WebFree fatty acid,ketone contents and induction time and complete oxidation time were measured as the results of hydrolytic, ketonic and oxidative rancidity, respectively. Rancidity odor of the first 2 types was very repulsive and dependent on the concentration of free fatty acid and ketone. The odor of the oxidative one was mild.

WebIn-container sterilization of milk at 115 °C causes the pH to decrease to ~6 but much of this is due to the precipitation of calcium phosphate; the contribution of acids derived from lactose has not been quantified accurately. Other commercial heat treatments, including UHT sterilization, cause insignificant degradation of lactose to acids.
