Food processing is the set of methods and techniques used to transform raw ingredients into food for consumption by humans. The food processing industry utilizes these processes. Food processing often takes clean, harvested components and uses these to produce attractive and marketable food products.

Benefits of food processing includes toxin removal, preservation, improving flavor, easing marketing and distribution tasks, and increasing food consistency. In addition, it increases seasonal availability of many foods, enables transportation of delicate perishable foods across long distances, and makes many kinds of foodstuffs safe to eat by removing the microorganisms. Food processing can also add extra nutrients through fortification.

Negative impacts: Food processing frequently lowers nutritional value, and sometimes toxic chemicals are added or created in the food during processing such as aromatic hydrocarbons. Some techniques alter food flavor negatively. In addition, high quality and hygiene standards must be maintained to ensure consumer safety and not all food processors comply with these standards.
