A1 and A2 Beta-Casein Testing

Beta-casein makes up about 30% of the protein in cows (bovine) milk.  In recent years, there has been growing interest in testing for A1 and A2 type beta-casein in milk and dairy products, and Analytica has testing methods that have been refined over a number of years.

Analytica’s testing is used by farmers and dairy manufacturers with an interest in producing milk or dairy products that meet particular specifications for beta-casein content.  It covers the following applications:

Farm testing

  • Identifying the genetic makeup of dairy cattle for beta-casein based on DNA testing, or analysis of the beta-casein in liquid milk samples from individual milking animals.
  • Measuring the amount of A1 type beta-casein in bulk milk, to monitor the milk being produced by a particular herd or group of animals.

Manufactured dairy product testing

  • Measuring the amount of A1 type beta-casein in manufactured milk products, milk powders, and other dairy products.
