The solubility of tempeh solids in water reached 52%, and in 66% ethanol reached 28%, when followed during a 72-hr. fermentation period. The 66% ethanol-soluble components were mainly lipids, while the water-soluble components were rather evenly divided between crude protein, nitrogen-free extract (NFE), and lipids. At the end of the fermentation, two-thirds of the NFE and half the crude protein and fat had become water-soluble.
