Fermented unripe cornelian cherry as a functional food
(Lodz University of Technology Press, 2015) Czyżowska, Agata; Kucharska, Alicja; Nowak, Agnieszka; Motyl, Ilona
Consumer trends are changing due to the increasing awareness of the link between diet and health. The largest segment of the functional food market comprises foods fortified with probiotics, prebiotics and synbiotics. Fruits already containing high levels of beneficial substances can be reinforced with probiotic bacteria that can bring about additional health promoting features. Cornelian cherry (Cornus mas L.) fruits are rich sources of polyphenols and iridoids, valuable for fresh consumption or processing. Unripe fruits is manufactured by Arboretum in Bolestraszyce as a traditional product. The aim of this work was to evaluate the probiotic strains in order to determine their potential in the development of new starter cultures for functional food – green fermented cornelian cherry.
Functional ice cream with a "clean label"
(Wydawnictwo Politechniki Łódzkiej, 2019) Motyl, Wojciech; Dziugan, Piotr; Motyl, Ilona; Jóźwiak, Aleksandra; Nowak, Szymon
High market competitiveness as well as in creased interest in health-related products forces producers to create new products and innovative production technologies that would encourage a potential customer to buy. The idea of "clean label" enjoys growing popularity due to the strong in terest in healthy, unprocessed products and simple ingredients. Currently, products of this type are not yet very popular in the assortment of ice cream available on the Polish market. Ice cream enriched with selected nutrients are in accordance with prevailing dietary trends. An interesting proposal to increase the health value of ice cream may be the introduction of vitamins, mineral preparations and dietary fiber into their composition. The pro-health activity of dietary fiber is related to their beneficial effects on human intestinal microflora. From technological point of view, ice cream with the addition of fiber preparation was characterized by a significantly longer melting time than ice cream without fiber. Another way to enrich the ice cream is the addition of probiotics. Consumption of probiotic-containing ice cream can have a positive effect on human health mainly through immune system. In order to achieve the desired health effect as a result of consumption of probiotic ice cream, it is necessary to ensure therapeutic minimum related to ensuring the minimum number of viable cells of probiotic bacteria n ecessary to guarantee the beneficial effects of probiotic microflora on the human body (e.g. milk fermented beverages, the therapeutic minimum is 10⁶-10⁷ CFU/g).
In vitro anti-adherence effect of probiotic Lactobacillus strains on human enteropathogens
(Lodz University of Technology Press, 2017) Nowak, Adriana; Motyl, Ilona
Probiotic bacteria possess great potential for producing antimicrobial substances that inhibit and control pathogenic bacteria in the human gastrointestinal tract. The aim of this study was to determine the anti-adherence properties of the probiotic Lactobacillus strains Lb. rhamnosus ŁOCK 0900, Lb. rhamnosus ŁOCK 0908, and Lb. casei ŁOCK 0919 (individually and in a 1:1:2 mixture) against the reference pathogens Clostridium difficile (ATCC 9689), Enterococcus faecalis (ATCC 29212), Listeria monocytogenes (ATCC 19115), and Staphylococcus aureus (ATCC 6538) using the Caco-2 human colon adenocarcinoma cell line. The mixture of probiotic strains inhibited the adherence of all pathogens, from 10.2% for E. faecalis ATCC 29212 to 97.2% for L. monocytogenes ATCC 19115. Of all the tested probiotic strains, Lb. casei ŁOCK 0919 reduced the adherence of S. aureus ATCC 6538 to the greatest extent (by 45.9%). These results suggest that adherence inhibition may involve competition for eukaryotic cell receptors and probiotic bacteria could protect the host cells from pathogen colonization and disease.
