Antioxidant pectin enriched fractions obtained from discarded carrots (Daucus carota L.) by ultrasound-enzyme assisted extraction
Idrovo Encalada, Alondra Mariela; Perez, Carolina Daiana; Flores, Silvia K.; Rossetti, Luciana; Fissore, Eliana Noemi; Rojas, Ana Maria Luisa (2019-03-19)Carrot residues were upgraded as pectin-enriched fractions (PEFs) useful for functional food formulation due to co-extracted antioxidants (α- and β-carotenes, lutein, α-tocopherol), and gelling effect. High power ultrasound ... -
Antioxidant pectins from eggplant (Solanum melongena) fruit exocarp, calyx and flesh isolated through high-power ultrasound and sodium carbonate
Higuera Coelho, Ricardo Alejandro; Basanta, María Florencia; Rossetti, Luciana; Perez, Carolina Daiana; Rojas, Ana María Luisa; Fissore, Eliana Noemi (Elsevier, 2023-06)Dried and milled eggplant fruit peel and calyces (PC) and mesocarp, placenta and core (Mes) were utilized as natural sources of valuable chemicals. Pectins were extracted with 0.1 M Na2CO3 (1 h; 23 °C). A high-power ... -
Antioxidant status and odour profile in milk from silage or lucerne-fed cows
Rossetti, Luciana; Langman, Leandro Ezequiel; Grigioni, Gabriela Maria; Biolatto, Andrea; Sancho, Ana Maria; Comeron, Eduardo Alberto; Descalzo, Adriana Maria (Dairy Industry Association of Australia, 2010-04)In order to determine the effect feeding differences on natural antioxidant vitamin delivery, two contrasting diets, lucerne (ALF) and sorghum silage (SS), were analysed. Diets showed different profiles for fat-soluble ... -

Pouzo, Laura Beatriz; Descalzo, Adriana Maria; Zaritzky, Noemi Elisabet; Rossetti, Luciana; Pavan, Enrique (2016-01)Angus steers were grazed on unsupplemented pasture (CNTRL), pasture supplemented with 0.7% BW cracked corn (FLAX-0), FLAX-0 with 0.125% and 0.250% BW of whole flaxseed (FLAX-1 and FLAX-2). Six steers were grazed per treatment ... -
Carrot pectin enriched fraction as a functional additive: Antioxidant and gelling effects in a model spreadable chia oil-in-water emulsion
Idrovo Encalada, Alondra M.; Perez, Carolina Daiana; Rossetti, Luciana; Rojas, Ana M.; Fissore, Eliana N. (Elsevier, 2020-05-15)An orange-colored pectin-enriched fraction previously obtained from discarded carrots (CPEF; 42%-methylated, 14%-acetylated, 50% uronic acids) through high-power-ultrasound and bacterial hemicellulase, carrying carotenes, ... -
Comparison of the quality attributes of carrot juice pasteurized by ohmic heating and conventional heat treatment
Negri Rodriguez, Livia Maria; Arias, Ricardo; Soteras, Trinidad; Sancho, Ana Maria; Tacca, Hernán; Aimaretti, Nora Rosa; Rojas Cervantes, María Luisa; Szerman, Natalia; Pesquero, Natalia; Rossetti, Luciana (2021-03-04)This study aimed to evaluate the effect of pasteurization of carrot juice by heat treatment (80 °C – 7 min) and ohmic heating (OH) on its physicochemical and chromatic parameters, enzymatic and microbiological inactivation, ... -
Desarrollo y escalado del proceso de producción de un queso de pasta blanda light funcional debido a la incorporación de fitoesteroles y alfa-tocoferol
Rizzo, Sergio Anibal; Rossetti, Luciana; Descalzo, Adriana Maria (PUBLITEC S.A. Argentina, 2023-04)The objective was to study the shelf life and monitor the oxidative parameters of salut light cheeses added with phytosterols (EF) and natural tocopherols (TF) produced on a pre-commercial industrial scale, which were ... -
