ZnO@ZIF-8对稻谷储藏过程中主要品质指标的影响研究OA

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 verified 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.
