How long should soybeans be soaked before processing?
It depends on the temperature of the soaking water and the ambient temperature. It can vary from 2 to 24 hours. Shorter the soaking time, more critical it is to use the beans quickly to prevent fermentation. Over soaked bean ferment and become sour. Soymilk yield is reduced dramatically, and in extreme cases, soymilk curdles even prior to extraction.
