Coffee Origin Determination Based on Analytical and Nondestructive Approaches –A Systematic Literature Review

Abstract

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.

Metabolomics: A suitable foodomics approach to the geographical origin traceability of Ethiopian Arabica specialty coffees

“…High‐quality single‐origin coffee producers may use misleading labels, false declarations, and fraudulent practices to increase their economic profit. The Swiss Federal Food Safety and Veterinary Office recently reported a falsely declared “100% Arabica” coffee that was substituted with the less expensive robusta coffee (Aurum et al, 2022; Federal Food Safety and Veterinary Office, 2019). Due to the fact that coffee quality is linked to specific growing areas, incorrect geographical indications are also illegal.…”

“…Due to the fact that coffee quality is linked to specific growing areas, incorrect geographical indications are also illegal. In response to modern consumer demands for coffee origin authenticity, various strategies encompassing a wide range of technology and scientific techniques have been implemented to ensure (Aurum et al, 2022; Klikarová & Česlová, 2022).…”

Teknologi Artisan Coffee Roasting Pada Pengusaha Café Probolinggo Dalam Upaya Menghasilkan Kopi Lokal Berkualitas

“…Sementara itu, Kopi Toraja dari Sulawesi dikenal dengan citarasa buah dan rempah yang kompleks, sementara Kopi Mandheling dari Sumatera memiliki kekentalan yang khas dan aroma yang kaya. Setiap daerah memiliki varietas kopi yang unik, seperti kopi Arabika dan Robusta, yang membentuk karakter rasa yang berbeda-beda [11]. Faktor iklim, tinggi tempat, dan tanah yang berbeda menghasilkan varietas yang berkembang dengan karakteristik tertentu.…”

Identifying the origin of Yemeni green coffee beans using near infrared spectroscopy: a promising tool for traceability and sustainability

“…Currently, a few methods are used to identify the geographical origin of green coffee beans, including chemical analysis, such as isotope fingerprinting, Nuclear Magnetic Resonance (NMR) and, more recently, Near Infrared Spectroscopy (NIRS) 20 , 27 – 30 . These approaches can be used alone or in combination to determine the origin of green coffee samples and, by extension, to avoid fraud.…”
