Edited by Huma Saeed || By Sawaira Riaz || Published on February 1, 2024
Class I preservatives are naturally occurring substances, often used in their natural form, while Class II preservatives are synthetic and chemically manufactured to preserve food.

Key Differences

Class I preservatives include naturally sourced substances like salt, sugar, and vinegar, used in their unaltered form to prolong the shelf life of food products. In contrast, Class II preservatives are synthesized chemicals like benzoates, sulfites, and nitrates, specifically created to prevent spoilage and extend food freshness.
