Key Points

Cooked is key: Raw soybean powder is unsafe to eat and must be cooked to deactivate anti-nutritional factors.

Check processing method: Differentiate between raw soy flour and roasted soybean powder (Kinako), which has already been cooked.

Is It Safe to Eat Soybean Powder?

Yes, you can eat soybean powder, but only if it has been properly cooked or processed. Raw soybeans contain anti-nutritional factors like anti-trypsin and thrombin, which can hinder digestion. Heating soybeans deactivates these compounds, making the powder safe. Many commercial soybean powders, such as kinako, are made from roasted soybeans and are safe to consume directly.
