How long is the shelf life / Best before date of milk powder?
The shelf life of powdered milk in vending machines will depend on the type they contain. For example, skim milk powder contains 5% or less moisture and less than 1.5% milk fat, which makes it last longer than whole milk powder or buttermilk.
Therefore, if you are going to use powdered milk for vending, it is best to use skimmed milk. (and not only for its long lasting life, but for foam reasons, but this in yet another story to be told some when else)
Shelf life
Although different entities, such as the US Department of Agriculture (USDA), ensure that powdered milk lasts between 2 and 10 years, after the expiration date has passed, it is recommended that you follow the instructions from manufacturers. Laqtia granulated milk for vending machines, for instance, has an expiration date of 18 months.
How to store powdered milk for vending machines so that it is better preserved?
Maintaining the powdered milk in optimal conditions depends, on correct storage.
The transport and storage of milk powder for coffee machine must be done in a cool and dry place, at temperatures below 25º and with a relative humidity of less than 65%, therefore, it should not be put in the fridge.
Powdered milk should be in a hermetically sealed container, out of the light.
As it cannot contain moisture, a wet teaspoon should not be placed in the container, for example, as this could moisten the rest of the product and consequently spoil it.
When should I throw away the milk powder?
First of all, you must bear in mind that you must discard the milk powder from your vending machines when it passes its expiration date, but there are also some signs that can warn you that it is time to discard it.
If the powdered milk in your vending machines gives off a bad smell, it means that it is in poor condition. On the other hand, if some lumps have formed, it is because moisture has entered, and therefore, that milk can no longer be consumed.
Likewise, the appearance of mold on the surface is also an indicator of its poor condition. This is also due to the entry of moisture into the product, hence the importance of storing it well in an airtight and dry place.
