摘要

3D printing is used to manufacture novel food items. This study attempted the characterization of a food ink created from a composite paste of okra powder and raw jackfruit flour suitable for 3D printing. Okra powder was added to jackfruit powder at different concentrations (0–2%; w/w), and a paste was made by adding distilled water. For assessing the printability of food ink for desired 3D-printed products, several raw paste properties, such as rheology, gel strength, WHC, and microstructure, were evaluated. In addition, printing parameters such as powder concentration, nozzle height, diameter, extrusion rate, and nozzle speed movement were optimized. The standardized parameters for nozzle speed of 22 mm2 /s and extrusion rate of 0.003 m3/s, with a nozzle height to diameter ratio of 1:1.25, were set as the printing parameters to print the desired 3D structures with superior resolution, smoother texture, and without deformation.
