pH and Acidity in Food Science: Safety, Quality, Processing, and Shelf Life Control
pH and Acidity in Food Science: Difference, Food Safety, Titratable Acidity, Fermentation and Shelf Life Control In food science, pH and acidity are not just laboratory terms. They are core control points that affect food safety, flavor, texture, fermentation, preservation, processing behavior and shelf life. A food technologist, quality officer, food safety inspector, dairy analyst, beverage processor or student cannot fully understand food quality without understanding these two concepts. Many people use pH and acidity as if they mean the same thing. This is a common mistake. They are related, but they are not identical. pH tells how active the acidity is. Titratable acidity tells how much total acid is present. This difference is very important in food analysis. A product may have a low pH, but its total acid content may not be very high. Another product may have the same pH but a stronger sour taste because it contains more total acid. This is why both pH and titratable acidi...
