid unnecessary additives.
