Ionic calcium variation in normal, acidic, alkaline and unstable non‐acidic bovine milks and its relationship with alcohol stability.

Investigating the impact of ionic calcium (iCa) on alcohol stability and its correlation with suggested milk classification, a study analysed 379 bulk milk samples collected over 4 months. Results unveiled a significant inverse relationship between iCa concentration and alcohol test stability. Alkaline or unstable non‐acidic milk exhibited no disparity in iCa content compared to normal or acidic milks. Despite fluctuations in iCa levels, seasonal variations, not milk classification, better accounted for the changes in stable milk detection in the alcohol test at the 76% setpoint. The seasonal fluctuation in iCa within bulk tank‐collected milk carries implications for standardising industrial processes. [ABSTRACT FROM AUTHOR]
