Development of a Microsphere-Based Immunoassay Authenticating A2 Milk and Species Purity in the Milk Production Chain. [PDF]
Molecules, 2022 Processed milk and milk products produced from bovine milk, commonly contain β-casein A1 (βCA1) and β-casein A2 (βCA2). Since the presence of βCA1 is linked to milk intolerance and digestion problems, A2A2 milk, which only contains βCA2, is proposed as a healthier alternative.

Development of a new sandwich ELISA for the detection of bovine A1 beta-casein. [PDF]
PLoS ONEThe bovine genetic variant A2 beta-casein is associated with fewer digestive and absorption issues compared to A1 beta-casein, leading to increased global demand for A2 milk.

Differential Release of β-Casomorphins from A1 and A2 Milk During Standardized Gastrointestinal Digestion Quantified by CE–MS [PDF]
Foodsβ-Casein A1 and A2 (β-CN-A1 and β-CN-A2) are the two predominant β-CN proteoforms in bovine milk. β-CN-A1 has been associated with a greater propensity to release opioid peptides, such as β-casomorphin-7 (β-CM-7) and β-casomorphin-5 (β-CM-5), during ...

Effects of β-casein A1/A2 milk and β- and κ-casein genotypes on the performance, body composition, and fecal score of dairy calves [PDF]
Scientific ReportsThe perceived health benefits of β-casein (β-CN) A2 milk for humans have driven increased selection for homozygous β-CN A2 dairy cattle. However, little is known about the effects of feeding milk with different β-CN variants to calves, or about the ...

A1- and A2-Milk and Their Effect on Human Health
Journal of Food Engineering and Technology, 2020 Milk proteins are a heterogeneous group of polymeric compounds that have a wide range of different molecular structures and properties. They occur as caseins, whey proteins, enzymes, minor proteins and nitrogen compounds. Caseins constitute about 80% of the total proteins of cow’s milk. β-casein is an important part of the caseins, which makes up about

The Characteristics of A1-A2 β-Caseins in Milk and Their Effects on Human Health
Turkish Journal of Agriculture: Food Science and Technology, 2021 Despite positive effects on nutrition, it has been reported that milk causes allergic reactions and many health problems. Allergic reaction to milk is called lactose intolerance, but it is estimated that this is not caused by lactose, but by the β ...

The Effect of A2 Milk on Gastrointestinal Symptoms in Comparison to A1/A2 Milk: A Single-center, Randomized, Double-blind, Cross-over Study. [PDF]
J Cancer Prevβ-Casein, a major protein in cow's milk, is divided into the A1 and A2 type variants. Digestion of A1 β-casein yields the peptide β-casomorphin-7 which could cause gastrointestinal (GI) discomfort but A2 milk containing only A2 β-casein might be more beneficial than A1/A2 (regular) milk.
