Ultrasonic-assisted red pomelo polyphenol extraction method and application

The invention provides an ultrasonic-assisted red pomelo polyphenol extraction method and application. The polyphenol component in the red pomelo is extracted through the following steps: firstly, performing activation pretreatment on red pomelo dry powder by adopting a low-temperature plasma device, and destroying a cell wall structure so as to improve the accessibility of combined polyphenol; then cellulase, pectinase, hemicellulase and beta-glucosidase are added into a biodegradable deep eutectic solvent to synergistically hydrolyze the cell wall polysaccharide, and combined polyphenol is released; then applying pulse type ultrasonic wave to assist extraction under a low-temperature condition, so that polyphenol is fully dissolved out and enters the eutectic solvent; and finally, carrying out solid-liquid separation to obtain the red pomelo polyphenol extract. Compared with a conventional heat extraction method, the method has the advantages that the extraction rate of the polyphenol of the red pomelo is remarkably increased at a lower temperature, the degradation of the polyphenol is effectively avoided, and the content of the total polyphenol and the antioxidant activity are increased; the method is green and environment-friendly, and can be applied to the health industry as an antioxidant.
