The spectrophotometry,gas chromatography-mass(GC-MS) and high performance liquid chromatography(HPLC) were used to measure the contents of nitrite,trans-oleic acids(C18:1 trans-9) and polycyclic aromatic hydrocarbon(PAHs) respectively. The results showed that the content of nitrite in the processes of 2 min and of 3 min were lowest. There were no significant differences in C18:1 trans-9 content for pan-frying time(p >0.05). The contents of phenanthrene,pyrene and dibenz[a,h] anthracene in the processes of 2 min and 3 min pan-frying were lower(p <0.05). For frying,the contents of nitrite,C18:1 trans-9,pyrene,benzo[k] fiuoranthnen,benzo[a] pyrene and dibenz[a,h] anthracene in the process of 3 min were lowest respectively(p <0.05). For broiling,the content of nitrite in the process of 160 ℃ was lowest(p<0.05). The content of C18:1 trans-9 in the processes of 160 ℃ and 180 ℃ were lower. The contents of naphthalene,phenanthrene and benzo[a] pyrene in the process of 160 ℃ were lower than those in 180 ℃,and the contents of phenanthrene,chrysene,benzo[k] fiuoranthnen and benzo[a] pyrene were lower than those in 200 ℃(p <0.05). A comprehensive analysis indicated that the three high-temperature cooking methods had a great influence on the hazardous substances of goat meat. At the temperature of 226~228 ℃,the goat meat were pan-fried for 2~3 min and fried for 3 min respectively,and broiled for 40 min under the temperature of 160 ℃,which had a lower hazardous substances %K 1 trans-9 %K PAHs %U http://spyswjs.cnjournals.com/spyswjs/ch/reader/view_abstract.aspx?file_no=201810009&flag=1
