Powdered skim milk has a shelf life of up to 18 months, whereas liquid milk expires after 18 days. Powdered milk is produced by expelling the liquid in regular milk, but it dehydrates without losing the majority of its nutrients.
Vitamins
A serving of powdered skim milk contains 10 percent of the Recommended Daily Allowance of vitamin A, which boosts the immune system, and 2 percent of the RDA of vitamin C, which is good for bone health and aids in the skin's healing processes.
