Progress on Bioactive Compounds in Citrus Fruit Processing Waste and Their Extraction Technologies

Abstract:

A substantial quantity of waste is generated during the processing of citrus fruits. Such waste is rich in diverse bioactive compounds, including flavonoids, phenols, essential oils, carotenoids, and pectin. The efficient extraction and resource utilization of these compounds hold significant importance in managing the processing pollution and propelling the development of a circular economy. The author presents a comprehensive review of the functional properties and application status of the major bioactive compounds in citrus fruit processing waste. Additionally, it expounds on the principles, advantages, and application outcomes of extraction technologies such as microwave-assisted extraction, supercritical fluid extraction, ultrasound-assisted extraction, and enzymatic hydrolysis methods.
