中文摘要: 选取240 日龄朗德鹅、扬州鹅、浙东白鹅以及皖西白鹅各12 只,取胸肉进行食用品质、营养品质以及挥发性风味物质的测定。结果表明:4 种鹅肉的pH 值均在正常范围值内,肉色较好,皖西白鹅熟肉率最高,食用品质较好,浙东白鹅剪切力最低;4 种鹅肉的蛋白质、脂肪、水分和灰分含量差异均不显著(P>0.05);在4 种鹅肉中共检测出30 种脂肪酸,皖西白鹅脂肪酸含量最高,达到51.55 mg/100 g,对鹅肉风味的产生有重要作用,棕榈酸、硬脂酸、山嵛酸、油酸以及二十碳五烯酸是其主要脂肪酸(占比81.83%),多不饱和脂肪酸占饱和脂肪酸的比值(polyunsaturated fatty acids/saturated fatty acid,PUFA/SFA)为2.52;朗德鹅具有最低的动脉粥样硬化指数(atherogenic index,AI)值(0.23),其次是皖西白鹅。鹅鲜肉中共检测出17 种氨基酸,其中7 种为必需氨基酸,其中皖西白鹅具有最高的氨基酸含量(41.57 mg/100 g),鹅肉中必需氨基酸占总氨基酸的比例(essential amino acid/amino acids,EAA/TAA)达到33.12%,鲜味氨基酸含量达到0.96 mg/100 g;共鉴定得到17 种挥发性有机物,醛、酮和酸是鹅生肉的主要风味物质,其中皖西白鹅具有最丰富的挥发性物质类别,3-羟基-2-丁酮、丙酮以及4 种酸是皖西白鹅的风味主体;主成分分析结果表明长链不饱和脂肪酸和部分氨基酸(缬氨酸、亮氨酸、赖氨酸、酪氨酸和精氨酸)分别是皖西白鹅、扬州鹅区别于其他鹅种的主要标志,扬州鹅与浙东白鹅呈现较高的相似度。
Abstract:The edible quality,nutritional quality,and volatile flavor compounds of meat samples collected from 240-day-old geese of four breeds (Yangzhou geese,Zhedong geese,Wanxi geese,and Landes geese;12 geese were sampled for each breed)were measured.The results showed that the goose meat samples of all the four breeds had normal pH and good color.Wanxi geese had the highest cooked meat percentage,demonstrating the best quality,and Zhedong geese had the lowest shear force.The protein,fat,moisture,and ash content had little differences among the four goose breeds(P>0.05).A total of 30 fatty acids were detected in the goose meat samples of the four breeds,and the fatty acid content of Wanxi geese was the highest,reaching 51.55 mg/100 g.Palmitic acid,stearic acid,behenic acid,oleic acid,and eicosapentaenoic acid were the main fatty acids(81.83%)in the meat of Wanxi geees,and the polyunsaturated fatty acid/saturated fatty acid(PUFA/SFA)ratio reached 2.52.Landes geese had the lowest atherogenic index(0.23),followed by Wanxi geese.A total of 17 amino acids were detected in the goose meat,including 7 essential amino acids.Wanxi geese had the highest amino acid content (41.57 mg/100 g),the essential amino acid/total amino acid (EAA/TAA)proportion of 33.12%,and umami amino acid content of 0.96 mg/100 g.A total of 17 volatile organic compounds(VOCs)were identified.Aldehydes,ketones,and acids were the main VOCs of raw goose meat.Wanxi geese had the most abundant VOCs,which were dominated by 3-hydroxy-2-butanone,acetone,and four acids.The results of principal component analysis showed that long-chain unsaturated fatty acids and some amino acids(Val,Leu,Lys,Tyr,and Arg)were the markers distinguishing Wanxi geese and Yangzhou geese from other goose breeds,respectively.Yangzhou geese showed high similarity with Zhedong geese.
