Cold plasma is increasingly under research for decontamination of foods, especially fresh fruits and vegetables. The effect of cold plasma on food quality, however, remains under researched. This study investigates the effects of cold plasma generated within a sealed package from a dielectric barrier discharge on the physical quality parameters and respiration rates of cherry tomatoes. Respiration rates and weight loss were monitored continuously, while other parameters are reported at the end of storage period. Differences among weight loss, pH and firmness for control and treated cherry tomatoes were insignificant towards the end of storage life. Changes in respiration rates and colour of tomatoes were recorded as a function of treatment, which were not drastic. The results implicate that cold plasma could be employed as a means for decontamination of cherry tomatoes while retaining product quality.
冷等离子体在食品去污方面的研究越来越多，尤其是新鲜水果和蔬菜。然而，冷等离子体对食品质量的影响仍有待研究。本研究调查了在密封包装内通过介质阻挡放电产生的冷等离子体对樱桃番茄物理质量参数和呼吸速率的影响。连续监测呼吸速率和重量损失，而其他参数在储存期结束时报告。在储存期结束时，对照和处理后的樱桃番茄在重量损失、pH值和硬度方面的差异不显著。记录了番茄呼吸速率和颜色随处理的变化，这些变化并不剧烈。结果表明，冷等离子体可以作为一种在保持产品质量的同时对樱桃番茄进行去污的手段。
