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:
- 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.
