This experiment was carried out to investigate changes in lipid contents and fatty acid composition from Korean Native Cattle and porcine muscles during postmortem storage. Experimental animals were normally slaughtered to produce sample from leg(or ham) and loin muscles. Muscles were stored for 0, 2, 4 and 7 day at 4℃ postmortem storage. Fatty acid compositions were analysed by the GLC. The results obtained were as follows: As the storage time passed, the total lipid contents of experimental animals were decreased on 4.5∼4.7% and 3.3∼3.9% in the porcine and Korean Native Cattle muscles, respectively. Fatty acid was identified to eleven in porcine and Korean Native Cattle muscles by the GLC. The highest composition of fatty acid was oleic acid in Korean Native Cattle(40∼43%) and porcine(36∼40%) muscles. The next higher composition of fatty acid were palmitic and stearic acids in Korean Native Cattle (25∼30%, 10∼14%) and porcine (25∼28%, 6∼12%) muscles. The ratios of polyunsaturated and saturated fatty acids (P/S) 0.36∼0.43 in porcine, however, it was found that the P/S ratios of porcine muscles were higher than those of Korean Native Cattle muscles. The ratios between saturated and unsaturated fatty acids composition were 39 to 61 in Korean Native Cattle muscles and 34 to 66 in porcine muscles. The composition of unsaturated fatty acids was higher than that of saturated fatty acid. Although saturated fatty acids increased as the storage time passed, unsaturated fatty acid relatively decreased in experimental animals.

This experiment was carried out to investigate changes in lipid contents and fatty acid composition from Korean Native Goat and chicken muscles during postmortem storage. Experimental animals were normally slaughtered to produce sample from leg(or ham) and loin(or breast) muscles. Muscles were stored for 0. 2. 4 and 7 days at 4 ℃ post-mortem storage. Fatty acid compositions were analysed by the GLC. The results obtained were as follows. As the storage time passed, the total lipid contents of experimental animals were decreased on 2 1-2.5% and 1.8-2.9% in the chicken and Korean Native Goat muscles, respectively. Fatty acid was identified to twelve in Korean Native Goat muscles and ten in chicken muscles by the GLC. The highest composition of fatty acid was oleic acid in Korean Native Goat(47-50%) and chicken(38-43%) muscles. The next higher composition of fatty acid were palmitic and stearic acids in Korean Native Goat (17-19%, 14-18%) muscles, while chicken muscles were palmitic(22-23%) and linoleic acid(15-19%) in chicken muscles. The ratios of polyunsaturated and saturated fatty acids(P/S) 0.72 in chicken, however, it was found that the P/S ratios of chicken muscles were 2-3 times higher than those of Korean Native Goat muscles. The ratios beween saturated and unsaturated fatty acids composition were 41 to 59 in Korean Native Goat muscles and 32 to 68 in chicken muscles. The composition of unsaturated fatty acids was higher than that of saturated fatty acid. Although saturated fatty acids increased a, the storage time passed, unsaturated fatty acid relatively decreased in exprimental animals.
