Fatty acid composition of three coffee blends was studied before and a
fter the roasting at 200 degrees C. This treatment produced a slight d
ecrease of saturated fatty acids and a slight increase of the unsatura
ted ones. The analyses were carried out by GLC. The discriminant analy
ses of the obtained results showed a clear separation between the raw
and roasted blends, and among two blends (Costaria and Colombia) compa
red to the third (Santos).
