The Dairy Industry Innovation Institute conducted independent market research aimed at verifying the accuracy of labeling on milk with a declared beta-casein A2A2 genotype. Eleven commercially available milk products were analyzed. The test results revealed significant discrepancies: in as many as 45% of samples, manufacturer claims were inconsistent with the actual facts, meaning that milk labeled as A2 also tested positive for the presence of the A1 variant. These results highlight the need for verification of products in this category available on the market.
