4-己基间苯二酚对蚕豆籽粒保鲜效果的研究

Study on the effect of 4-hexylresorcinol on broadbean preservation

采用0.01%、0.02%和0.03%三种浓度的4-己基间苯二酚(4HR)溶液和VC溶液浸泡蚕豆10min,观察蚕豆在(1±1)℃贮藏环境下的营养品质和褐变度的变化情况。结果表明:0.02%的4HR处理较好地降低了蚕豆的呼吸强度和乙烯的释放程度,抑制PPO、POD和PAL的活性,减缓MDA和总酚含量的上升,延缓叶绿素降解、VC含量的下降,起到抑制褐变、保持感官品质和良好的营养成分的作用。

The effect of 4-hexylresorcinol（4HR）treatments on browning and enzymatic activities of fresh broad beans were investigated.Broad beans were dipped into solutions of 4HR at 0.01%,0.02% and 0.03% for 10min respectively,then stored at（1±1）℃.Results showed that the treatment with 0.02% 4HR respiratory rate and ethylene production were significantly delayed,the activities of polyphenoloxidase（PPO）,peroxidae（POD）and phenylalanine ammonialyase（PAL）were inhibited.The increasing of malondialdehyde（MDA）levels and the content of totalphenol（TP）were slowly down,while chlorophyll and ascorbic acid were slowly decreased.So 0.02% 4HR could effectively inhibite tissue browning and maintain good sensory and nutrient quality.
