Effects of white ginseng on quality characteristics and volatile flavor compounds of roast chickens.

The purpose of this study was to investigate the effects of white ginseng addition (1%, 1.5%, 2%, 2.5% and 3% of meat weight) on the physical and chemical properties of roast chickens. The parameters studied were basic characteristics (salting absorptivity, texture, shear force, pH and sensory evaluation), lipid and protein oxidation, volatile compounds and ginsenoside content. Headspace solid phase micro-extraction and gas chromatography-mass spectrometry (GC-MS) were used to identify the flavor compounds of samples. The changes in physical and chemical properties showed that white ginseng had a positive effect on the quality of roast chickens. The oxidation rate of lipid and protein decreased with the increase of white ginseng addition. In addition, the contents of Ginsenoside Rg1 (Rg1), Ginsenoside Re (Re) and Ginsenoside Rb1 (Rb1) in samples were 5.763 µg/g, 6.047 µg/g and 8.447 µg/g, respectively. Obtained data evidenced the possibility of improvement of the quality characteristics and enrichment of the flavor of roast chickens by adding white ginseng.
