ChemistrySelect, Volume 11, Issue 26, 10 July 2026.Molecular modeling reveals how ZIF‐8 captures 17β‐estradiol and 17α‐ethinylestradiol through noncovalent interactions. DFT, NCI, and QTAIM analyses provide mechanistic insights into adsorption and support the potential application of ZIF‐8 for endocrine‐disruptor removal from water.

Impact of Grape Seed Extract on Flavor and Functionality of Pea Protein Extrudates and Patties
Journal of Food Science, Volume 91, Issue 7, July 2026.ABSTRACT Consumer interest in plant‐based proteins is increasing, but undesirable off‐flavors from Maillard reaction and lipid oxidation processes hinder their broader acceptance. Our previous work showed that proanthocyanidin‐rich plant extracts like grape seed extract (GSE) could reduce the formation of these off‐flavors in aqueous plant protein ...
