Key Points

The research aims to investigate how ultrasound and zinc ions affect the fibrillation of pea protein and its implications for delivering astaxanthin.
Examined the structural evolution of pea protein under ultrasound and zinc ions.
Analyzed hydrophobic interactions and disulfide bond formation during fibrillation.
Evaluated the antioxidant capacity, digestive stability, and bio-accessibility of astaxanthin.
Fibrils formed showed an antioxidant capacity of 38.19%, significantly higher than free astaxanthin's 9.37%.
Hydrophobic interactions were identified as the primary force for fibrillation.
Synergistic treatment improved protein stability and nutrient delivery.

Implication

Demonstrates enhanced astaxanthin delivery in pea protein using ultrasound and zinc ions, suggesting effective nutrient bio-enhancement.

Abstract

= 25,408.3), which made hydrophobic interactions the dominant driving force for fibrillation while suppressing disulfide bond formation. In addition, CO bond transformation and protein backbone reorganization were involved in fibril formation. Fibrils formed under synergistic treatment were found to further enhance the antioxidant capacity, digestive stability, and bio-accessibility of AST (38.19%), whereas the bio-accessibility of free AST was only 9.37%.
