摘要

冷等离子体技术已在食品工业中用于表面净化。因此，本研究调查了低压冷等离子体（CP）处理对海藻酸钠涂层和包装的“蒙特利”草莓的净化效果。在80kV下进行冷等离子体处理5 min。处理后，将样品储存在5 持续6天，并定期取样进行微生物和视觉质量分析。结果表明，未经CP处理的包衣草莓装在蛤壳托盘中，在储存结束时比其他处理和对照具有更好的外观。与对照组相比，在草莓上施用藻酸钠涂层和CP处理可使储存结束时的酵母和霉菌数量减少≈2 Log（p < 0.05）。

Impact of cold plasma-mediated treatment on coated and packaged ‘Monterey’ strawberries during cold storage

Cold plasma technology has been used within the food industry for surface decontamination. Therefore, this study investigated the efficacy of low-pressure cold plasma (CP) treatment to decontaminate sodium alginate-coated and packaged ‘Monterey’ strawberries. Cold plasma treatment was carried out at 80 kV for 5 min. After treatments, samples were stored at 5 °C for six days, and samples were taken at regular intervals for microbial and visual quality analysis. Results obtained showed that coated strawberries without CP treatment packed in clamshell trays had a better visual appearance than the other treatments and control at the end of storage. Application of sodium alginate coating and CP treatment on strawberries resulted in ≈2 Log reduction in yeast and mould counts at the end of storage in comparison to the control (p < 0.05).
