摘要： Enzyme-modified butter (EMB) is well-known for its rich flavour, which is primarily defined by the process of enzymatic hydrolysis. This study employed lipidomics and flavouromics to assess the differences between EMBs and to uncover the intrinsic links between volatile organic compounds (VOCs) and lipids. Approximately 273 lipids and 82 VOCs were identified in butter. Palatase 20,000 L and Lipase MHA 10SD had the strongest hydrolytic activities, enhancing flavours characterised by the highest content of acids, followed by lactones and ketones. Combined with the variable importance in projection in partial least squares-discriminant analysis, 19 differential lipids and 41 key VOCs were identified. Further correlation analysis demonstrated that aldehydes were negatively correlated with unsaturated triglycerides, whereas ketones and lactones were negatively correlated with saturated triglycerides containing medium-chain saturated fatty acids. Interactions between lipids and VOCs offers theoretical insights that could inform the advancement of EMB technology.
