Powdered milk shelf life10/9/2023 ![]() ![]() If you have access to a can sealer, #10 cans make wonderful storage containers for dry milk, particularly if used in conjunction with O2 absorbers.Īnother method I've seen used is to remove the paper envelopes of milk powder from the cardboard box they come from the grocery store in and to put them in dated plastic bags. Being glass, the jar can be reused as well as the lid and ring if they're properly cleaned.Ĭlean, sound plastic one and two liter soda bottles can also be used, but probably should be used just once since the plastic is somewhat permeable and will hold odors. An O2 absorber would take care of any remaining oxygen and would, itself, last longer when used in conjunction with the vacuum sealer. Larger jars of 1 gallon size could be used and then re-vacuum sealed after each use. Vacuum sealing and then storing in a dark place may be the best method. Since they are as transparent the contents must be protected against light. They must be guarded against breakage, but they offer the advantage of not holding odors, thus allowing for reuse after suitable cleaning. They are dated and stored in the ubiquitous cool, dark place. Once the jars are filled I add a small desiccant pack and seal. The method I now use is to pour the powder into clean, dry half-gallon canning jars. I've seen a number of methods used for this and any of them should work. I purchase the instant variety at my local grocery and repack it when I get it home. If the dry milk purchased was not packaged for long term storage then it should be repackaged right away. Vacuum canning or oxygen absorbers will also decrease the available oxygen. Powdered milk canned with nitrogen or carbon dioxide to replace air (which contains oxygen) will keep longer than powdered milk exposed to air. The use of desiccants is an excellent idea. The drier it can be kept, the better it will keep. ![]() If the storage container is transparent or translucent then it should be put into a second container opaque to light or stored in a dark room.ĭry milk will absorb moisture and odors from the air so storage containers should be impervious to both air and moisture. If it is possible to do so, air-conditioning or even refrigeration can greatly extend the nutrient shelf life. The area where your dry milk is stored should be kept as cool as possible. Their vitamins A and D are also photosensitive and will break down rapidly if exposed to light. How can you tell if powdered milk is bad or spoiled? The best way is to smell and look at the opened powdered milk: if the opened powdered milk develops an off odor, flavor or appearance, or if mold or insects appear, it should be discarded.Dry milk products are probably the most sensitive to environmental conditions storage foods there are, particularly to temperature and moisture content. The freezer time shown is for best quality only - powdered milk that has been kept constantly frozen at 0° F will keep safe indefinitely. How long does opened powdered milk last in the freezer? Properly stored, it will maintain best quality for about 3 years, but will remain safe beyond that time. Is powdered milk safe to use after the "expiration" date on the package? Yes, provided it is properly stored and the package is undamaged - commercially packaged powdered milk will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the powdered milk will remain at peak quality.Ĭan you keep opened powdered milk in the freezer? Yes, to further extend the shelf life of opened powdered milk, freeze it place the opened powdered milk inside covered airtight containers or heavy-duty freezer bags. How long does opened powdered milk last at room temperature? Properly stored, a package of opened powdered milk will generally stay at best quality for about 3 months at room temperature.
