This agricultural technology utilizes biodegradable, edible coatings made from sweetpotato pulp and peels, combined with essential oils and biopolymers, to preserve postharvest potatoes and sweetpotatoes. These coatings reduce skin greening and sprouting caused by light exposure, extending shelf life and improving food safety. By repurposing agricultural waste, the innovation supports sustainability and offers an eco-friendly alternative to synthetic preservatives. It addresses key postharvest challenges and opens market opportunities in produce preservation, sustainable packaging, and organic food supply chains.
