Is it necessary to soak soybeans before processing?
No. However, soymilk extraction is better when soybeans are soaked for hydration. Traditional beany processes use soaked soybeans. Older non-beany soymilk processes grind dehulled dry soybeans without soaking in alkaline hot water to control beany flavor. The most modern method uses soaked soybeans and controls beany flavor problem by preventing oxidation. Also, modern soaking methods minimize flatulence-causing oligosaccharides.
