A frequent question that I have heard is"What is the difference between Instant Powdered Milk and Non-Fat Powdered Milk?"  They are definately are not the same.

Instant Nonfat Powdered milk:

• Easy to mix with a spoon or blender as it dissolves more easily
• Chill overnight for best flavor for drinking
• May take twice as many granuals as powder to make Instant milk versus Non-fat Powdered Milk.
• It has a more "puffy" appearance

Regular Powdered Milk:

• More difficult to mix than instant milk
• Mix with hot water (or use the method I described a few posts ago)
• Blend in blender or with a wire whip
• Refrigerate until well chilled before drinking.
• Has a more "fine" and "powder" appearance.

Another frequently asked question is "What is a milk Alternative?"

• Blend of Grade A Sweet Dairy Whey, and Dairy Solids, and nondairy solids. 
• It essentially is not made directly from milk. 
• It is good for Lactose-intolerant individuals
• It may not work well in baking.
