E235 is the European food additive code for natamycin. Natamycin is a naturally occurring antifungal agent produced by the bacterium Streptomycesnatalensis. It is commonly used as a food preservative to inhibit the growth of molds and yeast in various food products.

Antifungal Properties:

• Natamycin is effective against a wide range of molds and yeast, making it valuable in preventing spoilage in certain food items. It acts by inhibiting the growth of fungal spores and preventing their reproduction.

Usage in the Food Industry:

• Natamycin is approved for use in the food industry as a preservative for various food products, including cheese, cured meats, dried fruits, and certain baked goods. It helps extend the shelf life of these products by preventing the development of visible mold.

Cheese Coating:

• One of the common applications of natamycin is as a coating for the surface of certain cheeses. It forms a protective barrier that inhibits mold growth, particularly on the rind, without affecting the quality of the cheese inside.

Safety Considerations:

• Natamycin is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. It has been evaluated by food safety authorities, including the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA).

Minimal Impact on Flavor and Texture:

• When used at recommended levels, natamycin is known to have minimal impact on the taste, texture, and overall quality of food products. It is considered a selective inhibitor, targeting fungi while having little effect on bacteria or yeast used in food fermentation processes.

Natural Origin:

• Natamycin is naturally produced by the bacterium Streptomycesnatalensis through a fermentation process. Its natural origin is often emphasized as a positive aspect in the context of food safety and clean label preferences.

Packaging Material Treatment:

• Natamycin can also be used to treat the surface of packaging materials that come into contact with food, providing an additional layer of protection against mold contamination during storage and transport.

International Approvals:

• Natamycin is approved for use in many countries around the world, and it is included in the Codex Alimentarius list of food additives.
