Powdered hibiscus anthocyanin‐nanofibril complexes as natural colourants: Stability and application in yoghurt and soft candy

Coloration Technology, EarlyView.
Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...
