Turning Your Non-fat Powdered|
Milk Into 1%, 2% Or Whole Milk
The powdered milk we sell is non-fat milk, or skim milk and only offer this type because of it’s long storing qualities. If your family pretty much refuses to drink skim milk, there is a relatively easy way to add some fat back into your milk giving it a much closer taste to whole milk. Or, if you like, you can make 1% or 2% milk. Here is how you do it.
The Concept: Emulsify some vegetable oil then add it to your reconstituted milk. The word ‘emulsify’ means 'to suspend small globules of one liquid into a second liquid with which the first will not mix.' Two examples of this are the fat in regular milk and using soap to dissolve grease. In both cases, fat is broken up into millions of microscopic particles which are prevented from coming back together again by the emulsifying agent. (To get a better idea of how this works, see our Chemistry in Soap Making page.) Eggs are one of the best known food-safe emulsifying agents. In fact, mayonnaise is nothing more than a lot of oil and a very little bit of egg and vinegar that have been emulsified together. We are going to do the same thing. Caution should be taken not to use fresh, raw eggs because of the fear of Salmonella. Use powdered eggs instead. The manufacturers claim powdered eggs are Salmonella-free.

In a gravy shaker add milk then egg powder. Shake until well dissolved. Add vegetable oil and shake vigorously for 1 to 2 minutes. Your oil should now be in a fine emulsification. Add this to your ‘Amount Milk Desired’ and shake briefly.
Your oil will stay in suspension for a long time. However, much like cream in raw, unhomegenized milk, over time the fats in the milk will float to the top. The oil will be cream colored, though, and still emulsified with the egg. A quick shake of your milk jug will mix them back up for several hours.
I chose a gravy shaker in these instructions making this possible without electricity. However, under normal conditions, a blender will create a much finer emulsion. Mixed in a gravy shaker, it took about 2 hours for the emulsified fat to raise to the top of the container. It took 6-8 hours for the much more finely emulsified fat to rise in the container that had been processed in a blender. You will have better luck mixing the larger batches than smaller batches. This is because the egg powder and oil won't be so diluted in the milk, permitting the emulsion process to work better.
If you'd like to re-fat your powdered milk with real butterfat, you could also add a small amount of sweet cream to your reconstituted milk and shake it vigorously or quickly blend it. Over time, you can decrease the amount of fat you put in your milk and gradually wean them off the richer milk.
