摘要
探讨经过臭氧处理的油菜籽品质变化。将当年新收获的油菜籽储藏在不同温度条件下,定时对油菜籽用不同质量浓度的臭氧处理,每10d对油菜籽的发芽率、含油量和菌落总数等品质指标进行1次检测。结果表明:臭氧质量浓度为0μg/mL(对照)时,发芽率降低最为明显,温度、时间和臭氧质量浓度对发芽率影响极显著(P<0.01),且交互作用明显;不同储藏因素对油菜籽含油量影响大小顺序为储藏时间>储藏温度>臭氧质量浓度;不同质量浓度臭氧处理均可以有效抑制霉菌的增长,且在高温条件下抑制效果最为明显。
Newly harvested rapeseed samples were stored under different temperatures and regularly treated with different concentrations of ozone.Germination percentage,oil content and mold count of treated rapeseed samples were determined once every 10 days during the storage.The control without ozone treatment showed the most substantial reduction in germination percentage.Storage temperature and time as well as ozone concentration had highly significant effect on germination percentage of rapeseed（P 0.01）,with significant interactions.Storage time had the most significant effect on oil content of rapeseed,followed by storage temperature and ozone concentration.All investigated ozone concentrations could effectively inhibit mold growth,especially at high storage temperatures.
