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.
