Which of the following statements is true about food additives?

Food additives play a crucial role in food production and processing, and one of their primary functions is to enhance both preservation and flavor. Certain additives, such as preservatives, help extend the shelf life of food products by preventing spoilage and microbial growth. Flavor enhancers, on the other hand, improve or restore the taste of foods, making them more appealing to consumers. This multifaceted use is essential for maintaining food quality and safety in an industry where product appeal and longevity are vital.

The other statements presented do not accurately reflect the reality of food additives. While some additives can be harmful, not all are dangerous; many are deemed safe for consumption and undergo extensive testing. The notion that only natural additives are permitted is also misleading, as both natural and synthetic additives are regulated for safety and efficacy. Lastly, food additives are subject to strict regulatory oversight by organizations such as the Food and Drug Administration (FDA) or similar bodies in other countries, ensuring that they meet safety standards before being approved for use in food products.
