- Abstract
Background. Cereal products, including bread, play an important role in our daily diet and are a source of energy, nutrients and health promoting components. Consuming bread of the best possible quality is an important element of preventive treatment in times marked by the increasing number of diet-related diseases in the society. There is also a need to research the quality of bread assortment available on the market. As a result, consumers will have access to information on the benefits of consuming high-quality food and will be able to choose an assortment tailored to their own needs. The aim of this work was to assess the diversified content of nutrients and bioactive ingredients in popular types of bread available on the Polish market. Moreover, it was demonstrated how ingredients used for baking bread affected the chemical profile of the finished product. Results and conclusion. Eight commercial samples of bread with different composition declared on the labels were tested. In all samples the following nutrients were marked: protein, ash, lipids and starch, as well as bioactive components: dietary fiber broken down into insoluble and soluble fractions, total phenolic compounds and antioxidant activity. The analyzed breads differed significantly in terms of chemical composition, which resulted from the amount of raw materials used in production, production technology and additives used. The research showed that out of all samples covered by the analysis the whole meal rye bread had the best composition and contained the highest content of ash (3.9 %), dietary fiber (15.2 %) and β-glucan (1.6 %), as well as high antioxidant activity (5.5 mg Trolox/g). The wheat roll had the least favorable properties -- it had the highest lipid content (3.4 %) and contained the lowest level of ash (2.3 %) and most bioactive compounds (dietary fiber 5.6 %, lignin 0.2 %, resistant starch 1.2 %, total phenolic compounds 0.5 mg GAE/g and antioxidant activity 2.4 mg Trolox/g).
