Red beetroot colour was varied from 2% to 5% w/w of rice flour before extrusion and extruded under previously discussed conditions. After extrusion, the moisture content of the extrudates was below 7%. Rodríguez-Miranda et al.(2011)reported moisture content below 10% in extruded snacks to prevent its spoilage. Sensory evaluation using ten-member panel showed the sample extruded with 4% red beetroot colour to be most acceptable in terms of appearance, colour and overall acceptability, and hence was used for further experiments
