Determination of the country of origin of garlic (Allium sativum) using trace metal profiling.
A method for determining the country of origin of garlic by comparing the trace metal profile of the sample to an authentic garlic database is presented. Protocols for sample preparation, high-resolution inductively coupled plasma mass spectrometry, and multivariate statistics are provided. The criteria used for making a country of origin prediction are also presented. Indications are that the method presented here may be used to determine the geographic origin of other agricultural products.
