| 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. |
