摘要
[目的]利用低毒纳米硒对小白菜进行补硒。[方法]利用水浴法在表面活性剂辅助下制备表征纳米硒;将红色纳米硒用于小白菜补硒试验,并使用邻苯二胺紫外分光光度法测定样本含硒量、回收率和稳定性,分析低毒纳米硒对小白菜进行补硒的可行性。[结果]经过纳米硒补硒的小白菜含硒量平均为5.326μg/g,比未经补硒的小白菜含硒量提高了6倍多。试验回收率在97.84%～100.47%,样本在24 h内稳定,补硒效果明显。[结论]该研究为富硒蔬菜的开发与研究提供了有益的参考。
[Objective]The low toxicity nano-selenium was added in cabbage.[Method]The nano-selenium was prepared under the surfactant copy by means of the water-bathing method and the product of red nano-selenium was experimented for its addition for cabbage.And the content of selenium in sample,its recovery and stability were tested with o-phenylene-diamine UV spectrophotometry and the feasibility of low toxicity nano-selenium added in cabbage was analyzed.[Result]The average content of selenium in the treated cabbage was 5.326 μg/g,which was 6 times higher than that of CK.The recovery of selenium was 97.84%-100.47%,the sample could be was stabilized within 24 hours,which effect was obvious.[Conclusion]The useful reference for the development and research on selenium-richening vegetable was provided.
