摘要
We investigated nutritional characteristics and active components in the liver of WagyuxQinchuan cattle and Qinchuan cattle produced in Shaanxi (China). We observed significant differences (p<0.05) in the proximate composition of protein, fat, carbohydrate, total energy, and glycogen. WagyuxQinchuan cattle liver showed higher (p<0.05) sodium, iron, zinc, and selenium concentrations than Qinchuan cattle liver. The amino acid composition of WagyuxQinchuan cattle liver was richer (p<0.05) in: 13 types of amino acids, with the exception of Asp (10.06%), Val (5.86%), and Met (1.72%). Total essential amino acids accounted for almost half the composition (39.69%) in WagyuxQinchuan cattle liver. WagyuxQinchuan cattle liver had loWer (p < 0.05) levels of monounsaturated fatty acids (18.2%), but higher (p < 0.05) levels of polyunsaturated fatty acids (35.11%), compared with Qinchuan cattle liver (23.29% and 28.11%, respectively). The thrombogenic index was higher in Qinchuan cattle liver (0.86) than in WagyuxQinchuan cattle liver (0.70), and the glutathione (38.0 mg/100g) and L-carnitine (2.12 mu M/g) content was higher (p < 0.05) in WagyuxQinchuan cattle liver than in Qinchuan cattle liver (29.8 mg/100g and 1.41 mu M/g, respectively). According to the results obtained, the liver of WagyuxQinchuan cattle, which is insufficiently used, should be increasingly utilized to improve its commercial value.
