In recent years, in order to meet the health needs of different people and create novel and interesting personalized selling points, food 3D printing has gradually gone from concept to implementation, such as 3D printing pizza and some novel baking solutions. Now, Barcelona researcher Giuseppe Scionti and his team have developed a plant-based steak production method using 3D printing technology.
While Scionti's "steaks" are made entirely of plant ingredients, they have the texture of beef. While not quite as aesthetically pleasing, the researchers claim it has an authentic taste and texture. The method is similar to many food 3D printing techniques, in which the paste is deposited into a steak and 100 grams of meat can be made in 30 to 50 minutes. The paste is made from Scionti harvested from rice or peas.
"The main difficulty is reorganizing the nanofibers from plant proteins to make them look like animal proteins," Scionti explains. "first, you have to study the histology of animal tissue and the way muscle fibers are organized, and then you have to try to replicate using unmodified plant ingredients."
It currently costs 2 euros to 3D print 100 grams of the meat substitute. Scionti expects prices to fall further as production increases. It could provide a viable alternative to the many failures of the agricultural industry. In addition, this method can be produced on demand to prevent food waste.
