Effect of the addition of phytosterols and tocopherols on Streptococcus thermophilus robustness during industrial manufacture and ripening of a functional cheese as evaluated by qPCR and RT-qPCR
Pega, Juan Franco; Rizzo, Sergio Anibal; Perez, Carolina Daiana; Rossetti, Luciana; Diaz, Gabriela; Ruzal, S.M.; Nanni, Mariana; Descalzo, Adriana Maria (2016-09)The quality of functional food products designed for the prevention of degenerative diseases can be affected by the incorporation of bioactive compounds. In many types of cheese, the performance of starter microorganisms ... -
Impact of extracellular nucleic acids from lactic acid bacteria on qPCR and RT-qPCR results in dairy matrices : implications for defining molecular markers of cell integrity
Pega, Juan Franco; Descalzo, Adriana Maria; Rossetti, Luciana; Nanni, Mariana; Perez, Carolina Daiana; Rizzo, Sergio Anibal; Diaz, Gabriela Perez (2017-07)In this study, we evaluated whether quantitative PCR (qPCR) and reverse transcription-qPCR (RT-qPCR) results could be affected by extracellular (free) DNA or RNA, respectively, obtained either from isolated bacteria or ... -
Impacto de la incorporación de lípidos vegetales y antioxidantes sobre el comportamiento del starter durante la producción industrial de un queso funcional evaluado por técnicas independientes de cultivo
Pega, Juan Franco; Rizzo, Sergio Anibal; Rossetti, Luciana; Perez, Carolina Daiana; Diaz, Gabriela Esther; Ruzal, S.M.; Descalzo, Adriana Maria; Nanni, Mariana (2019)Los fitoesteroles son un conjunto de lípidos vegetales que han sido utilizados para el diseño de productos lácteos funcionales debido a su capacidad para reducir el colesterol sérico. No obstante, su efecto sobre el ... -
Oxidative status of a yogurt-like fermented maize product containing phytosterols
Descalzo, Adriana Maria; Rizzo, Sergio Anibal; Servent, Adrien; Rossetti, Luciana; Lebrun, Marc; Perez, Carolina Daiana; Boulanger, Renaud; Mestres, Christian; Pallet, Dominique; Dhuique-Mayer, Claudie (2018-05)This work describes the formulation of a functional yogurt-like product based on fermented maize with added phytosterols and its oxidative stability during cold storage. The technological challenge was to stabilize 3.5% ... -
Plum (Prunus salicina) peel and pulp microparticles as natural antioxidant additives in breast chicken patties
Basanta, Maria Florencia; Rizzo, Sergio Anibal; Szerman, Natalia; Vaudagna, Sergio Ramon; Descalzo, Adriana Maria; Gerschenson, Lia Noemi; Perez, Carolina Daiana; Rojas, Ana María (2018-04)Fiber microparticles (MPCs) separately obtained from peel and pulp of Japanese plum residues contained co-extracted β-carotene, lutein, and α- and γ-tocopherols, as well as polyphenols (cyanidins, quercetin derivatives, ... -
The incorporation of alpha-tocopherol and functional doses of phytosterol esters during cheesemaking does not affect DNA or mRNA dynamics of Streptococcus thermophilus and Lactococcus lactis throughout and after the end of ripening
Pega, Juan Franco; Descalzo, Adriana Maria; Rossetti, Luciana; Nanni, Mariana; Perez, Carolina Daiana; Rizzo, Sergio Anibal; Diaz, Gabriela; Ruzal, Sandra Monica (2017-10)Tocopherols and phytosterols are lipid-soluble molecules which have been widely used in the food industry. Nevertheless, the influence of these compounds on the performance of starter lactic acid bacteria (SLAB) in fermented ...
