摘 要:为探究不同国产虾酱中脂肪酸组成与挥发性风味成分差异,采用气相色谱、电子鼻以及固相微萃取-气相色谱质谱联用法对9种不同产地虾酱的脂肪酸组成以及挥发性物质进行检测。结果表明,虾酱中共检测出30种脂肪酸,添加香辛料与米酒的虾酱以多不饱和脂肪酸为主(53.310%~69.144%),添加了大豆油的虾酱以单不饱和脂肪酸为主(48.891%),未添加香辛料的虾酱中以饱和脂肪酸为主(55.173%~72.252%)。电子鼻可以明显区分添加米酒的虾酱与其他虾酱(P<0.05),但对其他几种虾酱区分不显著(P>0.05)。虾酱中共检测出243种挥发性风味物质,以醇类、醛类、酮类、芳香族化合物、酯类、吡嗪类为主。添加米酒的虾酱以酯类及芳香族化合物为主,添加大豆油的虾酱以酯类、吡嗪类、芳香族化合物为主,添加香辛料的虾酱中含有一定量的酰胺。产自广东的虾酱挥发性物质种类最为丰富,检测出80种以上挥发性物质。研究结果可为国产虾酱的产地溯源提供借鉴。To investigate the differences in fatty acid composition and volatile components in different domestic shrimp sauces,9 different types of shrimp sauce from different origins were selected to detect the fatty acid composition and volatile substances through gas chromatography,electronic nose,and solid-phase microextraction gas chromatography-mass spectrometry.Results showed that a total of 30 fatty acids were detected in shrimp sauce.The fatty acids in shrimp sauce added with spices or rice wine were mainly polyunsaturated fatty acids(53.310%-69.144%).The fatty acids in shrimp sauce added with soybean oil were mainly monounsaturated fatty acids(48.891%).The fatty acids in shrimp sauce without adding spices were mainly saturated fatty acids,ranging from 55.173%to 72.252%.The electronic nose could clearly distinguish shrimp sauce added with rice wine from other types of shrimp sauce(P<0.05),but it was not significant for distinguishing other shrimp sauces(P>0.05).A total of 243 volatile compounds were found in shrimp sauces,mainly alcohols,aldehydes,ketones,aromatic compounds,esters,and pyrazines.The flavor substances in shrimp sauce added with rice wine were mainly esters and aromatic compounds,while those in shrimp sauce added with soybean oil were mainly esters,pyrazines,and aromatic compounds.The volatile substances in shrimp sauce added with spices contained a certain amount of amides.The types of volatile substances in shrimp sauce produced in Guangdong were the most abundant(≥80)among the above domestic shrimp sauces.The research results can provide a reference for the traceability of domestic shrimp sauce.
