The quality changes of lotus root prefabricated dishes under low pressure was studied.The results showed that low pressure inhibited respiration rate,activity of PAL and the rising of content of total phenols,and delayed the occurrence of browning.The reduction of the soluble solid content,the titratable acid content and the hardness were slowed.Low pressure kept the fresh-cut lotus root better quality,and improved the quality of lotus prefabricated dishes.
