Juice obtained from alfalfa or other leafy green crops is processed to isolate a cream-colored protein fraction which is soluble, odorless, bland (essentially tasteless) and useful for human nutrition. The juice is first treated to remove chloroplastic proteins, chlorophyll, carotenoids, and lipids. The residual juice containing the desired cytoplasmic proteins is treated by novel procedures-e.g., acid precipitation in the cold or by membrane filtration followed by acid precipitation at ambient temperature-to isolate the soluble bland protein. |
