What is the main purpose of food additives?

The primary purpose of food additives is to improve sensory attributes or extend shelf life. Food additives can enhance the taste, texture, appearance, and aroma of products, making them more appealing to consumers. For example, preservatives are a category of additives specifically designed to prolong the shelf life of foods by preventing spoilage due to microbial growth, oxidation, or chemical reactions.

Additives can also include substances that improve the processing of food, such as emulsifiers and stabilizers, which help maintain consistent texture and prevent separation in products like salad dressings or ice creams. The use of food additives is essential in ensuring that products remain safe and appealing over time, which ultimately benefits consumers and manufacturers alike.
