Abstract

This study investigated the effects of cooking conditions on cooking loss, texture, and sensory attributes of glutinous rice chicken (GRC), a popular Chinese poultry dish. We compared the nutritional and sensory profiles of GRC prepared under optimal conditions (GRC-OP) with those of a commercial product (CG). Cooking time, power, and pressure significantly affected the shear force, hardness, and sensory qualities of GRC. The optimal parameters were determined using an orthogonal design: 20 min cooking time, 1000 watts power, and 60 kPa pressure. Gas chromatography/mass spectrometry and E-nose analyses showed that GRC-OP had a volatile profile similar to that of CG but with higher levels of specific compounds, including heptanal, 2-heptenal, octanal, hexanol, octanol, and 1-nonen-4-ol. GRC-OP also exhibited superior umami, salty, and rich tastes, and higher amino acid content, particularly Asp, Glu, Thr, Ser, Ala, Val, Met, and Ile. These findings provide crucial data for optimizing the quality and nutritional value of GRC in the meat industry.
