稻谷是我国三大主粮之一，也是我国重要的储备粮种，高温高湿条件下稻谷易发生霉变与品质劣变。本研究在制备ZnO@ZIF-8核壳纳米复合材料基础上，在35℃、35 d模拟储藏条件下，探究了ZnO@ZIF-8不同添加质量浓度对稻谷储藏过程中霉菌菌落总数、出糙率、脂肪酸值等微生物及主要品质指标的影响。结果表明，ZnO@ZIF-8的作用呈现明显质量浓度依赖性，高质量浓度添加抑菌效果最优，霉菌菌落总数较对照组降低43.6%，但对稻谷生理指标的影响也最大；低质量浓度ZnO@ZIF-8处理，在抑制霉菌生长的同时，能够减缓稻谷出糙率的下降与脂肪酸值的升高，综合应用效果最优。本研究证实了ZnO@ZIF-8对稻谷储藏中霉菌的抑制和品质指标的保护作用，为新型绿色稻谷储藏防护材料的开发与应用提供了理论依据与数据支撑。
Abstract：Paddy is one of the three major staple foods and a crucial reserve grain species in China. It is highly susceptible to mildew and quality deterioration under high temperature and high humidity conditions. Based on the preparation of ZnO@ZIF-8 core-shell nanocomposite,the effects of different addition concentrations of ZnO@ZIF-8 on microbial indicators(represented by total mold colony count) and key quality indicators(including husked rice yield,fatty acid value,et al.) of paddy under simulated storage at 35 ℃ for 35 days were investigated. The results indicated that the effects of ZnO@ZIF-8 exhibited significant concentration dependence. The high-concentration treatment achieved the optimal antibacterial effect,with the total mold colony count reduced by 43.6% compared with the control,but it also exerted the most severe impact on the physiological indicators of paddy. In contrast,the low-concentration treatment of ZnO@ZIF-8 could inhibit mold growth while effectively slow down the decrease of husked rice yield and the increase of fatty acid value,presenting the best comprehensive application performance. This study verifed the mold inhibitory effect and quality protective effect of ZnO@ZIF-8 during paddy storage,providing theoretical basis and data support for the development and application of novel green protective nanomaterials for paddy storage.
