Title

Quality assesment of green coffee imported to poland

Abstract

Green coffee Coffea canephora var. robusta from Indonesia, Vietnam, Uganda, Laos and Peru was analyzed directly after sampling from ships’ holds. Coffee from Vietnam was of the lowest quality, and contained 12.84% of water and 20.5% of defective beans on average, and was non-uniformly coloured. Coffee originating from Indonesia and Peru was of average quality and contained respectively 11.23% and 11.60% of water and 1.70% and 1.66% of insect-damaged beans, and also 7.48% and 5.65% of defective beans. The material from Uganda and Laos was of moderately good quality and contained respectively 12.34% and 12.36% of water. It also contained the smallest quantity of defective beans: 3.04% in coffee from Laos and 4.44% in coffee from Uganda. Additionally, the smallest quantity of insect-damaged beans was detected in coffee from Laos – 0.01%, but it contained ca. 4.5% of contaminants of plant and mineral origin (sand).
