Rapeseed (Brassica napus L.) oil is mostly refined oil (RO). However, with increasing interest in health, the consumption of cold-pressed oil (CPO) without chemical refining is increasing in Korea. In this study, quality characteristics of CPO from rapeseed varieties ‘Jungmo7001’, ‘Jungmo7002’, ‘Jungmo7003’,and ‘Yuryeo’were evaluated and compared with RO, a commercial product. L-value and a-value were lower while b-value was significantly higher for CPO than those for RO. Analysis of fatty acid compositions of each oil revealed that CPO from ‘Yuryeo’contained the highest oleic acid at 74%. Analyses of contents of bioactive compounds in CPOs and RO revealed that contents of tocopherol, β-carotene, and canolol were the highest in CPOs from ‘Jungmo7003’, ‘Jungmo7002’, and ‘Jungmo7001’at 55.5, 0.3, and 0.2 mg/100 g, respectively. In addition, CPOs contained higher contents of bioactive compounds than RO, suggesting that CPO could provide health benefits. The induction period of CPOs measured using Rancimat were 9∼52% longer than that for RO, indicating that CPOs had a higher oxidative stability under given conditions. These results could be used to obtain basic data on quality of domestic rapeseed varieties.
