摘　　要：文章比较研究了杂种黑猪(长白山野猪×莱芜猪×杜洛克猪)和外三元杂种猪(杜洛克猪×长白猪×大约克猪)的肉质性状,测定了肉色、大理石纹、p H24、嫩度、保水性(失水率、汁液损失、贮藏损失、蒸煮损失和熟肉率)、肌纤维直径、肌内脂肪含量、肌苷酸含量、游离氨基酸含量、脂肪酸(棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸)含量和挥发性物质成分等指标。结果表明,杂种黑猪肉的L*值、a*值、熟肉率、游离氨基酸含量和油酸含量显著高于外三元杂种猪肉(P<0.05);外三元杂种猪肉的失水率、汁液损失显著高于杂种黑猪肉(P<0.05);杂种黑猪肉的p H24极显著高于外三元杂种猪肉(P<0.01);杂种黑猪肉的亚油酸含量极显著低于外三元杂种猪肉(P<0.01);大理石纹、嫩度、贮藏损失、肌纤维直径、肌内脂肪含量、肌苷酸含量、棕榈酸、硬脂酸、亚麻酸和挥发性物质成分等指标,二者无明显差异(P>0.05)。因此,杂种黑猪的肉质优于外三元杂种猪,可满足人们对高品质猪肉的需求。Meat quality of crossbreed black pigs（Changbai mountainxLaiwuxDuroc） and DLY pigs（Duroc×Landrace×Yorkshire） was comparatively studied.Meat color,marbling,pH^tenderness,water holding capacity（pressure loss rate,drip loss,storage loss,cooking loss and cooked meat rate）,muscle fiber diameter,intramuscular fat content, inosinic acid content,free amino acids contents,fatty acids content（palmitic acid,stearic acid,oleic acid,linoleic acid and linolenic acid）,and volatile components were determined.The results showed that,the L＊,a＊,cooked meat rate, free amino acids contents and oleic acid content of crossbreed black pigs were significantly higher than that of DLY pigs（P〈0.05）;the pressure loss rate and drip loss of DLY pigs was significantly higher than that of crossbreed black pigs（P〈0.05）;the pH24 of crossbreed black pigs was higher than that of DLY pigs（P〈0.01）;linoleic acid content of crossbreed black pigs was lower than that of DLY pigs（P〈0.01）;there were not significant difference in marbling,tenderness,storage loss,muscle fiber diameter,intramuscular fat content,palmitic acid content,stearic acid content,oleic acid content and volatile components （P〉0.05）.Therefore,the crossbreed black pigs in term of meat quality characteristics were better than DLY pigs,and could meet the needs of people for high quality meat.
