“…Furthermore, harvest year and degree of ripeness were nonsignificant [35]. Another study employing ICP-optical emission spectrometry (OES) found that metal element content could discriminate the coffee origin from different countries in South America [36], the inter-Mexican region [37], cross-continental samples [38], Ethiopian coffee from 11 different regions [39] and different postharvest process [40], and Jamaican coffee against non-Jamaican [41]. In agreement with Valentin and Watling [35], Habte et al [39] confirmed that harvest year did not significantly influence coffee's elemental compounds.…”

Coffee attracts consumers worldwide for its unique sensorial properties. Its unique flavor is affected by numerous factors. The biochemical properties associated with geographical features are among the essential aspects that may modulate coffee's distinct sensorial profiles, and may be employed for its origin determination and authentication. This systematic literature review served to assess the newest techniques for coffee authentication, origin determination, and adulteration detection from analytical and nondestructive approaches. This study focused on the last 10 years' high-quality research in the field. Accordingly, 78 articles using both analytical and nondestructive methods for the determination of coffee origin and fraud detection were found in leading journal databases. Apart from the compound profile and instrumentation, data analyses including statistics, machine learning, and multivariate models which have been commonly used are discussed as well. In addition, other important information, such as data validation methods and the predictive capability of the above techniques are also reflected in this review.

“…However, their precise representation and quantity depend on many variables, such as the genotype of the coffee tree and its growing conditions (defined by the soil, climate, altitude, and other factors), post-harvest processing methods, the degree of the green coffee beans roasting, storage and distribution conditions, as well as coffee brewing methods [ 13 , 20 , 21 , 24 , 44 , 47 , 60 , 61 , 62 ]. Many studies have already been published in which elements [ 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 ], triglycerides [ 72 ], tocopherols [ 62 , 72 , 73 , 74 ], trigonellines [ 18 , 75 , 76 , 77 , 78 , 79 ], diterpenes [ 80 , 81 , 82 ], carbohydrates [ 76 , 83 , 84 , 85 , 86 , 87 ], polyphenols [ 36 , 37 , 39 , 65 , 75 , 76 , 77 , 78 , 88 , 89 , 90 , …”

Coffee is a very popular beverage worldwide. However, its composition and characteristics are affected by a number of factors, such as geographical and botanical origin, harvesting and roasting conditions, and brewing method used. As coffee consumption rises, the demands on its high quality and authenticity naturally grows as well. Unfortunately, at the same time, various tricks of coffee adulteration occur more frequently, with the intention of quick economic profit. Many analytical methods have already been developed to verify the coffee authenticity, in which the high-performance liquid chromatography (HPLC) plays a crucial role, especially thanks to its high selectivity and sensitivity. Thus, this review summarizes the results of targeted and non-targeted HPLC analysis of coffee-based products over the last 10 years as an effective tool for determining coffee composition, which can help to reveal potential forgeries and non-compliance with good manufacturing practice, and subsequently protects consumers from buying overpriced low-quality product. The advantages and drawbacks of the targeted analysis are specified and contrasted with those of the non-targeted HPLC fingerprints, which simply consider the chemical profile of the sample, regardless of the determination of individual compounds present.

“…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. Debastiani et al [6] analyzed Brazilian coffee samples with Particle Induced X-ray Emission (PIXE).…”

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.
