| Abstract : | The aim of this work was to determine the baking value of rye flour type 500 from Polish industrial mills obtained in 2013. The ash content, protein content, granulation, farinograph water absorption, falling number, amylograph properties and pentosans contents (total, soluble and insoluble) were determined. The laboratory baking test was also performed. Volume of bread, and crumb acidity, hardness as well as moisture content were determined. It was found that the examined rye flour were significantly different in terms of all parameters which characterised their baking value. The Falling Number value indicated that the examined rye flours were of low amylolitic activity. Breads with the highest volume were obtained from samples of flour which were characterised by high water absorption and the highest percentage of soluble pentosans. Breads obtained from rye flour samples characterised by high total pentosans content had more moist crumb. The mostly preferable was bread obtained from rye flour which was characterised by high water absorption, high total pentosans content and high percentage of soluble pentosans. Bread made of this flour was characterised by high volume, the highest crumb moisture as well as the lowest hardness of bread and the lowest increase of hardness during the storage of bread. |
