《Rheological, textural and sensory properties of gluten-free bread formulations based on rice and buckwheat flour》 Mixolab, as the rheological instrument, was utilized to create gluten-free products. According to obtained Mixolab profiles, mixtures of rice flour and husked buckwheat and rice flour and unhusked buckwheat flour expressed rheological properties similar to wheat flour. In both types of mixtures the ratio of rice flour to buckwheat flour was 90:10, 80:20 and 70:30. According to the Mixolab profiles of the investi¬gated systems, gluten-free products containing unhusked buckwheat flour had higher water absorption values, lower stability and weaker protein network structure, as well as lower peak viscosity than those consisted of husked buckwheat flour. Increasing the amount of husked buckwheat flour from 10% to 20% resulted in both G0 and yield stress value increase, but further increase of the husked buckwheat flour on 30% resulted in both G0 and yield stress value decrease. However, increasing the amount of unhusked buckwheat flour from 10% to 20% resulted in significant decrease of G0 and yield stress value having no significant impact with the addition of 30% of unhusked buckwheat flour. Hardness, expressed as a work of compression of the final product, increased with the amount of both types of buckwheat flour. Samples containing UBF expressed not significantly higher values of hardness than those prepared with HBF. According to obtained results of sensory evaluation of the final products it can be concluded that all six combinations of tested gluten-free breads were sensory acceptable. 如需阅读全文，请来函索取！ 联系方式：info@chopinchina.com
