  • This study was conducted to determine the nutritional characteristics of horsemeat and bone meal in comparison with those of beef and pork presented by Dietary Reference Intakes For Koreans. Longissimus muscle and large metacarpal bone samples were collected from 20 fattened Jeju horses. Muscle samples were subjected to proximate analysis, assays for fatty acid profile and minerals, and bone samples to mineral assays. Horsemeal had similar levels of protein (21.1 vs 21.0 or 21.1%) and lower levels of fat (6.0 vs 14.1 or 16.1%) compared with beef or pork, respectively. Horsemeat had much higher levels of palmitoleic (8.2 vs 4.4 or 3.3%) and $\alpha-linolenic$ (1.4 vs 0.1 or 0.6%) acids than beef or pork, respectively. Linoleic acid was much higher in horsemeat (11.1%) and pork (10.1%) than in beef (1.6%). PUFA:SFA and n-6:n-3 ratios in horsemeat were 0.29 and 10.2, respectively. There were no big differences in mineral contents between horsemeat, beef and pork. For daily recommended mineral intakes of male adults (Dietary Reference Intakes For Koreans), phosphorus, sodium, potassium, iron, zinc and copper can be provided up to 24, 2.5, 6.7, 21, 26 and 40%, respectively, by 100 g raw horsemeat, but calcium and manganese levels are negligible. Horse cannon bone had much higher mineral contents especially in calcium (10,193 mg/100 g), phosphorus (5,874 mg/100 g) and copper (0.79 mg/100 g). Thiamin, riboflavin, niacin and retinol contents were 0.20, 0.21, 1.65 mg/100 g and $30{\mu}g/100g$, respectively. But ascorbic acid and beta-carotene were not detected. Our data demonstrated that higher levels of palmitoleic and $\alpha-linolenic$ acid in horsemeat than in beef and pork may be beneficial for human health. Horsemeat and bone meal are a good source of some minerals and vitamins.

  • Electron spin resonance (ESR) spectroscopy was used to detect irradiated meat containing bones (chicken, pork and beef), to investigate the effect of irradiation dose on the ESR signal intensity and to identify the stability of radicals under 9 weeks of storage. Chicken, pork and beef were irradiated with doses 0, 1, 3, 5 and 7 kGy at room temperature using a Co-60 irradiator. Bones were pieced and dried, which were placed in a quartz tube within an Electron paramagnetic resonance (EPR) spectrometer resonator cavity. The irradiated bone presented an asymmetric absorption in shape, different from that of a non-irradiated one. The signal intensity of smaller animals are lower than larger species. Variation was observed between samples of the same species depending on the calcification status of the bone. Moreover different irradiation doses produced different signal areas that make possible to estimate the absorbed dose of treated meat. The ESR signal stability after irradiation was stable in even after a 9 week storage at room temperature.

  • To identify irradiated foods, studies have been carried out with electron spin resonance (ESR) spectroscopy on bone containing foods, such as chicken, pork, and beef. Bones cleaned, pieced and dried were irradiated with doses of 0, 1, 3, 5 kGys using a $Co^{60}$ irradiator. The bones were placed in a resonant quartz tube with an internal diameter of about 4.0 mm within the Bruker Win-ESR spectrometer, and the intensity of the ESR signal could be quantified by double integration of the first derivative spectrum. The irradiated bone presented an asymmetric absorption in shape, different from that of an unirradiated one. It could be possible to detect at doses lower than 1 kGy below the dose employed commercially (3 kGy) in the case of irradiated chicken bone. The signal intensity was greatest in the beef bone, intermediate in the pork bone and lowest in the chicken bone; it was normally lower for smaller animals than for larger species, and small variations were observed between samples of the same species. The intensity of the signal induced in bones increased linearly with irradiation doses in the range of 1.0 kGy to 5.0 kGy, and it was possible to distinguish between samples given low and high doses of irradiation. The signal stability for 6 weeks made them ideal for the quick and easy identification of irradiated meats.

  • The CLA used to add in diet was chemically synthesized by alkaline isomerization method with corn oil. To investigated the effects of conjugated linoleic acid(CLA) added diet feeding on CLA accumulation and blood characteristics of pork, a total of 64 Landrace was fed both CLA-free and CLA-added(0.3, 0.6 and 0.9%) diet for 1∼4 weeks. Cholesterol compositions in blood and CLA contents and fatty acid compositions of loin, belly, bone and skin were determined at 1, 2, 3 and 4 weeks after CLA added at fed. The HDL content in blood of all treatments was higher(P<0.05) than that of control and that of treatment 3 was higher(P<0.05) than that of other treatments among the CLA feeding periods. Palmitic, stearic and linolenic acids composition of loin and belly was increased but oleic, linoleic and arachidonic acids composition of them was decreased according to increasing the CLA feeding periods. CLA contents of loin and belly were higher than that of control and increased according to increasing the quantity of CLA and CLA feeding periods. CLA contents of bone and skin were higher than that of control, too. CLA content of skin was higher than that of bone. It was suggested that CLA could be accumulated in loin, belly, bone and skin by dietary CLA supplementation, and the CLA concentration and fatty acid composition in muscle could be affected by CLA level in diet and feeding period.

  • The effect of boiling with apple vinegar and citric acid on the dissolution of Ca, Mg, and P out of pork rib bone during stew preparation was investigated. As the concentration (0, 1, 2. 4%) of apple vinegar and citric acid increased, the amount of Ca, Mg, and P dissolved out of the rib bone increased compared with the control. The increase in boiling time(3, 6, 9, 12 hour) also showed the same result. Between the two acid condiments citric acid extracted more Ca, Mg, and P than the apple vinegar at the same concentration. The pH of the pork rib bone stew added with the acid condiments increased gradually during the boiling process. Between the two acid condiments the apple vinegar extracted more amino acids and protein than citric acid at the same concentration.

  • Two kinds of composite seasoning products (beef broth powder, polk bone extract powder) were used for a detection trial of gamma irradiation treatment up to 10 kGy by analyzing photostimulated luminescence (PSL), electron spin resonance (ESR) and thermoluminescence(TL). PSL results showed that the photon counts of non-irradiated samples were lower than 700, while those of irradiated samples were higher than 5000, which makes it possible to screen irradiated composite seasoning products at 1 kGy or over from the non-irradiated control. ESR signals measured for both irradiated samples were not irradiation-specific, even though they were dose dependent in the signal intensity. Radiation-induced TL glow curves were found in irradiated beef broth powder and furthernmore, TL ratio $(TL_4/TL_2)$ obtained by a re-irradiation step could verify the detection result of TL1 glow curves, showing ratios lower than 0.05 in the non-irradiated sample and higher than 1.00 in irradiated ones.

  • Vitamin and mineral deletion from swine diets can result in reduced growth if done during the period wher muscle and bone development is occurring. Several of the vitamins and minerals decline in the serum during the starter period, suggesting a higher dietary inclusion may be necessary postweaning. Vitamin research with grower-finisher pigs is limited, but results suggest that rapidly growing lean pigs may have a higher dietary requirement for the B vitamins. Several studies have suggested that early weaning and pigs of a lean genotype may have a dietary requirement for vitamin C, CI and Cr. High dietary vitamin E levels are fortified in the diet and seems to be effective in preventing mulberry heart problems in weanling and grower pigs. Organic Se is more effectively retained in muscle tissue than inorganic Se, approximately 20% less is excreted, but the bioavailability of organic Se for glutathione peroxidase activity is only 80 to 90% to that of sodium selenite. The active form of thyroxine (T4) is dependent upon a Se containing enzyme. Withdrawal of vitamins and minerals during the latter part of the finisher period has not affected pig performance responses, but studies with poultry suggest that the vitamin content of the meat may be reduced if the vitamins are withdrawn prior to marketing. High levels of vitamin E have been shown to improve pork quality, by reducing drip loss. Studies with vitamin C and Se have suggested that they may also be involved in pork quality.

  • This study was designed to investigate the characterization of black goat meat and bone beverage containing honey of red ginseng. The crude proteins and moisture contents of black goat meat were higher than those of pork and beef, but the crude lipid content of black goat meat was lower than that of those. The potassium content of black goat meat was lower than that of chicken, but similar to the pork and beef. The sodium content of black goat meat was lower than that of chicken, pork and beef. The result of the sensory evaluation of black goat meat and bone beverage added honey with red ginseng by 25 panels, was that the beverages added $7.5\%\;and\;8.0\%$ honey with red ginseng were better than any other beverages. Thus, the results suggest that the black goat meat bone beverage added honey with red ginseng could be one of valuable drinks.
