Research progress in extraction technology of pectin from citrus peel and the appli-cation status of pectin
Citrus is the largest fruit crop in planting area and production in the world.The inedible parts of citrus fruit such as peel are produced largely every year.There are many kinds of functional compounds such as pectin,flavonoids,carotenoids,and essential oil in citrus peel.Discarding citrus peel could be a waste of re-sources and pollutant of environment.Extracting pectin from citrus peel is one of the effective ways to recycle citrus waste.In order to develop and utilize citrus peel environment friendly and efficiently,research progress in extraction technology of pectin from citrus peel and the application status of pectin at home and abroad were analyzed.
