摘　　要：为研究低温等离子体技术对番茄采后贮藏品质的影响,以番茄为原料,采用不同强度(30、60kV)低温等离子体处理番茄5min,每隔7 d取样,测定其硬度、呼吸强度、失重率、可溶性固形物、可滴定酸、色差、总酚、丙二醛、菌落总数等指标。结果表明:60 kV处理番茄效果较好,可维持较好的硬度,保持较高的可溶性固形物、可滴定酸、总酚含量,延缓呼吸速率的升高,抑制丙二醛和微生物的增加,保持较低的失重率,能有效延长货架期。The effect of cold plasma on the storage quality of postharvest tomatoes was studied.Tomatoes were treated with different intensities(30 kV and 60 kV)of cold plasma for 5 min,and sampling was conducted at 7-day intervals for the determination of hardness,respiration intensity,weight loss,soluble solids,titratable acid,color difference,total phenols,malondialdehyde,and total bacterial colonies.The results showed that 60 kV treatment was effective in maintaining the hardness,soluble solids,titratable acids,and total phenols of tomatoes.Moreover,it delayed the increase in respiration rate,inhibited the increases in malondialdehyde and microorganisms,and maintained low weight loss,thus extending the shelf life of postharvest tomatoes.
