DNA barcoding combats fake food

The substitution or mixing of higher value food and beverage ingredients with inferior or sub-standard products is an increasingly lucrative market, and of continued concern to the health of consumers. According to a study by Allied Market Research in 2015, the counterfeit food and beverage market is estimated to be reach US$62.5 billion globally by 2020. To counter this, researchers from Italy have developed a cheap and efficient technology, called NanoTracer, that uses DNA barcoding to not only identify the substitution of higher value ingredients, but also its dilution with cheaper ones.
