Introduction:
Chlorophyll (Chl), a natural photosynthetic pigment, is limited in large-scale applications by costly organic solvent extraction and poor stability under light and heat.
Methods:
This study explores an electric induction method to promote Chl aggregation, forming stable aggregates that protect and extract Chl. By controlling induction time, aggregates of varying sizes and quantities are generated.
Results:
Quantum chemical calculations on Chl derivatives show that electric induction causes Chl molecules to move toward the positive electrode, forming aggregates that exhibit J-type-like characteristics through intermolecular charge transfer (CT). Chlorophyll self-aggregation markedly enhanced the thermal stability of Chl. The findings indicated that the highest retention rate was observed in the 30 min group, which improved by 78.43% compared to the control group.
Discussion:
This efficient extraction method preserves Chl's structure, enhances its thermal stability, and reduces organic solvent use, providing a sustainable approach for Chl extraction and protection.
