| Abstract: | Dependence of processed amount on the vacuum pre-cooling time and weight loss has been investigated for long-stem Chinese cabbages produced in Tianjin. Prior to the vacuum pre-cooling process, the cabbages were wrapped with fresh-keeping packaging film and put into a carton with two sides opening. A comparison study was carried out with unpacked cabbages to analyze the relationship between temperature and position within the carton. The influence of the vacuum pre-cooling of the packing films used on Tianjin's cabbages has been fully analyzed. Based on the experimental results, two correlation expressions have been obtained for the cabbage pre-cooling time and the volume ratio, and the relations between cabbage weight loss and its processed amount. |
