The main function of food preservatives

Food additives have greatly promoted the development of the food industry and are known as the soul of modern food industry, mainly because they bring many benefits to the food industry.
The main functions of food additives are roughly as follows:
Prevent Deterioration
For example, preservatives can prevent food spoilage caused by microorganisms, extend the shelf life of food, and also prevent food poisoning caused by microbial contamination.
For example, antioxidants can prevent or delay the oxidation and spoilage of food, providing stability and shelf life, while also preventing the formation of potentially harmful lipid auto oxidizing substances.
In addition, it can also be used to prevent enzymatic and non enzymatic browning of food, especially fruits and vegetables. These have certain significance for the preservation of food.
Improve Sensory Experience
Improving the sensory characteristics of food - the appropriate use of colorants, color protectants, bleaching agents, flavorings, emulsifiers, thickeners and other food additives can significantly enhance the sensory quality of food and meet people's different needs.

Maintain Nutrition
Maintaining and improving nutritional value - Properly adding certain natural nutritional fortifiers during food processing can greatly enhance the nutritional value of food, which is of great significance in preventing malnutrition and nutrient deficiency, promoting nutritional balance, and improving people's health.
Convenient Supply
Increasing variety and convenience - There are already over 20000 types of food available for consumers to choose from in the market. Although most of these foods are produced through certain packaging and different processing methods, in the production process, some products that are color, aroma, and taste perfect are mostly added with coloring, aroma enhancement, seasoning, and other food additives to varying degrees. It is precisely these numerous foods, especially the supply of convenience foods, that bring great convenience to people's lives and work.
Convenient Processing
Convenient food processing - the use of defoamers, filter aids, stabilizers, and coagulants in food processing can facilitate food processing operations. For example, when using gluconic acid delta lactone as a tofu coagulant, it can facilitate the mechanization and automation of tofu production.
Other Functions
Special needs - Food should meet people's different needs as much as possible. For example, if diabetics cannot eat sugar, they can use non nutritional sweeteners or low calorie sweeteners, such as sucralose or aspartate phenylalanine methyl ester, to make sugar free food supplies.
Some companies also establish their own standards for additives, and among the leading companies in the industry, some have set standards for preservatives, saccharin, pigments, and fragrances that are not allowed to be added.
