Can natural pigments in different emulgel phases stabilize each other against UV radiation? Anthocyanin and β-carotene co-loaded in an emulgel based on soy protein isolate-gellan gum conjugates.

Despite poor stability of natural pigments against degradation, using these colorants have attracted great interest due to their various beneficial effect on human health. Accordingly, in the present study, an emulgel based on soy protein isolate-gellan gum conjugate was fabricated via Millard reaction. Then, the effectiveness of emulgel on improving the stability of anthocyanin (ACN) and β-carotene (BC) with different loading concentration (5, 10, and 15 mg/mL) against UV-C irradiation was investigated.
