摘要
为研究低温对蚕豆鲜荚贮藏品质的影响,通过对其结冰点的研究,设置不同的冷藏温度0、4、8℃,定期测定贮藏期间的 PPO 活性、褐变指数、质量损失率等指标。结果表明:蚕豆鲜荚的结冰点为-0.8℃;0℃处理组的 PPO 活性、褐变指数、质量损失率、籽粒色泽变化均小于其余处理组,0℃处理组的叶绿素含量较高;而0℃处理组的硬度指标相对较好。各低温处理组对蚕豆籽粒中的VC含量影响的差异均不显著(p>0.05),蚕豆鲜荚适宜在0℃条件下贮藏。
In order to study effect of low-temperature on quality of broad bean fresh pod, set different low-temperature storage （0,4,8℃ ）by studying freezing point and measured its activity of PPO, decay index and mass loss rate during storage at regular intervals.The results indicated that freezing points of broad bean pod were -0.8 ℃ ;the effects of the treatment of 0 ℃ on PPO activity, decay index, mass loss rate and color＇ s change was less than the rest of treatments, the effects of the treatment of 0 ℃ on chlorophyll content was higher than the rest of treatments.The indexes of hardness of broad bean pod by the treatment of 0℃ were better than others.Effects of different low-temperaiure treatments on Vc had no significant （p 〉 0.05 ）.The broad bean fresh pod were suitable for storage at 0 ℃.
