Descripción

Application

• Stearic acid esterified pectin: Preparation, characterization, and application in edible hydrophobic pectin/chitosan composite films.: This research presents a novel method for esterifying pectin with stearic anhydride to create hydrophobic composite films. These films exhibit enhanced barrier properties and potential applications in food packaging, offering a biodegradable alternative to conventional materials (Wang et al., 2021).
