Food Authenticity Testing to Protect Consumer Interests and Public Health
Authenticity testing is utilized to prove that the content of food products are authentic and the way they are presented is correct and accurate. Government regulations are in place to verify the authenticity and origins of a product, including those that are sourced internationally. Intentional adulteration or counterfeiting is considered food fraud and can result in billions in economic loss and long-term damage to brand reputation. It can also pose a serious threat to public health. Common testing for food fraud includes GMO screening and meat or fish species identification.
Air-dryable mix exhibits high specificity for detecting low level contaminants in complex food samples
Figure 3 . Detection of Bovine mitochondrial ATP Synthase DNA in extracts of beef meat (black), pork meat ( pink ) and pork meat contaminated with 0.4% beef ( red ) using air-dried Air-Dryable ™ qPCR Mix. The results illustrated specificity of the Air-Dryable ™ qPCR Mix, being able to distinguish the pork meat contaminating the beef product.
Figure 4 . A 10-fold serial dilution of Bovine mitochondrial ATP Synthase DNA was amplified over 4 orders of magnitude using the Air-Dryable ™ qPCR Mix. The results illustrated sensitivity and reproducibility of the Air-Dryable ™ qPCR Mix, being able to detection down to 1 genome equivalent ( blue ) with very good correlation coefficient and reaction efficiency.
