主 题:adulteration coffee chromatographic methods carbohydrates volatile substances
摘 要:Coffee is currently the second largest commodity on the world market today,and there is great concern about the quality of the beans exported from producer countries to Europe and *** such as using blends of different species and adding low-cost raw materials,such as chicory,corn,and soybean,impair the sensory and functional characteristics of the drink made from roasted and ground coffee *** is a need to adopt more efficient analytical methods than the microscopy technique currently *** first chromatographic method used to determine fraud was reported in *** method used paper chromatography to differentiate between coffee and chicory based on the free reducing *** of the 1980s,different methods involving high-performance liquid chromatography and gas chromatography were developed in order to demonstrate geographic authenticity,distinction between species,occurrence of adulteration,and the presence of defective beans by determining the monosaccharides,oligosaccharides,tocopherols,fatty acids,volatiles,diterpenes,sterols,and phenolic substances,among *** far as the authors know,there are no papers published in the literature that have compiled such an extensive set of information about these chromatographic methods as *** the last 2 years,there has been a trend to develop analytical methods for ultra-performance liquid chromatography coupled with tandem mass spectrometry to confirm fraud in coffee,due to high sensitivity and selectivity.
