Abstract

Symbol of hospitality, coffee is the second beverage most consumed in Brazil and its regular and moderate consumption brigs several benefits to human health. In the year of 2015 were exported over 33 million coffee bags generating revenues of almost US$ 5.6 million to Brazil which is the largest producer and exporter of this commodity. The oil extract from raw coffee bean has an elevate potential to pharmaceutical and cosmetic industries, due to its cicatrizing properties and the presence of compounds that block UV rays action. Given high commercial value to coffee and by-products, furthermore it is pertinent to concern about possible adulterants added to the product in order to cheapen costs, like corn, soybean, coffee husks or even wood pieces. Until this moment, was find no methodologies that were embracing and robust to determinate and quantify adulterants presence in coffee samples; and relative to the coffee oil there is no reports in literature about adulterants analysis. A great alternative to determinate the contaminants is NMR technique, which shows itself very promising in analysis of other food matrixes. To analyze the coffee oil another technique very promising in gas chromatography, because through triacylglycerols and free fatty acids composition can be identified the presence of adulterants.
