“…Methods of statistical evaluation have been used not only for the authenticity and traceability of food types but also to identify potential adulteration [11]. This study was undertaken to determine whether statistical analysis of elemental analysis could be used not only to determine the geographic growing regions of Jamaican versus foreign coffee, but also to differentiate various growing regions within the island such as Blue Mountain Coffee growing regions and High Mountain Supreme growing regions.…”

This study was undertaken to determine whether elemental analysis could distinguish the growing origins of Jamaican versus international coffee and identify intra-island growing regions. Twenty-four samples of roasted and ground coffee and soluble coffee were collected and analysed using instrumental neutron activation analysis and inductively coupled plasma optical emission spectroscopy. Sixteen elements were selected for statistical evaluation. Soluble clustered discretely from roasted and ground samples. The distinction among roasted and ground samples was not as discrete. Geographic growing regions could be determined by statistical analysis; separating the growing sub-regions in Jamaica would require additional analyses.
