This work aims at investigating the impact of commonly used sweeteners- sugar and jaggery on 3D printability of rice flour (RF) paste. The physico-chemical characteristics of rice flour suitable for 3D food printing have been investigated. Three mixes, rice flour with water (M1 : RF- 50.86 %, Water- 49.14 %), rice flour with sugar and water (M2 : RF- 36.75 %, sugar- 14.10 %, Water-49.14 %) and rice flour with jaggery and water (M3 : RF- 36.75 %, Jaggery- 14.10 %, Water-49.14 %) were compared on 3D printability based on visual inspection and properties supporting 3D printability and shape retention. The effect of the three mixes were characterised on colour, rheological, thixotropic and handling properties. Out of the three mixes M3 is found to have the best printability characteristics with shear thinning behaviour, yield stress of 157 Pa, flow stress of 121 Pa and extrusion force of 6.62 kg.
