Vacuum drying the resulting hot-air drying overcome solute separated phenomenon. Hot air drying the material to be dried so that the surface of the interior and large temperature gradients, prompting the dried material was distributed out some ingredients. Especially food, the aroma will be lost, affecting its taste. Vacuum dried material inside and outside temperature gradient is small. By reverse osmosis water as a solvent such that movement alone, to overcome the phenomenon of solute loss.
