Yes, that is not a problem.
I bring big bags of protein powder that I mix with water on the airplane to make a protein shake. I travel about 5 times a year and it's never been a problem.
yes you can because its a powder not a liquid
you get the milk powder and you mix it with the water (hot or cold) your choice
This depends of many factors: temperature, stirring, geometry of container, volume of water, mass of milk, agglomeration of milk powder.
the powder milk.
Most powdered milk is dehydrated skim milk.
Milk powder softens the crumb achieved in breadmaking. You will end up with a softer croissant by using milk or milk powder, as opposed to water. (Milk and milk powder give a very similar result).
Approximately thirty grams of milk powder will give you half a ltr of milk
SMP - Skimmed milk powder WMP - Whole milk powder
Yes. Heat and moisture can damage milk powder.
If it is unopened and you have the receipt, the store should take it back.
No, you have to use milk powder.
some whole milk is powder but most whole milk is preservative :D
