This review paper aims to synthesize the current applications of rapid and simple chemical analysis methods for the geographical classification of edible nuts. Techniques such as Inductively Coupled Plasma (ICP), spectrophotometry, and mass spectrometry have been widely employed to differentiate nut origins based on their unique chemical signatures. Recent years have witnessed a significant increase in the number of studies using these methods, reflecting growing scientific interest in food authentication and traceability. By summarizing key findings and highlighting commonly used techniques, this review provides a comprehensive overview of the field and identifies promising directions for future research in the classification and origin verification of edible nuts.
