“3D printing candy with desired texture according to personal dietary requirements using pectin gel” – Presented by Valérie Vancauwenberghe, KU Leuven

Pectin is a complex and structurally diverse group of polymers widely used in jelly, jam or low-calorie products. This study demonstrated that low methoxylated (LM) pectin gel is a suitable material for 3-D printing. Moreover, variable properties can be obtained by varying the gel formulation such as pectin or sugar syrup concentrations. Air bubbles can also be trapped and stabilized with surfactant protein in order to provide particular porosity which may provide subtle texture properties. This promising edible ink would give the opportunity to future customers to design in 3-D their candy with desired texture according to their personal dietary requirements.
