Coaxial extrusion-based printing for designing foods having personalized properties – Presented by Valerie Vancauwenberghe, PhD, Post-Doc, KU Leuven, MeBioS division, Belgium, on June 28, at the 3D Food Printing Conference, during the Agri-Food Innovation Event 2018 at Brightlands Campus, Villa Flora, Venlo, The Netherlands.
Low methoxylated pectin gel is a promising food-ink for the 3D printing of healthy candy having variable textural and structural properties. However, the actual printing method based on simple extrusion requires an incubation post-treatment in calcium solution in order to complete the gelation of printed objects. Coaxial printing can avoid the need of post-treatment by accurately controlling the gelation of printed pectin objects through the simultaneous deposition of pectin ink and crosslink solution.
Coaxial extrusion-based printing can be applied for more food products than pectin gels and thus, could innovate and bring more possibilities in the personalization of printed foods.
