DEVELOPMENT OF A DNA BARCODE BASED METHOD FOR FOOD TRACEABILITY AND DETECTION OF ADULTERATION OR FRAUD FOR LIQUID GOODS

摘要

In this paper we present the development of a DNA barcode based method to rapidly identify the source of food and detect fraud or adulteration of liquid goods. The DNA barcodes are used to apply the product identification directly on or in the food products. We applied DNA markers and traced several food items through the supply chain to demonstrate both stability of the tracers as well as ability to correctly identify source when products of different origins are commingled. We also demonstrated the feasibility of using this method for detection of adulteration of olive oil.
