WebThe extent of pH decline also affects water holding capac-ity. Water is a dipolar molecule that is most likely to bind to proteins that have a net charge. Meat proteins have no net charge at pH 5.1. This point is referred to as the isoelectric point. As the pH of meat approaches that low pH of 5.1, the water holding capacity drops drastically. WebpH is the Key Factor in Relation to Meat Quality and Animal Welfare The pH of a living muscle at rest is 7.2 to 7.4, but in se- vere physical and mental stress, lactic acid is produced, pH may temporarily decrease to 6.2.
