Pasta, chocolate, sugar: 3D printing in the realm of food is shaking up the culinary world and is delighting the taste buds of forward-looking gourmets. A team of researchers from the Luiz de Queiroz College of Agriculture at São Paulo University, Nantes Atlantic College of Veterinary Medicine, Food Science and Engineering in France and the French National Institute for Research on Agriculture, Food and Environment, have gone even further by developing modified starch hydrogels to use as “Ink” for making 3D printed food. ADVERTISEMENT. Tastier and more tailored foods. While it was already possible to use 3D printing to create food products that responded to consumer expectations of taste, texture, cost and nutrition, this research can lead to the elaboration of new shapes, textures, colors and flavors considered healthy and appealing for broader demographics, in particular children and the elderly. FEATURED STORIES. TECHNOLOGY. TECHNOLOGY. TECHNOLOGY. Several years and as many methods were needed to develop this new “Ink.” Two of their latest approaches – involving dry heating of cassava and wheat starch in an oven while controlling both temperature and time – have resulted in modified starch-based gels with “Optimal printability,” with a structure that is perfectly preserved after printing. The research team also added that these gels based on modified cassava and wheat starch could be used beyond the food sector. From now on, the team of engineers will focus on new materials and new methods to design more tailor-made ingredients and continue to revolutionize 3D printing applied to food and beyond.
