Published in 2021 at "Dyes and Pigments"

DOI: 10.1016/j.dyepig.2021.109438

Abstract: Abstract The fact that many copigments such as cinnamic acids exhibit an acid-base equilibrium at moderately acidic pH values have not been taken in consideration in the copigmentation models and respective equations. In this work,… read more here.

DOI: 10.1016/j.foodchem.2022.132518

Abstract: Copigmentation effects of aspartic acid, proline and valine on individual anthocyanins in strawberry juice (SJ) were investigated during heating at 90, 105 and 150 °C. Aspartic acid increased (4.5-45.6%) total anthocyanin stability at all temperatures, while… read more here.

DOI: 10.1016/j.foodres.2017.09.034

Abstract: In the recent research, the copigmentations of malvidin-3-O-glucoside with eight types of phenolic copigments have been investigated. The influence of the pigment/copigment molar ratio, the reaction temperature, the pH and the ethanol content of solutions… read more here.

Published in 2022 at "Journal of agricultural and food chemistry"

DOI: 10.1021/acs.jafc.2c03879

Abstract: Stopped flow corroborated by UV-vis measurements allowed for the calculation of the copigmentation constants of delphinidin 3-O-glucoside with the neutral (CP) and negatively charged CP(-) forms of chlorogenic acid. Solutions of delphinidin 3-O-glucoside in the… read more here.

Published in 2022 at "Journal of food science"

DOI: 10.1111/1750-3841.16269

Abstract: Anthocyanins in processed fruit degrade significantly due to their heat and oxygen sensitivity and water solubility. Copigmentation for stabilizing anthocyanins is less effective for whole fruit due to anthocyanins' location within cell vacuoles surrounded by… read more here.

Published in 2020 at "International Journal of Food Science and Technology"

DOI: 10.1111/ijfs.14409

Abstract: Pomegranate juices (PJs) were clarified using hydrocolloids [albumin (A), casein (C), chitosan (CH) and xanthan gum (XG)] and in combination with each other. The lowest turbidity was observed in PJs clarified with ‘CH+XG’ and ‘A+C+CH’.… read more here.
