Abstract: The changes in Hunter L, a, b or browning index and activities of polyphenoloxidase (PPO) and peroxidase (POD), total phenol content in fresh-cut peach(Prunus persica L.) treated by 4-hexylresorcinol (4-HR) were measured during storage at 0℃and 5℃. The results showed that treatments with 0.01% 4-HR, 0.01% 4-HR+1% citric acid (CA), 0.01% 4-HR+1% ascorbic acid (AA) and 0.01% 4-HR+1%CA+1%AA reduced the decline of Hunter L and the increase of Hunter a or b, to a various extent, delayed the time in flesh browning, inhibited activities of PPO and POD, and maintained total phenol contents. However, inhibitory effect of the browning by 4-HR was not significant.

Key words: Peach, 4-Hexylresorcinol (4-HR), Browning, Storage
