高仿野生条件养殖的野香猪体脂肪、胶原蛋白、氨基酸及硒含量分析

    Analysis on the Contents of Body Fat, Collagen, Amino Acid and Selenium in Wild Pigs Raised Under Highly Simulated Wild Conditions

    • 摘要: 【目的】研究高仿野生条件下养殖的野香猪的肉质品质。【方法】用索氏提取法、羟脯氨酸比色法和邻苯二胺紫外分光光度法及氨基酸自动分析仪对野香猪的脂肪、胶原蛋白、氨基酸及硒含量进行检测。【结果】野香猪的肌肉(前后腿肉等量混合)、皮(含皮下脂肪)、大肠和小肠的脂肪含量分别为 29.8、417.6、124.9、15.6 mg/g,胶原蛋白含量分别为 9.03、312.21、18.36、19.58 mg/g;肌肉的门冬氨酸、谷氨酸、丙氨酸含量分别为 13.5、23.7、8.4 g/kg;硒含量为大肠 0.78 mg/kg,小肠 0.77 mg/kg,皮肉混合组 0.70 mg/kg;而饲用青料硒含量为 0.43~1.06 mg/kg。【结论】野香猪肉中脂肪含量适中,胶原蛋白、氨基酸及硒含量丰富。

       

      Abstract: 【Objective】 The study was conducted to understand the meat quality of wild pigs that raised in highly simulated wild conditions. 【Method】Approaches of soxhlet extraction, hydroxyproline colorimetry, o-phenylenediamine ultraviolet spectrophotometry and amino acid automatic analyzer were used to detect the contents of fat, collagen, amino acid and selenium in wild pigs cultured under highly simulated wild condition. 【Result】 The results showed that the fat content of muscles (mixed with equal mass of meat from the fore bock and back legs ), skin (including subcutaneous fat), large intestine and small intestine were 29.8, 417.6, 124.9 and 15.6 mg/g, respectively, and the collagen content of them were 9.03, 312.21, 18.36 and 19.58 mg/g, respectively. The contents of aspartic acid, glutamic acid and alanine in muscle were 13.5, 23.7 and 8.40 g/kg, respectively. The contents of selenium in large intestine, small intestine and the mixed meat and skin were 0.78 , 0.77 and 0.70 mg/kg, respectively. While the selenium content of green fodders was 0.43-1.06 mg/kg. 【Conclusion】The fat content of wild pork was moderate and was rich in collagen, amino acid and selenium.
