Bioaccessibility of anthocyanins and bioactive compounds from Brazilian berries and their food matrix interaction: an in vitro gastrointestinal digestion study coupled to UHPLC‐ESI‐TQD‐MS/MS analysis

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Several commercial berries have been examined for anthocyanin composition, bioaccessibility, and bioactive effects, while Brazilian berries remain underexplored. This study aimed to access the effect of in vitro gastrointestinal digestion on anthocyanin bioaccessibility, stability, and antioxidant potential in black pitanga (Eugenia

Regenerative Polyphenolic Free‐Standing Conductive Film

Macromolecular Materials and Engineering, EarlyView.
A rare combination of self‐assembly, spontaneous regeneration, and free‐standing form is achieved from initially non‐conductive polyphenol–amine complexes. The resulting films, assembled at the air/water interface and carbonized in one step, demonstrate flexibility, conductivity, and scalability.

Bio‐Based Epoxy Resins from Estragole: Achieving High Glass Transition Temperatures Comparable to DGEBA and Simultaneously Low Viscosities

Macromolecular Materials and Engineering, EarlyView.
Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins
