Glazing process can improve the baked texture and overall quality of bread. In this study, the effects oftraditional glazes (water, oil, cheese powder, xanthan gum) on the physicochemical and sensoryparameters of sorghum gluten-free bread were compared with Lepidium sativum seed gum. wateractivity, moisture, firmness and sensory parameters of breads were evaluated. Results showed cheesepowder had the lowest moisture and vegetable oil treated samples had the lowest water activity.Evaluation of crumb firmness implicated water, Lepidium sativum seed gum diminished the breadstaling and these treated samples had the lowest firmness. Application of glazing ingredients did nothave any significant (P<۰.۰۵) effect on odor and taste. Lepidium sativum seed gum as a novel glazewas more effective than xanthan gum and its application was better than the usual glazes to improve thecrust and overall quality of gluten-free bread.
