What is A2 milk?
Category : Uncategorized
A2 milk is cow’s milk that mostly lacks a form of β-casein proteins called A1 and instead has mostly the A2 form. Milk like this was brought to market by The a2 Milk Company and is sold mostly in Australia, New Zealand, China, United States and the United Kingdom.
A1 and A2 beta-casein are genetic variants of the beta-casein milk protein that differ by one amino acid. The A1 beta-casein type is the most common type found in cow’s milk in Europe (excluding France), the USA, Australia and New Zealand. A genetic test, developed by the a2 Milk Company, determines whether a cow produces A2 or A1 type protein in its milk. The test allows the company to certify milk producers as producing milk that does not metabolise to β-casomorphin 7.
