Minority compounds and sensory analysis evaluation of Coffea arabica var. caturra cultivated in three different altitudinal ranges

The composition of minority compounds in samples of roasted and ground coffee ( Coffea arabica var. caturra) cultivated in three altitudinal ranges 1300-1400, 1400-1600, 1600-1800 m. a. s. l., in the Huila department of Colombia were determined. The samples were collected in July of 2012. pH, total acidity and total lipids were measured. Subsequently, the composition of total lipids after esterification and gas chromatography analysis coupled to high resolution mass spectrometry (GC-MS) was established. Quality cup test considering the following attributes:  fragrance/aroma, taste, residual flavor, acidity, body, uniformity, balance, clean cup, sweetness, quality and note, were performed. No statistically significant difference (p 0.05) was found in the evaluated attributes at the quality cup test at different altitudinal range.
