What is the Difference Between Food Additives and Preservatives?

The main difference between food additives and preservatives is that preservatives are a subset of food additives, with the primary purpose of extending the shelf life of certain food products. Food additives, on the other hand, are substances added to food to improve it in various ways, such as enhancing flavor, color, texture, or appearance. Some food additives have roles other than preservation, such as flavoring and artificial coloring.

Some common types of food additives include:

• Anti-caking agents: prevent ingredients from becoming lumpy
• Antioxidants: prevent foods from oxidizing or going rancid
• Artificial sweeteners: increase the sweetness
• Emulsifiers: stop fats from clotting together
• Food acids: maintain the right acid level
• Colours: enhance or add color
• Humectants: keep foods moist
• Flavours: add flavor

Preservatives are a type of food additive added to food to prolong shelf life and protect products from being broken down by microorganisms, such as mold, bacteria, and yeast. Some examples of traditional preservatives include salt, sugar, vinegar, and natural spices.
