Studies of the technological and sensory properties of gluten-free bread Affected by using novel edible surface coating and traditional glazes

Glazing process can improve the baked texture and overall quality of bread. In this study, the effects of traditional glazes (water, oil, cheese powder, xanthan gum) on the physicochemical and sensory parameters of sorghum gluten-free bread were compared with Lepidium sativum seed gum. water activity, moisture, firmness and sensory parameters of breads were evaluated. Results showed cheese powder 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 bread staling and these treated samples had the lowest firmness. Application of glazing ingredients did not have any significant (P<۰.۰۵) effect on odor and taste. Lepidium sativum seed gum as a novel glaze was more effective than xanthan gum and its application was better than the usual glazes to improve the crust and overall quality of gluten-free bread.
