摘  要：
以黄秋葵为实验材料,对黄秋葵进行真空预冷、冰水预冷及冷库预冷处理,研究不同预冷方式对黄秋葵降温速率及保鲜效果的影响。结果表明,真空预冷方式30min内即将黄秋葵原料从25℃降至6℃,极显著地优于冰水预冷与冷库预冷(p<0.01)。结合保鲜效果表明,相比其他预冷方式,真空预冷能明显降低黄秋葵失重率及推迟呼吸高峰出现,延缓可溶性糖含量下降。贮藏12d时真空预冷实验组黄秋葵原料仍能保持其VC原有含量的50%以上,商品率达到95%。结果表明黄秋葵的适宜预冷方式为真空预冷。

摘  要：
The experiment selected okra as experimental material.In order to investigate the effect of different precooling on the hypothermal rate and freshness of retaining of okra,the okra was treated by vacuum cooling,ice water pre-cooling and cold storage pre-cooling.The results showed that: the group of vacuum cooling way could reduce the temperature from 25℃ to 6℃ in 30min,and it was significantly better than other ways.Compared with other ways,the weight loss rate was evidently reduced,the respiration peak was significantly postpond and the soluble sugar was delayed.With 12d storage,the VCcontent of vacuum group could maintain 50% of its original level,the commodity rate was in that of 95%.Therefore,the optimal pre-cooling method was vacuum cooling.
