摘要： The study examined the impact of combining slightly acidic electrolyzed water (SAEW) with nisin on the browning of fresh-cut lettuce stored at 10 degrees C. Results indicated that the use of 50 mg L-1 SAEW and 300 mg L-1 nisin (S+N) notably outperformed other treatments in reducing browning. By day eight of storage, the browning index in the S+N group was 78.0 % lower compared to the control. Additionally, the S+N treatment significantly lowered the browning degree, a* and b* values, and the activity of enzymes such as SOD, PPO, POD, and PAL, while maintaining higher L* values and chlorophyll content. The combination also reduced total phenolic content and malonaldehyde (MDA) levels more effectively than the control. Overall, the SAEW and nisin combination proved to be effective in delaying browning, extending shelf life, and shows promise for practical application in fresh-cut lettuce preservation.
