中文摘要: 该文将枸杞在单一等离子体条件下（130 Hz、110 V、70 s）处理并在（3.0±1.0）℃下贮藏，以菌落总数、呼吸强度、可溶性蛋白含量、可溶性固形物含量、抗坏血酸含量、总黄酮含量以及挥发性成分组成等指标分析低温等离子体处理对采后鲜枸杞品质的影响规律。结果表明，与对照组[（3.0±1.0）℃下贮藏]相比，低温等离子体处理对枸杞表面微生物生长有明显的抑制效果，对枸杞的呼吸强度有明显的抑制作用。单一等离子体条件下处理，并在（3.0±1.0）℃贮藏时间可达20 d，比对照组延长了10 d，且枸杞诸多指标的下降速度相对减缓，说明低温等离子体处理对采后枸杞品质变化具有积极作用。

Abstract:In this study，fresh wolfberries were treated under a single cold plasma condition （130 Hz，110 V，70 s） and then stored at （3.0±1.0） ℃. The effects of cold plasma on the postharvest quality of fresh wolfberries were investigated by determining the total number of colonies，respiratory intensity，soluble protein content，soluble solid content，ascorbic acid content，total flavonoid content，and volatile odor components. The results showed that，compared with the control group stored at （3.0±1.0） ℃，cold plasma significantly inhibited the growth of microorganisms on the surface of wolfberries and effectively reduced their respiratory intensity. Wolfberries treated under the single plasma condition and stored at （3.0±1.0） ℃ had a shelf life of up to 20 days，which was 10 days longer than that of the control group. Additionally，the decline rates of various quality indicators of wolfberries were relatively slowed down. These findings indicate that cold plasma treatment exerts a positive effect on delaying the postharvest quality deterioration of fresh wolfberries.
