Heterocyclic amines (HAs) are a class of compounds containing unsaturated double bonds with their ring structure composed of carbon, hydrogen and nitrogen. The HAs are usually formed during high temperature processing of protein rich foods. The objective of this study is to evaluate different processing methods for reduction of HAs in fried pork fiber. A quick and simultaneous analysis method which coupled with QuEChERs and LC-MS-MS also be developed for determining 20 types of HAs in fried pork fiber. Results showed that HAs contents in fried pork fiber increased along with increasing cooking time and temperature. Moreover, fried pork fiber show high levels of harman with the amount of total HAs ranging from 103.19-661.38 ng/g and their levels decreasing in the following order: nor Harman >8-MeIQx>IQx>PhIP>Trp-P- 2>Phe-P-1>IFP>MeAαC>MeIQ. However, DMIP, Glu-P-2, Iso-IQ, IQ, Glu-P-1, IQ [4, 5-b], 7, 8-DiMeIQx, 4,8-DiMeIQx, Trp-P-1 and AαC were not detected. Half proportion of soy sauce in fried pork fiber effectively reduced the amount of HAs, while reducing sugar to half and increased the formation of HAs, with reducing of both sugar and soy sauce proportion to half showing no significant effects.
