Abstract
We studied the changes of total dry matter and mois ture content, solubility, titrable acidity, acid degree value and scorched particle co ntent in whole milk powder (WMP) during storage of 18 months (shelf-life). Samples were stored at room te mperature and at maximum 15°C (maximum limit stipulated in Romanian standard). The samples were analyzed after obtaining and at 3, 6, 9, 12, 15 and 18 months intervals for the mentioned physico-chemical parameters. Values indicated an increase in titrab le acidity and moisture content with a decrease in tot al dry matter and acid degree value with the storag e time in whole milk powder. No significant changes were observed with solubility index under these conditions. Scorched particle content do not exceeded disc A in whole milk powder samples in neither of two differ ent storage conditions during shelf-life.
