1. Preventing deterioration

Preservatives are food additives, which can prevent food spoilage caused by microorganisms, prolong the shelf life of food, and prevent food poisoning caused by microbial contamination. Antioxidants can prevent or delay the oxidation of food to provide food stability and storage resistance, but also to prevent the formation of potentially harmful lipid autoxides. In addition, it can also be used to prevent enzymatic and non-enzymatic browning of foods, especially fruits and vegetables. These are significant for food preservation.

2. Improving the Sensory Characters of Food

Food color, aroma, taste, shape and texture are important indicators of food quality. Appropriate use of food additives such as colorants, color preservatives, bleaching agents, edible spices, emulsifiers and thickeners can significantly improve the sensory quality of food and meet people's different needs.

3. Maintaining or Improving the Nutritional Value of Food

Proper addition of some food nutrient fortifiers which belong to the natural nutritional range in food processing can greatly improve the nutritional value of food, which is of great significance to prevent malnutrition and nutritional deficiency, promote nutritional balance and improve people's health level.

4. Meeting Other Special Needs

Food should meet people's different needs as much as possible. For example, people with diabetes can't eat sugar, they can use non-nutritious sweeteners or low-calorie sweeteners, such as sucralose or aspartate phenylalanine methyl ester, to make sugar-free food supply.
