几种蔬菜真空预冷的对比实验研究

Comparative Experimental Study on Vacuum Pre - cooling for Several Vegetables

预冷是蔬菜冷链的首要环节,对蔬菜保鲜至关重要。以大白菜、黄瓜、生菜和香菇四种蔬菜作为实验对象,得到了这几种蔬菜的真空预冷实验数据,并对实验数据进行对比分析,为今后真空预冷技术的推广应用提供参考。

Pre- cooling is the first working procedure after vegetable is harvested. It is important to keep vegetable＇ s freshness. In our research, Chinese cabbage, cucumber, lettuce, and forest mushroom were used for experimental samples. Their experimental data of vacuum pre- cooling were obtained and compared..
