Influence of the β-Casein Genotype of Cow’s Milk (A1, A2) on the Quality and β-Casomorphin-7 (BCM-7) Content of a Semi-Hard Cheese During Production

Foods
Cow’s milk contains A1- and A2-β-caseins. The breakdown of A1-β-casein produces β-casomorphin-7 (BCM-7), a peptide with opioid-like properties that is associated with health aspects.

Determination of A1 and A2 β-casein in cow milk by high-performance liquid chromatography tandem mass spectrometry

Journal of Dairy Science
: A2 β-CN milk has gained widespread acceptance due to its nutritional benefits. To verify the authenticity and detect adulteration and contamination in A2 milk, we developed an HPLC-MS/MS method for determining the characteristic peptides of A1 and A2 β-

A2 milk - Advantages and Challenges in the Manufacturing of Dairy Products

Scientific Papers Animal Science and Biotechnologies
A2 milk is characterized by a difference in the amino acid at position 67 of the β-casein polypeptide chain, which releases much smaller amounts of bioactive opioid peptide β-casomorphin - 7 upon digestion.

Gene and Genotype Frequencies of β-Casein A1 and A2 in Different Dairy Cattle Breeds in Uberlândia, Minas Gerais

β-casein is a major protein in bovine milk and exists in two predominant genetic variants: A1 and A2. During the digestion of A1 β-casein, β-casomorphin-7 is released—a peptide associated with gastrointestinal discomfort and other potential adverse ...
