A convenient and robust protocol for preparation of ODAP-free Lathyrus sativus protein

The present study aimed to develop a protocol for easy removal of β-ODAP neurotoxin by converting it into its isomer α-ODAP (reported to be less toxic) followed by its separation from the protein fraction in pH dependent manner. Use of β-mercaptoethanol prevented aggregate formation and increased solubility of the prepared Lathyrus sativus protein. Validation of ODAP removal by paper chromatography and mass spectrometry indicated the robustness of the protocol. Removal of ODAP and presence of high antioxidants and homoarginine content can enable Lathyrus sativus to be an alternate source of protein, as well as have other health benefits, including benefits for patients with cardiovascular diseases.
