dc.description.abstract | BACKGROUND: Tigernut is a typical foodstuff from a specific region of Valencia (Spain) called ‘L'Horta Nord’, where it is com- mercialized under a Protected Designation of Origin (PDO) as Chufa de Valencia (‘Valencia's tigernut’). PDO-recognized tiger- nuts present unique characteristics associated with their particular production region. Increasing demand and the associated expansion of its cultivation area has made necessary an exhaustive quality control to check the geographical origin and quality seal. RESULTS: In this work, a new multivariate analytical method capable of authenticating the PDO quality seal of tigernut samples was developed. Tigernut fat fraction was extracted under optimal conditions, applying the methodology of design of experi- ments. The analytical method combined fingerprinting methodology and chemometric tools to observe the natural grouping of samples using the exploratory analysis method and to develop classification models (partial least squares–discriminatory analysis; PLS-DA) to discriminate between two sample categories: (i) PDO tigernuts; and (ii) NON-PDO tigernuts. CONCLUSION: The built PLS-DA model demonstrated 100% accuracy, high sensitivity and specificity, revealing that the tigernut fat fraction can be applied to authenticate the PDO quality seal. | es_ES |
