Homemade soy milk powder, or other plant-based milk powder

I have tried making soy milk powder from store bought soy milk. I used my dehydrator, but a few hours into the process the milk was starting to smell sour. I have seen recipes that make soy milk powder from the soybeans itself, but I have no access to soy beans.

Has anyone have had succes making soy milk powder this way? Is it possible to dehydrate store bought soy milk without it turning sour?

I am thinking of trying dehydrating almond milk next. The goal is to make an instant chai latte powder. I like my chai latte best with soy milk but am open to whatever plant-based milk will dehydrate properly.

Thanks!

You are going about the process the wrong way - the milk powder in this case is made of pulverized soy beans. Once you add water to this powder to make the milk, it will be very difficult, time consuming and expensive to dehydrate it to make the powder.

The reason your dehydrating milk is turning sour is either that it has picked up some bacteria or yeast from the air or contact with a slightly contaminated surface and these are growing happily in the nice warm dehydrator, similar to making yoghurt from milk. The other possibility is that there are some (bio)chemical changes going on with the heating which result in a sour taste. I would put my money on the bacteria/yeast option.

Your best bet will be to buy some dry soy beans, soak them to remove any dirt, then dry overnight, roast to denature proteins then pulverize them yourself. You can use a blender/spice grinder to do much of the work, but to get it fine enough to work well as milk, you might need to do a bit of manual labour with a mortar and pestle. There is a recipe here.
