However, these ratios should be used with caution, because the degradation products of compounds may vary with time in the atmosphere14. Nitro-PAHs are formed directly from combustion processes such as those in diesel and gasoline engines, as well as by oxidants in the atmosphere through both ...
The concentration of PAH compounds ranged from 38.3 ng·g−1 to 1782.5 ng·g−1 (dry weight, dw), with an average concentration of 542.2 ng·g−1 dw (Nap was excluded). Table 3 presents the summary of the detection ranges of the individual PAHs. In total, the detection ratios of...
This study aims to reveal the evolution mechanism of odour and taste active compounds in cooked marinated pork knuckles via typical process steps; among them, the brine soup stage was the most important part due to spices’ enriching flavours. These resu
Sugars and esters formed by fatty alcohol differ significantly between the assessed Chinese baijiu and Western liquors, and are potential marker compounds that could be used for their discrimination. Factors contributing to the differences in chemical composition are proposed. Our results improve our ...
