【摘要】 本研究测定了甘南去势牦牛肉的挥发性风味物质,为其开发利用提供理论依据。以甘南去势牦牛为试验组、公牦牛为对照组,宰后均取背最长肌作为试验材料,测定其挥发性风味物质。甘南去势牦牛肉中共检测到48种挥发性化合物,包括16种醇、10种烃、6种醛、4种酸、5种酯、4种酮、芳香族2种及杂环类1种,醇类物质相对含量最高,约为38.02%,烃类物质为16.58%,醛类物质相对含量约为14.80%,酮类、酯类及酸类的相对含量分别为9.68%、6.72%和3.92%。公牦牛肉中共检测到50种挥发性化合物,包括16种醇、10种烃、6种醛、4种酸、5种酯、4种酮、芳香族3种及杂环类2种,醇类物质相对含量最高,约为37.78%,烃类物质为16.99%,醛类物质相对含量约为14.63%,酮类、酯类及酸类的相对含量分别为9.81%、5.85%和3.95%。甘南去势牦牛中的挥发性物质种类比公牦牛少两种,主要的呈味物质代表鲜香味的醛类物质、清香味的醇类及油香的酮类物质均高于普通公牦牛。更多还原

【Abstract】 In this study,the volatile flavor compounds of Gannan-castrated yak meat were determined in order to provide a theoretical basis for its development and utilization.There were 48 kinds of volatile compounds detected in Gannan Castrated Yak Beef,including 16 alcohols,10 hydrocarbons,6 aldehydes,4 acids,5 esters,4 ketones,2 aromatics,and 1 heterocycle.The relative content of alcohols was the highest,which was approximately 38.02%,hydrocarbons was 16.58%,the relative content of aldehydes was approximately 14.80%,and the relative contents of ketones,esters and acids were 9.68%,6.72%,and 3.92%,respectively..The Chinese Communist Party detected 50 kinds of volatile compounds,including 16 alcohols,10 hydrocarbons,6 aldehydes,4 acids,5 esters,4 ketones,3 aromatics and 2 heterocycles,and alcohols.The relative content of the substance is the highest,which is approximately 37.78%,the hydrocarbons are 16.99%,the relative content of aldehydes is approximately 14.63%,and the relative contents of ketones,esters,and acids are 9.81%,5.85%,and 3.95%,respectively.There are two types of volatile substances in Gannan castrated yaks compared with male calves,and the main flavoring substances represent fresh flavor aldehydes,clear scented alcohols,and oily ketones that are higher than ordinary male yak.更多还原
