Influence of sweet almond protein concentrate and xanthan gum on physic-chemical and textural properties of dough and rice cakes

Cake, because of various tastes and ease of use, is the most important baking product after bread. Considering the mechanism of celiac disease, which develops because person's body cant digest the gluten proteins, producing gluten free cake is increasing across the world. The goal of this research is to analysis using of sweet almond protein concentrate (SAPC) in four levels ( 0, 5, 10, 15) and xanthan gum in three levels ( 0, 0.2, 0.4) (rice flour basis) on physical characteristics of dough and chemical and textural properties of free-gluten cake . Results show that by increasing the level of SAPC, protein, moisture, and ash of cake increase. By adding xanthan gum and SAPC, Special weight and Consistency of dough increase too. According to these results, the sample containing 0.4% xanthan and 15% SAPC has the most hardness and sample with 0.4 % xanthan and without SAPC has less hardness. Besides, xanthan decreases gumminess and increases springiness and cohesiveness. SAPC increases gumminess and decreases springiness and cohesiveness. Finally level of 2.0% for xanthan and 5% for SAPC due to suitable quality properties were accepted.
