Production and Quality Evaluation of Arabic Bread from Different Gluten-Free Flours

This study aims to produce gluten-free flatbread for Celiac Disease ( CD) patients from different gluten – free flour sources and compare its quality with that produced from wheat flour. Arabic flat pocket - former bread was prepared from the flours of wheat, corn, millet, buckwheat, quinoa, rice, potatoes, and tapioca using the straight dough method, and its physical quality parameters of specific volume, pocket formation, upper to lower layer ratio and water activity as well as sensory parameters of , freshness immediately and 4 hours after baking, and taste were evaluated.
Proximate composition of the flours indicated that wheat flour had the highest protein content followed by corn, millet, quinoa, and buckwheat while rice, potatoes, and tapioca flours had the lowest protein content. Sensory and physical evaluation of the bread types showed that most flour types gave bread loaves with good specific volumes compared to wheat flour. Most bread types were tender when freshly baked, but only wheat and potato breads maintained their tenderness 4 hours after baking. The taste of potato and tapioca breads were the most acceptable and similar to that of wheat bread ( P≤0.05). It can be concluded that pocket-forming flatbread with good sensory and functional characteristics can be produced from most flours if consumed fresh after baking.
