Food fraud presents complex challenges due to the diverse and intricate nature of food matrices and the numerous methods by which adulteration can occur. Historically, such complexity suggested the necessity of equally sophisticated analytical approaches. However, recent advances in the standardization and automation of Nuclear Magnetic Resonance (NMR) spectroscopy have transformed this comprehensive technique into an accessible tool, even for non-experts. Leveraging its quantitative capabilities, NMR combined with database-driven statistical analyses effectively verifies food authenticity, including critical factors such as geographical origin and botanical variety, thereby directly impacting product valuation and quality assurance. This presentation highlights specific instances illustrating the efficacy of NMR in combating food fraud. Notably, we discuss the detection of adulterated honey containing foreign sugars and the identification of mislabeled wines. These case studies underscore NMR's critical role in safeguarding food integrity and maintaining consumer trust.
