不同处理方式对花椒提取液及卤鸭脖挥发性风味成分的影响

为探究不同处理方式对花椒挥发性风味成分及其赋予酱卤鸭脖挥发性风味物质能力的影响,分析了粉碎水提、未粉碎水提、粉碎醇提、未粉碎醇提、粉碎汤提和未粉碎汤提处理对花椒卤水及卤鸭脖肉中风味物质组份的影响。采用气相色谱-质谱联用(GC-MS)及气相色谱-离子迁移谱(GC-IMS)技术分别测定不同处理方式下的卤水及卤制鸭脖中主要挥发性风味成分差异。GC-MS结果表明,花椒卤水主要呈香化合物为醇、烃、酯和醚类,水提可提高花椒卤水中4-萜品油醇等醇类物质的溶出,醇提可提高毕澄茄烯等物质溶出,汤提对醚类物质的溶出效果较好,粉碎处理能有效促进烃、酯类物质的溶出,不利于醇、醚类挥发性成分在卤水中保留。不同处理方式下,经花椒提取液卤制后鸭脖肉中的主要物质均为4-萜品油醇、桉叶油醇;水提能显著促进桉叶油醇、柠檬烯对卤鸭脖的赋香,醇提使茴香脑的赋香效果较佳,花椒是否经过粉碎处理对于所制得的卤水赋予鸭脖肉挥发性风味物质没有显著影响。基于GC-IMS谱图分析,发现对于提取液而言,水提和汤提的粉碎处理无明显差异,醇提相较于水提、汤提具有明显差异;在卤鸭脖中,是否粉碎处理对花椒挥发性风味物质的呈香无明显差异;醇提相较于水...

Effects of Different Processing Methods on Volatile Flavor Components of Zanthoxylum bungeanum Maxim. Extract and Braised Duck Neck

To investigate the effects of crushed water extraction, uncrushed water extraction, crushed alcohol extraction, uncrushed alcohol extraction, pulverized soup post-extraction and unpulverized soup extraction on volatile flavor components of Zanthoxylum bungeanum Maxim. and its ability to confer volatile flavor substances to braised duck neck was studied. Gas chromatography-mass spectrometry (GC-MS) and gas chromatography-ion mobility spectrometry (GC-IMS) were used to determine the differences of main volatile flavor components in brine and braised duck neck under different treatment methods. GC-MS results showed that the main aromatic compounds in Zanthoxylum bungeanum Maxim. were alcohols, hydrocarbons, esters and ethers. Water extraction could improve the dissolution of 4-terpineol and other alcohols, and alcohol extraction could improve the dissolution of pyoletene and other substances. Decoction extraction had a better dissolution effect on ethers, and crushing treatment could effectively promote the dissolution of hydrocarbons and esters, and was not conducive to the retention of volatile components of alcohol and ether in the brine. The main substances in braised duck neck were 4-terpenoid and cineole after brine preparation of Zanthoxylum bungeanum Maxim. extract under different treatment methods. Water extraction could significantly promote the retention of eucalyptol and limonene in braised duck neck. Ethanol extraction improved the effect of anethole in duck neck. Whether Zanthoxylum bungeanum Maxim. was crushed or not had no significant effect on the volatile flavor substances assigned to duck neck by the prepared brine. Based on GC-IMS spectrum analysis, it was found that for the extract, only alcohol extraction showed significant differences. Similarly, only alcohol extraction showed significant difference in braised duck neck. The volatile flavour compounds of different treatments for Zanthoxylum bungeanum Maxim. extract and gives braised duck neck ability has a significant effect of volatile flavor substances.
