|Abstract:||Selection of the agents for reducing water activity (aw) of Brassica parachinensis with intermediate moisture contents (23.01% w.b.) and the storage stability at 4, 20, and 37°C using different packaging methods were studied. The aw-lowering agent for the dehydrated Brassica parachinensis with intermediate moisture was optimized: 8% glucose, 4% lactose, 2% sodium chloride, and 7.5% maltodextrin. Storage experiments showed that vacuum packaging or storage in darkness can reduce the loss of ascorbic acid and chlorophyll and delay the browning process. The overall quality of dehydrated Brassica parachinensis with intermediate moisture stored at 4° was better than at 20 and 37°C. Microbial analysis showed that an aw value of 0.69-0.70 was safe for dehydrated Brassica parachinensis with intermediate moisture.|
