Dimethyl dicarbonate(DMDC)is a safe and useful disinfectant widely used in beverage and wine industry.The effect of DMDC (200 mg/l) treatment on fresh-cut carrot was determined in this study.The results showed that DMDC treatment reduced significantly (p < 0.05) the total aerobic plate count (TAPC) by 3.01 log10 (cfu/g) and the count of total yeasts and moulds by 3.43 log10 (cfu/g) in fresh-cut carrot respectively compared with control (tap water washing).In addition, DMDC treatment could also inhibit the activity of polyphenol oxidase (PPO) and peroxidase (POD) and be beneficial to maintaining the level of vitamin C, the color quality and hardness of fresh-cut carrot during storage at 10℃.There was no significant influence on the β-carotene content of fresh-cut carrot treated by DMDC.Therefore, DMDC was a new effective disinfectant in fresh-cut carrot.

本文旨在研究1-MCP和加压氩气联合处理对莲蓬保鲜效果的影响.结果显示:相对于单独用1-MCP熏蒸处理,1μL/L 1-MCP和5MPa氩气联合处理能够明显延缓鲜莲蓬成熟衰老.1μL/L 1-MCP和5MPa氩气联合处理推迟了呼吸高峰的出现并降低了呼吸速率的峰值,减缓了水分的损失;联合处理的莲蓬不仅具有更低的脆度,而且维生素C、可溶性固形物含量更高.同时,联合处理降低了鲜莲蓬的黄化速率.研究结果表
