Soy milk powder is soy milk from which all water has been removed, similar to cow's milk powder. Soy milk powder has a white to beige colour and mixes readily with warm or cold water. It can be made of plain soy milk or can contain additional ingredients, such as sugar, flavours and calcium. While it is not as common as cow's milk powder, soy milk powder can be found in some stores in the US. In Europe it is even more difficult to find, but can be easily ordered online.
