摘  要:
以大久保桃(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(AsA),0.01%4-HR+1%CA+1%AsA处理均不同程度地抑制了Hunter L值(表示色泽深浅)的下降和Hunter a、b值(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处理效果不明显。

摘  要:
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 (AsA) and 0.01% 4-HR+1%CA+1%AsA 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.
