CSIRO printed foods! Focus on highly nutritious foods: - High protein - Smaller serves with a high nutrient loading - Use of novel ingredients Fun shapes for kids Full of vitamins & fibre A gecko printed from: (above) β -carotene & butter (above) beetroot powder & chickpea IMAGES: Courtesy of Filip Janakievski, (left): carrot powder CSIRO Agriculture & Food & starch 9 | 3D printing for personalised nutrition | Stephen Homer
Does structure affect digestion? Currently working on various protein gel structures Investigating their rates and extent of digestion Uses in vitro techniques for gastric and intestinal stages 10 | 3D printing for personalised nutrition | Stephen Homer
What might the future look like? One printer to print many types of foods using different “trigger mechanisms” Temperature control (heating and cooling) Multi-channel extrusion Extrusion of different material types Consideration of microbiological safety • Ingredient storage • Cleaning Could this be the next food revolution? 11 | 3D printing for personalised nutrition | Stephen Homer
