In order to investigate the effect of heating treatment on pork quality, weight loss through cooking, Warner-Braztler shear force (WBS), shape, color and pH of pork loins were measured after they were subjected to heating treatment at 25,50,60,80 ℃ and 100 ℃, respectively. Resulted indicated that higher temperature could result in increase of weight loss through cooking, WBS and pH value, shrinkage of pork loins, color alteration from red to white or gray.
