A gradual decrease in pH value was noted during storage. Increasing moisture levels caused a slight reduction in total protein content in the sample during storage.
There was no change in protein content during storage on dry matter basis.
These results are consistent with those reported by Furukava and Yamamanaka [16], in kulfi mix powder titratable acidity increased over a period of 8 months storage at 30 °C when packed in the different kinds of packaging materials.
