Innovative hydrocolloid-based edible coatings for food preservation
Oregon State University is developing natural, water-resistant, and antimicrobial edible coatings using hydrocolloids like cellulose nanofibers and chitosan. These coatings extend shelf life, reduce spoilage, and enhance food safety for various fresh produce and perishable foods, with ongoing development and promising applications in sustainable food packaging.
Overview
Oregon State University is advancing edible coating technologies utilizing natural hydrocolloids such as cellulose nanofibers and chitosan. These coatings are designed to be water-resistant, antimicrobial, and edible, addressing key challenges in food preservation like spoilage, water loss, and microbial contamination. The coatings are particularly suitable for fresh produce, meat, cheese, and other perishable foods, with the potential to significantly extend shelf life and reduce food waste.
