| 中文摘要: |
| 初步探讨了精油熏蒸在二氧化碳（CO2）抑制黄曲霉菌生长中的增效作用。通过监测黄曲霉菌菌落生长情况，评价了0.01 μL/cm3精油气体与35% CO2、50% CO2和65% CO2气调包装结合的抑菌效果。结果表明，精油熏蒸可显著提升CO2单独气调的抑菌效果，处理6 d时，花椒精油复合50% CO2气调样品的菌落直径较50% CO2气调样品小24%，花椒精油复合65% CO2气调样品的菌落直径较65%CO2气调样品小4%，但抑菌效果与精油成分和CO2体积分数相关，精油复合高体积分数CO2的抑菌效果普遍优于与低体积分数CO2复合。经鉴定，具有显著增效作用的山苍子精油、花椒精油和柠檬精油的主要挥发性物质为β-蒎烯、α-蒎烯和桧烯等。该研究结果为开发利用天然抑菌剂，改善气调包装，延长农产品贮藏期提供了基础。 |

| In this study, the synergic effects of essential oils fumigation combined with carbon dioxide (CO2) modified atmosphere packaging on inhibiting the growth of Aspergillus flavus were preliminarily discussed. The antibacterial effects of 0.01 μL/cm3 essential oil gas combined with 35% CO2, 50% CO2 and 65% CO2 were evaluated by monitoring the growth of A. flavus colonies. The results showed that essential oils fumigation could significantly improve the bacteriostatic effects of CO2 modified atmosphere packaging alone. When treated for 6 days, the colony diameter of prickly ash essential oil combined with 50% CO2 modified atmosphere sample was 24% smaller than that of 50% CO2 air conditioning sample, and the colony diameter of prickly ash essential oil combined with 65% CO2 modified atmosphere sample was 4% smaller than that of 65% CO2 air conditioning sample, but the bacteriostatic effects were related to the essential oil compositions and CO2 concentrations. The antibacterial effects of essential oil combined with high concentrations of CO2 were higher than that with low concentrations of CO2. After identification, the main volatile compounds of litsea cubeba essential oil, prickly ash essential oil and lemon essential oil were β-pinene, α-pinene and sabinene. The results provided a basis for the development and utilization of natural bacteriostatic agents, the improvement of air conditioning packaging and the extension of storage life of agricultural products. |
