【摘要】：試驗旨在研究南陽黑豬脂肪酸組成及含量,以期為中國地方豬種遺傳資源的保護及開發(fā)利用提供理論依據(jù)。以南陽黑豬和大白豬為研究對象,每品種豬各12頭,測量背最長肌脂肪酸含量及種類,以脂肪酸種類及數(shù)量、單不飽和脂肪酸(monounsaturated fatty acid,MUFA)、多不飽和脂肪酸(polyunsaturated fatty acid,PUFA)、飽和脂肪酸(saturated fatty acid,SFA)、12-16碳飽和脂肪酸(飽和脂肪酸1,SFA1)、其他飽和脂肪酸(飽和脂肪酸2,SFA2)、不飽和脂肪酸(unsaturated fatty acids,UFA)、SFA2/SFA1、PUFA/MUFA、必需脂肪酸(essential fatty acid,EFA)、共軛亞油酸(conjugated linoleic acids,CLA)、PUFA/SFA、ω-6PUFA/ω-3PUFA等為指標,從營養(yǎng)、健康、風(fēng)味及儲存方面綜合評價兩個豬種豬肉脂肪酸品質(zhì)。結(jié)果顯示,兩個豬種背最長肌中共檢出30種脂肪酸,其中23種脂肪酸在兩個豬種間有顯著或極顯著差異(P0.05;P0.01);除SFA2/SFA1和ω-6PUFA/ω-3PUFA外,南陽黑豬其他指標均高于大白豬;SFA1、MUFA、PUFA、SFA、UFA、UFA/SFA、SFA2/SFA1、PUFA/MUFA、EFA、CLA、PUFA/SFA、ω-6PUFA/ω-3PUFA 11個指標在兩個豬種間存在顯著或極顯著差異(P0.05;P0.01),SFA2和PUFA/MUFA在兩個豬種間無顯著差異(P0.05)。綜合以上結(jié)果,南陽黑豬肌肉脂肪酸品質(zhì)總體優(yōu)于大白豬。
[Abstract]:The aim of the experiment was to study the fatty acid composition and content of Nanyang black pig in order to provide theoretical basis for the protection, exploitation and utilization of local pig genetic resources in China. The contents and types of fatty acids in longissimus dorsi muscle were measured in Nanyang Black Pig and Big White Pig with 12 pigs per breed. Monounount saturated fatty acidn, polyunsaturated fatty acidn, saturated fatty acid saturated fatty acidn 12-16 carbon-saturated fatty acid, other saturated fatty acids (saturated fatty acid 2SFA2, unsaturated fatty acidsn UFA2 / SFA-1 / MUFAA), essential fatty acids Fatty acidae, conjugated linoleate linoleic acidsof CLAA, 蠅 -6PUFAA / 蠅 -3PUFA, etc. The fatty acid quality of two pig breeds was evaluated from nutrition, health, flavor and storage. The results showed that 30 kinds of fatty acids were detected in the longissimus dorsi muscle of two pig breeds, 23 of which had significant or extremely significant difference between the two pig species, except SFA2/SFA1 and 蠅 -6PUFAA / 蠅 -3PUFA. Other indexes of Nanyang black pig were higher than that of large white pig (SFA1 / MUFAA / UFAA / UFASFAS / UFASFA2 / SFA2 / MUFA1 / MUFAA / 蠅 -6 PUFAA / 蠅 -3PUFA). There was no significant or extremely significant difference in 11 indexes between the two breeds (P0.05, P0.01SFA2 and PUFA/MUFA). Combined with the above results, the muscle fatty acid quality of Nanyang black pig was superior to that of big white pig.
