Food additives have greatly promoted the development of the food industry and are known as the soul of the modern food industry. This is mainly because it brings many benefits to the food industry. Its main functions are roughly as follows:
- Prevent deterioration
For example: preservatives can prevent food spoilage caused by microorganisms, extend the shelf life of food, and also have the effect of preventing food poisoning caused by microbial contamination. Another example: antioxidants can prevent or postpone the oxidative deterioration of food to provide food stability and storage resistance, while also preventing the formation of potentially harmful fats and oils auto-oxidizing substances. In addition, it can also be used to prevent enzymatic browning and non-enzymatic browning of foods, especially fruits and vegetables. These are of certain significance to the preservation of food.
- Improve the senses
Improve food sensory properties
Appropriate use of food additives such as coloring agents, color retention agents, bleaching agents, edible fragrances, emulsifiers, thickeners, etc. can significantly improve the sensory quality of food and meet people’s different needs.
- Maintain nutrition
Maintain and improve nutritional value
Appropriate addition of certain food nutrition fortifiers that belong to the natural nutrition range during food processing can greatly improve the nutritional value of food, which is of great significance to prevent malnutrition and nutritional deficiencies, promote nutritional balance, and improve people’s health.
- Convenient supply
Increase variety and convenience
There are more than 20,000 kinds of foods on the market for consumers to choose from. Although most of these foods are produced through certain packaging and different processing methods, in the production process, some products with complete colors, aromas and tastes are mostly different. Coloring, flavoring, flavoring and even other food additives are added to a certain extent. It is the supply of these numerous foods, especially convenience foods, that bring great convenience to people’s lives and work.
- Convenient processing
Convenience food processing
The use of defoamers, filter aids, stabilizers and coagulants in food processing can be beneficial to food processing operations. For example, when glucono delta lactone is used as a tofu coagulant, it can be beneficial to the mechanization and automation of tofu production.
Other special needs
Food should meet the different needs of people as much as possible. For example, if people with diabetes cannot eat sugar, they can use non-nutritive sweeteners or low-calorie sweeteners, such as sucralose or aspartame, to make sugar-free food supplies.
There are also companies that formulate their own standards for additives. Leading companies in the industry do not allow the addition of preservatives, sodium cyclamate, colors, and fragrances.
