Exploring the feasibility of multi-element fingerprinting with chemometrics for discriminating the geographical origins of asparagus and its risk assessment.

Abstract

This study explored the efficacy of multielement analysis combined with element fingerprints and chemometrics to discriminate the geographical origins of asparagus (Asparagus officinalis L.). It investigated the potential health hazards of long-term intake of asparagus. 19 elements were set as variables, and the geographical origin discrimination analysis was conducted through element fingerprints and chemometrics. The principal component analysis (PCA) provided no clear regional delineations, w
