Because fresh food spoils quickly, many packaging and preservation innovations have helped to extend transportation hardiness and shelf life. Now, a new bioresin made from tomato plant byproducts could make it safer to eat ubiquitous canned goods.
Led by the Stazione Sperimentale per l’Industria delle Conserve Alimentari (Experimental Station for the Food Preserving Industry), in Parma, Italy, the BIOCOPAC (biocopac.eu/en) consortium is developing a bio-based thermosetting lacquer. Most metal food packaging has a BPA-filled liner or chemical-based lacquer to prevent corrosion. While these keep the can intact, they have been linked to deleterious effects on the food inside.
