A comparison of DNA extraction methods for food analysis

In this paper, two DNA extraction and purification procedures for food analysis, Wizard (R) Magnetic DNA Purification for Food (Promega) and DNeasy (R) 'Tissue Kit (QIAGEN), have been compared concerning extraction efficiency, DNA purity and DNA suitability for amplification. The comparison of two extraction methods, in this study, has highlighted the efficiency of the Wizard (R) Magnetic DNA Purification approach for vegetable matrices while the revised DNeasy (R) Tissue Kit for complex and processed matrices.
