How Long Does Powdered Milk (Nonfat) Last in Mylar Bags?
Quick Answer: Nonfat powdered milk lasts 15-20 years in mylar bags with oxygen absorbers and desiccant. Whole milk powder only lasts 2-5 years due to fat content. Use 300cc absorbers per gallon. Desiccant is essential as powdered milk absorbs moisture rapidly.
