What are the characteristics of an powdered milk?

Powdered milk is characterized by its long shelf life, lightweight, and convenience for storage and transport. It retains the nutritional content of liquid milk, including proteins, vitamins, and minerals, but has reduced moisture content, which prevents spoilage. When reconstituted with water, it can be used similarly to fresh milk in cooking, baking, and beverages. Additionally, powdered milk is available in various forms, such as whole, skim, and non-fat, catering to different dietary preferences.
