Guest guest Posted February 18, 2009 Report Share Posted February 18, 2009 The white foam or froth from soaking beans comes from the activation of natural yeast, like sourdough yeast, that are on the outside surface of the beans. When you first start to cook the beans in water, the yeast get especially active because of heat, and make a lot of foam (carbon dioxide) before the heat gets too high and the yeast are killed. In baking bread the same thing causes oven-spring to give a big boost to a well-made loaf.
