How is soy milk made?
Soy milk (soya drink) is made by soaking soybeans, blending them with water and straining the mixture to separate the liquid from the solids, according to the British Heart Foundation. Some brands use soy protein isolate instead of whole beans, and many add calcium and vitamin B12.

How is soy milk made?
The British Heart Foundation (BHF), a UK health charity, describes soya milk as produced by soaking soybeans and blending them with water, then straining the mixture. The liquid is pressed through a filter to separate it from the solids.
What is soy milk made out of?
- Soybeans, or in some brands soy protein isolate, which BHF describes as a concentrated extract in powder form.
- Water.
- Depending on the brand, stabilisers, emulsifiers, salt, oil, sugars or sweeteners.
Check the ingredient list on the pack, because it differs between brands.
Why is calcium added?
BHF says soya milk does not naturally contain calcium, so calcium is added, along with vitamin B12. Its table lists an unsweetened soya drink with 120 mg calcium and 0.3 micrograms vitamin B12 per 100 ml, both added. This is one example product type, not every brand.
What we could not confirm
We found no government or university page we could open that describes industrial steps such as the heating temperature. We therefore do not state cooking times or temperatures. For the choice between soy and cow milk for a child or a medical diet, ask a doctor or dietitian.
