The purpose of this study was to design the formula and antioxidant potential of gluten-free oat drinks fortifi ed with bioactive plant components. The paper describes the use of three preparations of plant origin: yellow tea leaf extract, mulberry extract and steviol glycosides from stevia leaves. Analyses of the oat drinks basic composition – including proteins, lipids, carbohydrates, dietary fi ber fractions and antioxidant properties with DPPH, ABTS, ORAC and FRAP assays were conducted. Tea extract with steviosides oat drink showed the highest total phenolic concentration and the highest antioxidant activity followed by stevia and mulberry oat drink, whereas stevia oat drink showed the lowest phenolics level and weakest antioxidant activity. Moreover, the applied plant components showed moderate ability to influence the sensory values of the fortifi edoat drinks. The results demonstrate that tea, stevia and mulberry preparations applied in oat drinks enhanced antioxidant potential and might be a natural source of antioxidant components.
Poland's accession to the EU has accelerated the development the domestic food market. The market capacity, demand and supply increased. It did not result from growing consumption of food but from increasing degree of agricultural product processing as well as from growing share of food industry in satisfying the consumers' needs. The linkages between the domestic market and the EU and world markets have tightened. Since there is a general upward trend in food prices in the word, tightening linkages may bring up a demand barrier on Polish food market because of high prices.
