Abstract:
The by-products of Lingnan characteristic fruits are rich in active substances such as dietary fibers, pectins, polyphenols, functional oils, pigments and essential oils. Extraction and utilization of these active ingredients can turn waste into treasure, and increase the utilization rate and added value of raw materials. This paper reviewed the extraction technologies for the active components in the by-products of Lingnan characteristic fruits, including microwave extraction, ultrasonic extraction, enzymatic extraction, pulsed electric field extraction, high-voltage electrostatic field extraction, radio frequency extraction, supercritical extraction and multi-technology synergistic extraction. Moreover, this paper also discussed the applications of these active ingredients as functional ingredients in the fields of healthcare food, antimicrobial preservation, biological materials and cosmetics, in order to provide reference for the discovery and utilization of functional components in fruit by-products.
