摘要: 以久保桃(Prunus persica L.)为试材,研究了 4-己基间苯二酚(4-HR)处理鲜切桃后在 0℃和5℃下贮藏期间的色泽变化及其生理基础。结果表明:0.01% 4-HR、0.01% 4-HR + 1% 柠檬酸(CA),0.01% 4-HR + 1% 抗坏血酸(AA),0.01% 4-HR + 1% CA + 1% AA 均不同程度地抑制了 Hunter L 值的下降和Hunter a 、b 值(Hunter L 表示色泽深浅,Hunter a、b表示彩度)的上升,延缓了褐变,抑制了多酚氧化酶(PPO)、过氧化物酶(POD)的活性,保持了总酚含量。另外,单一 0.01% 4-HR处理效果并不明显。

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
