Freeze Drying Dairy Products

Dairy can be freeze dried, but results vary by fat content. Lower-fat dairy items generally perform better. Milk, yogurt, and some cheeses can freeze dry successfully. Liquids should be poured in thin layers so they freeze quickly and dry evenly. High-fat dairy products are harder. Butter and heavy cream contain lots of fat and relatively little water, so they do not dry well and may not store as long. Packaging matters. Dried dairy absorbs moisture quickly. Seal promptly in jars or high-quality bags and store cool and dry.
