Betaine anhydrous surfactants are widely used in the food industry. Adding surfactants to some food preparations can greatly improve production and processing standards, improve product quality, and increase food preservation periods. For example, in the production of ice cream, without surfactants, the quality and structure of the product cannot be controlled, and the moisture content cannot be increased. Another example is about microencapsulation technology,  surfactant has very good emulsion and demulsification properties, so if without surfactant embedding techniques cannot be carried out. Generally speaking, high-quality food production and processing are inseparable from the use of surfactants.

The extensive use of surfactants has greatly promoted the development trend in the field of food additives.

With the continuous improvement of people’s living standards and the continuous improvement of people's requirements for the nutritional content, quality and variety of food, the use of surfactants in the food industry may achieve a higher development trend.
