What kind of food has food addictives and explain the purpose for each addictive?

Food additives are substances added to food to enhance flavor, appearance, or preservation. For example, preservatives like sodium benzoate prevent spoilage by inhibiting microbial growth, while artificial sweeteners such as Aspartame provide sweetness without calories. Colorants, like Red 40, enhance visual appeal, and emulsifiers, such as lecithin, help mix ingredients that typically don't combine well, like oil and water. Each additive serves a specific purpose to improve the overall quality and shelf life of food products.
