WebJun 7, 2024 · Titratable acidity is a better predictor of acid’s impact on flavor than pH. However, total acidity does not give all relevant information on a food. For instance, the ability of a microorganism to grow in a specific food is more dependent on the concentration of free hydronium ions, H 3 O +, than titratable acidity. WebThe results demonstrated that citric acid additions lowered the pH value (3.89 vs. 4.06) and induced a 20.03% reduction in ammonia-N content, a 341.95% increase in acetic acid production and a 24.09% increase in water-soluble carbohydrate content during the anaerobic period.
