Pozycja Antioxidant activity of beers produced with unmalted quinoa and amaranth(Lodz University of Technology Press, 2015) Bogdan, Paulina; Kordialik-Bogacka, EdytaQuinoa and amaranth are pseudocereals, which recently have received increased interest, as they are a good source of different nutrients, including proteins, vitamins and other biologically active compounds. They are also rich in antioxidants such as polyphenols, known to inhibit oxidation reactions in foods and beverages, and vitamin E[1]. Due to a high starch content quinoa and amaranth can be a potential substitute of barley malt in brewing. During beer storage there is a deterioration of beer quality since many undesirable flavours occur. [2]. Since quinoa and amaranth are an excellent source of antioxidants, their use in beer production might extend the shelf life of final products. The aim of this study was to investigate the antiradical and reducing potential of beers produced with 10 and 30% addition of unmalted amaranth and quinoa. Moreover, a relationship between the antioxidant capacity and total polyphenol content in beer was evaluated.Pozycja The impact of the changes in surface properties of yeast biomass, Saccharomyces cerevisiae, on Pb2+ biosorption(Lodz University of Technology Press, 2016) Kordialik-Bogacka, Edyta; Diowksz, AnnaThis study examines changes that occur in yeast cell surface properties during physical, chemical and mechanical treatment and their potential impact on the biomass uptake capacity for lead. As a result of biomass treatment, the negative surface charge decreased and relative hydrophobicity increased. A strong negative correlation was discovered between the negative surface charge of variously modified yeast cells and their relative hydrophobicity. Despite the lower negative surface charge of treated in comparison to untreated yeast cells, the treated biomass had higher lead sorption capability. No relationship was found between the effectiveness of lead sorption by treated biomass and its surface charge or relative hydrophobicity.Pozycja Napój z herbacianego grzybka(Wydawnictwo Politechniki Łódzkiej, 2021) Kordialik-Bogacka, EdytaPolitechnika Łódzka jest partnerem projektu, którego celem jest wdrożenie innowacyjnej technologii produkcji kombuchy.
