Studies on Madhuca butyraceae seed proteins.

ABSTRACT

Defatted Madhuca butyraceae seeds contain 24% of crude protein and 10.4% of saponins. The solubility of Madhuca seed proteins was determined in water and NaCl as a function of pH and minimum solubility occurred at pH 4.0. The proteins consist of three components with S20,w values of 2.2, 9.8 and 15.4. On gel filtration the proteins gave three peaks and on diethylaminoethyl cellulose chromatography they resolved into two components. The in vitro digestibility of Madhuca seed protein was found to be 69% when assayed with a pepsin-pancreatin system.
