The present study was carried out to develop gluten free cereal bars for gluten intolerant population. The cereal bar was formulated using dry raw materials (quinoa, brown rice, flaxseed and dry fruits) and binding agents (honey). Honey was added as a sweetener and binding agent. The raw materials were assessed for physico-chemical parameters such as moisture, ash, crude protein and fat content and the functional parameters such as antioxidant activity, total phenolic content and β-carotene. Dry heat treatment (80–100 °C for 8–12 min) was given to grains (quinoa, brown rice and flaxseed) prior to use in preparation of cereal bar. Significant variation was found after treatment of grains among all the physico-chemical and functional parameters of grains except ash content which showed a non-significant variation. Four formulations (F1, F2, F3 and F4) were developed using different combination of grains at different honey levels (40, 50 and 60%). On the basis of sensory evaluation, formulation- 4 at 50% honey level was found to be best. Selected cereal bar was assessed for physico-chemical and functional parameters. Selected cereal bar had 8.53% moisture content, 1.34% ash content, 10.50% protein content, 2.89% fat content, 0.51 mg GAE/g total phenolic content, 33.87% antioxidant activity and 0.384 µg/g β-carotene.
