This study was performed to evaluate the antioxidative potential and quality of the breast meat of broiler chickens fed a dietary medicinal herb extract mix (MHEM, consisting of mulberry leaf, Japanese honeysuckle, and goldthread at a ratio of 48.5:48.5:3.0). A total of 480 one-day-old male Cobb broiler chicks were randomly allotted to 12 pens, with 40 birds per pen (replicate), and reared for 35 d. Dietary treatments consisted of a corn-soybean meal basal diet (control); a basal diet with 0.3%

Three experiments were conducted to develop a sensitive and reliable fluorometric thiobarbituric acid (TBA) reactive substances (TBARS) method to determine lipid oxidation products in meat. The first study was conducted to find the optimum sample preparation conditions for meat in the fluorometric method. The second study was to compare the original and the modified methods by using meat and blood samples. The modified fluorometric method was compared with a conventional spectrophotometric metho

The aim of this study was to examine the effect of chicken line on the contents of endogenous compounds, including carnosine, anserine, creatine, and inosine 5'-monophosphate (IMP), in breast and thigh meats from 5 lines of Korean native chicken for the development of high-quality meat breeds. Additionally, the effects of sex (male or female) and meat type (breast or thigh meat) were examined. In total, 595 F1 progeny [black: 90 (male: 45, female: 45); gray-brown: 110 (male: 52, female: 58); red

ABSTRACT Oil emulsions containing amino acids, glutathione, bovine serum albumin, gelatin, or myofibrillar proteins were prepared. The emulsions were irradiated at 0, 2.5, 5.0, or 10.0 kGy absorbed doses and analyzed for volatile compounds. Irradiation increased the production of aldehydes (for example, hexanal, heptanal, octanal, and nonanal) indicating that lipid oxidation of oil emulsion was accelerated by irradiation. Irradiation produced, by radiolytic degradations, new volatile compounds f
