Ultrasound-assisted extraction and modification of dietary fiber

Abstract

Dietary fiber has good nutritional value and physiological function. Therefore, how to prepare high-quality dietary fiber has become a hot issue in the field of dietary fiber research. Herein, the research status of extraction and modification of dietary fiber by ultrasonic technology in recent years was summarized. The characteristics and working principle of ultrasonic were analyzed. The effect of ultrasonic extraction and modification was analyzed, and the working mechanism and influencing factors of ultrasonic extraction and modification were expounded. Finally, the existing problems were summarized and the development prospect of ultrasonic technology was prospected, in order to provide theoretical reference for high-value utilization of dietary fiber resources. It indicates that the ultrasonic technology has the advantages of high extraction efficiency, mild extraction conditions, excellent modification effect, environmental friendliness and low energy consumption, which makes it one of the most promising technologies in the extraction and modification of dietary fiber.
