Bakery products, especially breads, are important part of everyday diet. Home-made breads are all the more crucial on the gluten-free diet, as commercially available breads without gluten are often unattractive. The study presents the recipe, nutritional characteristics (fat, protein, calcium, magnesium, sodium, potassium, copper, iron, zinc, manganese), costs and consumer acceptance of four easy to make homemade gluten-free breads. Partial substitution of bread-mix based on corn and rice (control bread) with teff flour, amaranth flour or quinoa flour significantly changed the content of the most of analysed nutrients, while their price was comparable. The highest nutritional benefits were found for protein, magnesium, potassium, calcium, zinc, iron and manganese in bread with teff and for magnesium, potassium, zinc and manganese in bread with amaranth. The highest consumer acceptance of people on gluten-free diet was noticed for breads with quinoa and teff.
Globalization leads to modernizing food habits and the substitution of the traditional foods by industrialized foods in the diets of Europeans is constantly growing. The main factor shaping the demand for traditional, regional and ecological food is its availability, price and ecological awareness of the society. Polish consumers are increasingly turning to traditional and organic food, perceiving it as healthier, safer and tastier than commercial industrialized food. In the European Union Protected Designation of Origin, Protected Geographical Indication, Traditional Specialities Guaranteed promote and protect the names of agricultural products and foodstuffs since 1992. The main factor limiting demand for traditional, regional and organic food is its high price, hence the market for these products should be shaped, inter alia, by protecting and promoting products and highlighting their high health and taste values.
This paper presents the results of research on the possibility of photodecolourization of trace amounts of copper complexes of chlorophyllins (E141(ii) commercial dye) in water (sewage). Experiments were carried out in model UV-VIS/E141 (ii)/TiO 2 /H 2 O and UV-VIS/E141(ii)/H 2 O systems. The degree of decolourization of the dye was determined spectrophotometrically. The loss of dye in a UV-VIS/E141(ii)/TiO 2 /H 2 O system was directly proportional to the initial substance concentration and ranged from 55% to 82%, depending on the initial concentration of the dye in the solution. Kinetic studies confirmed that over a range of examined concentrations of dye E141(ii), the photocatalytic decolourization process occurs in accordance with the commonly acknowledged Langmuir-Hinshelwood model. The course of changes in pH upon exposure indicates the formation of acidic derivatives of chlorophyllins. We found that the amount of photodegradable dye strongly depends on the initial pH of the solution. The increase of the pH of the solution inhibited the process of photocatalytic decolourization of E141(ii), whose yield reached a minimum value at pH 8. Results of this study confirm that the photocatalytic processes can be an alternative to traditional methods of food industry sewage treatment.
Miód charakteryzuje się unikatowymi właściwościami sensorycznymi i prozdrowotnymi. W skład miodu wchodzą między innymi przeciwutleniacze, enzymy, witaminy, makro- i mikroelementy, które kształtują jego aktywność biologiczną i odgrywają kluczową rolę w prawidłowym funkcjonowaniu organizmu. Miody stanowią źródło potasu, magnezu, wapnia, sodu, siarki, manganu, żelaza, wanadu, chromu, fosforu, srebra, boru i miedzi. Celem pracy było określenie składu mineralnego miodów odmianowych dostępnych na polskim rynku. W badaniach użyto polskich miodów różnych odmian: akacjowego, wielokwiatowego, lipowego i rzepakowego. Ocenie poddano miody zakupione w supermarkecie i pochodzące bezpośrednio z pasieki. Średnia zawartość Ca, K, Na, Mg, Mn, Zn, Cu i Fe w miodach wynosiła odpowiednio [mg/100 g]: 7,42, 59,66, 1,57, 1,44, 0,11, 0,46, 0,02 i 0,12. Największą zawartością makro- i mikroelementów charakteryzował się miód wielokwiatowy pochodzący bezpośrednio z pasieki – 133,77 mg/100 g. Najmniejszą zawartość składników mineralnych wykazano w miodzie akacjowym zakupionym w supermarkecie – 27,23 mg/100 g. Dodatkowo przeanalizowano wpływ położenia prywatnej pasieki w okolicach Huty Miedzi Głogów na zawartość miedzi w próbach miodów różnych odmian. Nie stwierdzono statystycznie istotnej różnicy (p ≥ 0,05) pomiędzy średnią zawartością miedzi w miodach komercyjnych i w miodach z prywatnej pasieki, co wskazuje na brak wpływu pochodzenia geograficznego na zawartość tego pierwiastka.
