Gluten-free laminated baked products: effect of ingredients and emulsifiers on technological quality

Abstract

The aim of this work was to assess the effect of ingredients and emulsifiers on the physical and textural attributes of gluten-free laminated dough pieces and products. Gluten-free flours (soy, rice and cassava), different water levels (76, 68 and 60%), fat samples and emulsifiers (sodium stearoyl lactylate - SSL and diacetyl tartaric acid ester of mono and diglycerides - DATEM) were used to elaborate dough pieces and baked products. Laminated dough samples based on rice/cassava/soy (35:45:20), 60% of water and shortening, presented a high resistance to deformation and showed an inner sheeted structure after baking. The incorporation of the higher doses of SSL and DATEM leads to products of greater specific volume and a tortuous inner conformation due to their layered conformation. This work provides new perspectives into the study of additives with specific action over the components of gluten-free flours and starches, to develop laminated optimum quality products.
