Ultrasound-assisted construction of pea protein isolate-folic acid covalent complex as self-assembled nanocarrier: Enhancing the stability, precise release property, and bioaccessibility of curcumin

Key Points

• Enhanced bioaccessibility of curcumin is achieved through a covalent complex with pea protein isolat e and folic acid.
• The complex shows a well-controlled release property, improving stability when compared to non-complexed curcumin under similar conditions.
• Ultrasound-assisted methods effectively facilitate the construction of this self-assembled nanocarrier, optimizing integration of biomolecules.
• This analysis highlights the potential for improved delivery systems in nutritional applications and therapeutic interventions.
