4. Rapid identification of A1 and A2 milk based on the combination of mid-infrared spectroscopy and chemometrics.

The milk containing only A2 β-casein (called A2 milk) is globally popular because of its unique health benefits. Traditionally, genetic testing (such as gene sequencing) is used to identify the cows with A2 β-casein gene that can only produce A2 milk, which is a time-consuming and costly method....
