In Italy, researchers in the Nutri3D project have unveiled prototypes of nutrient-rich sweet snacks made from cultured plant cells, fruit byproducts, and 3D printing. The creations include multi-layered snack bars and glossy “honey pearls,” designed to preserve flavor and nutritional value while offering a sustainable alternative to conventional treats.
The process involves growing plant cells from basil and Swiss chard in bioreactors, feeding them sugar, vitamins, and minerals instead of relying on soil or water. By combining these cultured cells with fruit residues from jam production, ENEA has turned waste into high-value food. “Developing innovative systems like plant cell agriculture and 3D printing is a strategic approach to producing sustainable, health-promoting foods,” Silvia Massa, scientific coordinator of the project, tells Green Queen.
The work is being carried out by ENEA, the country’s national research agency,
