    Characterization of physical, structural and antioxidant properties of hemp seed and seed meal protein-gallic acid conjugates by Wannawarang Tanbamrung, Suphat Phongthai, Pornchai rachtanapun, Kongsak Boonyapranai, Prem Thongchai, Liang Zhang, Kanyasiri Rakariyatham

    Published 2025-06-01
    “…This study investigated the effects of covalent modification of hemp protein isolates (HPIs) from seed and seed meal under alkaline reaction with gallic acid (GA) on physical, structural and antioxidant properties. By increasing the amount of GA (0 – 1000 μmol) during the conjugation process to form HPI-GA conjugates (HPI-GA0–1000), the binding between HPIs and GA were increased as total phenolic content of seed HPI-GA (sHPI-GA) conjugate significantly increased from 1.43 – 21.43 μg GAE/mg sample, although the binding efficacy of seed meal HPI-GA (smHPI-GA) conjugate was not as high. …”
