Quality characteristics of gluten free cookies prepared from different flour combinations.

Abstract

The present investigation was undertaken on the utilization of alternate flours/meals (rice (Oryza sativa), maize (Zea mays), sorghum (Sorghum vulgare) and pearl millet (Pennisetum glaucum) for the preparation of gluten free cookies as compared to conventional wheat (Triticum aestivum) flour cookies. The physicochemical parameters, sensory qualities and functional properties of flours/cookies were studied and compared with control cookies. The blend of maize and pearl millet had best pasting qualities followed by blend of pearl millet and sorghum flour. The control cookies showed a higher yield (186.8%) but stronger peak force (2.69kg). The cookies prepared from rice and maize combination had highest spread ratio whereas, the lowest spread ratio was observed in rice and sorghum combination. The cookies with pearl millet and sorghum flour combination had higher fat, protein, ash and calorific values as compared to control cookies. The maximum sensory overall acceptability scores were found for cookies prepared from combination of pearl millet and sorghum flour followed by rice and sorghum, maize and sorghum, rice and maize, maize and pearl millet, rice and pearl millet and control cookies. All gluten free cookies had higher nutritional value as compared to control cookies and were acceptable by panelists.
