Abstract
The effect of fatty acids on the characteristic flavor obtained from the Maillard reaction is of particular interest today. Chicken fats were respectively heated at 7 temperatures with an interval increment of 20°C within 60–180°C, while non-heated chicken fat was as a control. Thirteen kinds of fatty acids were identified by gas chromatography-mass spectrometr. (GC-MS). These fatty acids were divided into 3 categories including 7 saturated fatty acids (SFA), 3 monounsaturated fatty acids (MUFA), and 3 polyunsaturated fatty acids (PUFA). Fifty-two kinds of aroma compounds were detected from lipid-Maillard reaction products (MRPs). Analysis of variance (ANOVA) statistical analysis indicated the significant difference (p < 0.001) in six sensory attributes (fatty, meaty, roasty, off-flavor, fresh and overall odor) of MRPs. Partial least square regression (PLSR) was used to detect positive correlation among fatty acids, volatile compounds and sensory attributes. The result showed that 100°C sample (S-100) was correlated with overall flavor and MUFA.
