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. In living animals, the ac- cumulation of lactic acid causes pain and distress (Gregory, 1998). 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 – A measure of how acidic or basic a solution is. A pH of 1.0 indicates a highly acidic solution while a pH of 14 indicates a highly basic solution. A pH of 7.0 indicates a neutral solution Normal, living resting muscle typically has a pH of approximately 7.2. The pH of meat can range from about 5.2 to 7.0. bird perched on light bulb
