Abstract
Four different extraction and purification methods were evaluated to determine the heterocyclic amines (HCAs) in fried pork patties. Pork patties were cooked in the teflon-coated electric frying pan at 230°C for 8 min per side. HCAs in the fried pork patties were extracted and purified using four different solid-phase extraction (SPE) methods and quantitated by LC-MS (API-ESI). Recovery of four different extraction and purification methods was evaluated by comparing the HCAs amounts quantified by the standard addition method. Validation of extraction and purification methods for fried pork patties was determined to establish accurate sample preparation. The recoveries of HCAs from different SPE methods were calculated. The recovery yields were 15.7-68.7% (Polar amine group) and 25.0-74.7% (less-polar amine group) in method A. Method D provided recovery yields ranging from 14.1% to 68.7% in polar amine groups and from 3.0% to 72.3% in less-polar amine groups, respectively. Modified procedures of Method A and D were the most suitable extraction and purification method for HCAs analysis from fried pork patties.
