“…Minor and trace elements account for only 5 % by mass in coffee [19] but nonetheless, the elemental concentrations and research has shown that the elemental signatures carry over from year to year [20], further bolstering the case for use of elemental analysis as a tool for determination of geographic origin. In the case of Jamaican Blue Mountain coffee a combination of characteristics are deemed responsible for its international reputation; the altitude at which it is grown, temperature variations, duration of growth and the soil [16].…”

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.

“…Isotope dilution mass spectrometry, using inductively coupled plasma mass spectrometry (ICP‐MS), has been applied to discriminate coffees from different regions of Hawaii . In addition, elemental and isotopic compositions, determined using inductively coupled plasma optical emission spectrometry (ICP‐OES) and ICP‐MS, have been used to establish the provenance of green coffees from various countries and continents . Phenolic profiles obtained using ultra‐performance liquid chromatography with quadrupole time‐of‐flight mass spectrometry (UPLC‐qTOF‐MS), alkaloid compositions determined using high‐performance liquid chromatography coupled to a diode array detector, and elemental contents obtained using ICP‐OES, have been used to characterize the production region of green coffee beans from Ethiopia.…”

BACKGROUND This study was aimed at the development of objective analytical method capable of verifying the production region of the coffee beans. One hundred samples of green coffee (Coffea arabica L.) beans from the major producing regions, comprising various sub‐regional types, were studied for variations in their fatty acid compositions by using gas chromatography coupled with mass spectrometry. Principal component analysis (PCA) was used to visualize data trends. Linear discriminant analysis (LDA) was used to construct classification models. RESULTS Twenty‐one different fatty acids were detected in all of the samples. The total fatty acid content varied from 83 to 204 g kg−1 across the regions. Oleic, linoleic, palmitic, stearic and arachidic acids were identified as the most discriminating compounds among the production regions. The recognition and prediction abilities of the LDA model for classification at regional level were 95% and 92%, respectively, and 92% and 85%, respectively, at sub‐regional level. CONCLUSION Fatty acids contain adequate information for use as descriptors of the cultivation region of coffee beans. Chemometric methods based on fatty acid composition can be used to detect fraudulently labeled coffees, with regard to the production region. These can benefit the coffee production market by providing consumers with products of the expected quality. © 2019 Society of Chemical Industry

“…For instance, Atomic Absorption Spectroscopy (AAS) was used by Grembecka et al [3] to determine concentrations of 14 elements, and used them to differentiate the types of coffee (ground, instant) using multivariate statistics. Valentin and Watling [4] employed Inductively Coupled Plasma spectroscopies (ICP) to determine the provenance of coffee samples from 15 countries, based on the contents of 59 elements. Antoine et al [5], with measurements through Neutron Activation Analysis (NAA) and other methods, determined the origin of ground coffee consumed in Jamaica.…”

Coffee is becoming one of the most popular beverages in Mexico. In the present work, X-ray Fluorescence (XRF) was used to determine the contents of several elements (with atomic numbers between 11 and 38) in 11 samples of commercial ground coffee, comparing with another one of soluble coffee and two of used ground coffee. Samples were dried at room temperature and pelletized. XRF analyses were carried out using a spectrometer based on an Rh X-ray tube, registering the characteristic x-rays with a Silicon Drift Detector. The system detection calibration and accuracy check was performed through the analysis of NIST certified reference materials 1547 (peach leaves), 1570a (spinach leaves), 1573a (tomato leaves), and 1571 (orchid leaves). As a general rule, the elemental concentrations measured are similar in all samples of coffee, in values not exceeding toxic levels. However, the differences among the elemental concentrations are shown.
