Research progress on functional components of pomelo peel

Pomelo peel is a by-product of pomelo processing. It not only has edible function, but also has certain practical value, which has been a research hotspot. In this paper, the research progress of functional components of grapefruit peel in recent years was reviewed, including the nutritional components of grapefruit peel, the efficacy of functional active substances and the extraction methods of functional active substances. Functional active substances such as limonin, flavonoids, dietary fiber and natural pigments of grapefruit peel have multiple effects including anti-cancer, antibacterial, anti-aging, improvement of intestinal flora, hypoglycemia, and hypoglycemia, and have high research value. The extraction of functional active substances from grapefruit peel involves reflux method, Soxhlet extraction method, ultrasonic extraction method, microwave-assisted extraction method, macroporous resin adsorption method, alkali leaching method, enzyme extraction method and other methods. The application prospect of pomelo peel in food, industry, medicine and health care was prospected, providing reference for the comprehensive utilization of pomelo peel resources.
