2019-03-20 11:56:41

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 they bring many benefits to the food industry. Their main functions are as follows:

Prevent deterioration

For example, preservatives can prevent food spoilage caused by microorganisms, prolong the shelf life of food, and prevent food poisoning caused by microbial contamination. For example, 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, and so on.

Improving Food Sensory Characters

Appropriate use of food additives such as colorants, color preservatives, bleaching agents, food spices, emulsifiers and thickeners can significantly improve the sensory quality of food and meet people's different needs.

Maintaining Nutritional Value

Proper addition of some natural nutritional fortifiers in food processing can greatly improve the nutritional value of food, which is of great significance in preventing malnutrition and nutritional deficiency, promoting nutritional balance and improving people's health level.

Convenient supply

There are more than 20,000 kinds of food on the market for consumers to choose from. Although most of these food products are processed through certain packaging and different processing methods, in production engineering, some products with full color, aroma and taste are mostly added with coloring, flavoring, seasoning and other food additives to varying degrees. It is these numerous foods, especially the supply of convenience food, that bring great convenience to people's life and work.

Convenient Food Processing

The use of defoamers, filter aids, stabilizers and coagulants in food processing can be conducive to food processing operations. For example, when delta lactone gluconate is used as tofu coagulant, it is beneficial to mechanization and automation of tofu production.

Other special needs

Food should meet people's different needs as much as possible. For example, diabetics can't eat sugar, they can use non-nutritious sweeteners or low-calorie sweeteners to make sugar-free food supply.
