Formulated food inks for extrusion-based 3D printing of personalized foods: a mini review

3D food printing is an emerging technology to structure foods from digital designs. A number of inks are formulated 3D/4D print with customized appearance. This mini review focuses on the recent developments in personalized modified sensorial properties (e.g. texture and flavor). Varying sensory perceptions printed could lead eating behavior changes among consumers potentially achieve nutrition. Modifying geometric designs varying spatial distributions ingredients common techniques alter foods. The high degree customization indicates its potential as on-demand production tool for Nevertheless, we suggest that longitudinal consumer insights robust printers needed further
