ABSTRACT
The potent aroma compounds in butter from four kinds of Chinese butter hotpot seasoning were first investigated by analyzing the isolates from solid-phase microextraction. A total of 49 aroma compounds were identified, and 23 of them were highly correlated with the aroma profiles of the butter by partial least squares regression analysis. Aroma extract dilution analysis and odor activity value calculations were applied to further reveal the dominant odorants. Fifty-three odorants with flavor dilution factors between 1 and 1024 were identified and OAVs of 17 odorants were greater than 1. Finally, an aroma recombination experiment was prepared by mixing the aroma-active compounds (OAVs > 1), and the aroma profile of the recombination showed good agreement with that of the original sample. Omission tests showed that 2-furfurylthiol, 2-acetylthiazole, anethole, (E)-2-decenal, and 1,8-cineole were the key odorants for the overall aroma of butter.
