Abstract: The effects of Cili juice (Rosa roxburghii Tratt) settled by chitosan were analyzed and the changes of main components of Cili juice before and after the fast settlement were determined. The results showed as following: (1) The transparency of settled juice is over 95%, and losses of VC and SOD are respectively below 2%. (2) Removal rates of pectin and tannin causing the secondary precipitation and browning are 100% and 40% respectively. The methed is proved to be better than enzyme reaction and gelatin settlement, through this advanced and practical test.

Key words: Cili (Rosa roxburghii Tratt)juice, soluble chitosan, quality
