Abstract: In this experiment, the vacuum pre-cooling experiments on the three types of vegetables have been conducted and the comparisons of temperatures among Chinese cabbage, cabbage and potato at different inside depths versus time and the effects of the pressure in vacuum container on vacuum pre-cooling for different vegetables have been carried out. Besides, the effects of the vegetables covered with water or not on the weight loss of vegetable has also been assayed.
