| 摘 要： | 采用动植物原料制备出了新型富硒功能保鲜剂(CN-1),并利用果蔬的呼吸作用,使果蔬在保鲜的过程中富硒.实验测定了脐橙在储藏和保鲜过程中硒含量的变化,考察富硒功能保鲜剂对水果脐橙富硒效果.结果表明,采用富硒功能保鲜剂浸泡的脐橙能明显提高脐橙的果肉硒含量,且随着富硒保鲜剂中硒浓度的增大,果肉富硒含量也增大.按照国家标准对富硒食品硒含量的要求及食品中硒的限量标准,得出富硒功能保鲜剂中最佳硒浓度为180 mg/L.所制备出的富硒保鲜剂为天然生物保鲜剂且可人为控制硒的含量,不会出现硒超标及环境污染等安全性问题.富硒功能保鲜剂既可提高水果中硒含量水平,又可延长水果的销售时间;具有良好的社会效应和经济价值.
