Analysis of copigmentation between organic acids and cyanidin 3-<i>O</i>-glucoside in blackberry wine.

ABSTRACT:

Background

Cyanidin 3-O-glucoside (C3G) is the most abundant anthocyanin in nature. However, the copigmentation of organic acids with C3G has not been analyzed. In this study, the contents of organic acids and C3G in blackberry wine were determined, and the copigmentation between them was investigated.

Results

The addition of organic acids did not significantly change the molecular weight of the compounds in the solution. Regarding the copigmentation of organic acids with C3G, the organic acids altered the solution polarity. This led to the rotation of the B ₋ ring plane of C3G, restored the shielding color intensity, and enhanced the color rendering strength of the C3G solution. Hydrophobic and hydrogen bonding forces are the main intermolecular forces that affect th
