The increased interest in rational nutrition causes, that from many years is observed a growing consumption of bread, and novel food supplemented with health promoting components. For the bread production in Poland mainly wheat and rye cake flours are used, depleted of a many valuable nutrients such as protein, dietary fibre, minerals and vitamins. Because of their unique chemical composition wheat germs are a particularly valuable resource, both for direct consumption and to enhance the nutritional value of food products. The aim of the study was to prepare wheat bread with a 10% addition of commercial stabilized wheat germs. Based on the obtained results, it was found that wheat germs, due to their unique chemical composition, were a particularly valuable resource to supplement the nutritional value of bread. However, germs had detrimental effect on mechanical properties of dough, and on bread quality. Texture of bread crumb and its chemical composition were analysed. It was shown, that germs subjected to fermentation process could be used in wheat bread production as dietary fibre and mineral compound supplement. [ABSTRACT FROM AUTHOR]

Kvass based on traditional technology completely disappeared from polish market. It was replaced by drinks, prepared from malt concentrates, wrongly named kvass. The aim of this study was therefore to obtain traditional bread kvass (by fermentation), using the mash prepared from commercial wholemeal rye bread, produced by 5-phase dough fermentation method, and to determine the quality of this kvass in terms of consumer acceptance, chemical composition and antioxidant activity. It has been demonstrated that based on the traditional wholemeal rye bread, it is possible to produce good quality bread kvass, with similar organoleptic qualities to the commercial kvasses, which contain several added flavours and preservatives. Natural bread kvass can be consumed by consumers of all ages, since it contains only trace amounts of alcohol, and it has almost double the dietary fibre content and three times lower content of reducing sugars as compared to the commercial kvasses. Laboratory made kvasses by natural fermentation also showed an increase in antioxidant activity by 60%, when compared to commercial kvasses. [ABSTRACT FROM AUTHOR]
