Extrusion parameters for nutritious expanded food with jaggery were optimized following box-benken design using Response Surface Methodology. Jaggery and feed moisture affected physical properties, while nutritional and sensory properties of products were influenced by jaggery only. Optimized level of extrusion parameters consisted of 100 oC die head temperature, screw speed 304 rpm, 14% moisture and 4g jaggery per 100g of formulation with 80% maize, 14% defatted soy-meal, and 6% sesame-based formulation having overall desirability of 0.807. This expanded food showed expansion ratio of 3.57, 173.76 kg.m-3 bulk density, 15.18% protein with 72.55% invitro protein digestibility and 2.63 protein efficiency ratio, 1.97% total minerals, 2.9 mg.100 g-1 iron, 158 mg.100 g-1 calcium with acceptability score of 8.2 that also indicated the consumer acceptability ?7 by 95.37% using 9-point hedonic scale. |
