Preparation and Quality Evaluation of Gluten-Free Biscuits

The aglutenics biscuits are intended to those persons who are suffering due to gluten intolerance, also named celiac disease. The fabrication technologies of the aglutenics products can be developed in on two ways: by separating the gluten from the grain or by replacing the grain flour with other types of gluten less flour, in case of bakery and pastry products. In this experiment, the gluten-free biscuits were obtained from the following flours mixture: maize flour (MF), rice flour (RF) and soybeans flour (SF). Other raw materials were used, such as: palmtree oil, honey, maize starch, eggs, sugar powdered, vanilla essence and sodium bicarbonate. Four experimental variants (gluten-free biscuits) were obtained by varying the proportion of flours ; these variants were coded as follows T1, T2 T3 and T4. The optimization of the aglutenics biscuits manufacture recipe was realized through sensory analyze, using the hedonic test (9 point scale). Samples of biscuits was subjected to the following physico-chemical analysis: moisture content, alkalinity, total carbohydrate content, total fat and protein content. Also the physical properties (length, width, thickness, weight and spread ratio) were determined in order to asses the blending influence on the biscuits quality. The blend with flour levels 30:30:40 (MF:RF:SF) led to the highest acceptability
