摘要

用,60,Co γ射线辐照处理市售大虾，辐照剂量分别设定为1、3、5和7 kGy，用弗罗里硅土固相萃取法净化索氏法提取的脂肪，通过GC-MS检测试样液中挥发性碳氢化合物的种类和含量。结果表明，辐照组中C17:1和C16:1两种物质是辐照后新产生的碳氢化合物，回收率分别为78.2%和88.06%，且随辐照剂量的增加，两种物质的含量逐渐增加。

Abstract

The shrimp were irradiated by ,60,Co γ rays at the dose of 1, 3, 5, and 7 kGy. The shrimp was firstly Soxhlet extracted and then purification of the shrimp oil was carried out by solid-phase extraction column to remove the fat and pigment. The hydrocarbons contained in the shrimp were determined by GC-MS among irradiated and unirradiated samples. The results show that C17:1 and C16:1 produces were the new types of hydrocarbons in irradiated shrimp with recovery of 78.2% and 88.06%, respectively. Content of C17:1 and C16:1 increased with the increase of the absorbed dose.
