烘烤条件对压榨奇亚籽油中苯并\[a\]芘含量的影响Effect of roasting conditions on benzo(a)pyrene content in pressed chia seed oil
为探索不同烘烤条件下奇亚籽油中苯并\[a\]芘含量的变化规律,在不同的烘烤温度(60、100、140、180 ℃)和烘烤时间(10、30、50、70、90 min)下烘烤奇亚籽,采用液压压榨制备奇亚籽油。观察奇亚籽油色泽,并记录其气味。以MIL-101(Cr)为分散式固相萃取材料,采用分散式固相萃取-高效液相色谱-荧光检测器对苯并\[a\]芘进行定量检测。结果表明:烘烤条件对奇亚籽油的色泽、气味影响较大;随着烘烤温度的升高及烘烤时间的延长,奇亚籽油中苯并\[a\]芘含量逐渐升高,且烘烤温度越高、烘烤时间越长,苯并\[a\]芘含量增幅越大。参考GB 2762—2017及欧盟No 835/2011...
