| Résumé: | The article investigates the influence of low-fat lecithin, sunflower oil, and dry egg white on the rheological properties and microstructure of gluten-free rice dough and quality indicators of ready-made bread. To determine the effectiveness of the use of these emulsifiers, the bread technology with implementation of enzyme modificated (by amylolytic enzymes) flour starch was used. To assess the rheological state of the dough, its viscoplastic properties (shear stress and effective viscosity of the test systems) were analyzed using a rotary viscometer. The dough microstructure was examined by microscopy. Traditional methods to determine physical and chemical indicators of ready-made bread quality were used. The results showed that the emulsifiers implementation changed the behavior of rice dough, and had the positive effect on the qualitative (specific volume and porosity). It has been found that the use of a combination of emulsifiers from low-fat lecithin, sunflower oil, and dried egg white in rice bread technology in combination with enzymatic modification of flour starch significantly improves the rheological properties and structure of gluten-free dough and provides high indicators of specific volume and porosity of ready-made products. |
