The Effect of High-Pressure Processing on the Copigmentation and Storage Stability of Polyphenols with Anthocyanin Monomers.

ABSTRACT: This study aims to determine the effect of different high-pressure processing (HPP) conditions (100 MPa/300 MPa/500 MPa; 2 min/4 min/6 min) on copigmentation, specifically between chlorogenic acid (CA), epicatechin (Epi), gallic acid (GA), malvidin-3-O-galactoside (Mv-3-O-gal), and malvidin-3-O-arabinoside (Mv-3-O-ara), as well as the storage stability of the copigmentation solutions. The results showed that the influence of different HPP treatment conditions on copigmentation was not significant. HPP treatment did not significantly affect the λ_max, peak absorption, color parameters, and Mv-3-O-gal anthocyanin content when applied alone or in combination with CA and Epi. However, the color intensity and a* value of Mv-3-O-gal with GA decreased by 3.2% (p < 0.05). T
