Antioxidant characterization of new dietary fiber concentrates from papaya pulp and peel (Carica papaya L.)
Nieto Calvache, Jhon; Cueto, Mario Alberto; Farroni, Abel Eduardo; Escalada Pla, Marina de; Gerschenson, Lia Noemi (2016)Residues of papaya pulp and peel were used to produce dietary fiber concentrates (DFCs) by treatment with ethanol and microwave drying. The fiber showed antioxidant capacity. Phenolics, carotenoids and ascorbic acid were ... -
Gelling pectins from carrot leftovers extracted by industrial-enzymes with ultrasound pretreatment
Perez, Carolina Daiana; Idrovo Encalada, Alondra Mariela; Gerschenson, Lia Noemi; Rojas, Ana Maria; Fissore, Eliana Noemi (Elsevier, 2019-05-17)Misshapen carrots were upgraded as orange-colored pectin-enriched fractions (PEFs) useful as gelling agents and containing α- and β-carotenes, lutein, and α-tocopherol, by applying a green process consisting of an ultrasound ... -
High methoxyl pectin–methyl cellulose films with antioxidant activity at a functional food interface
Perez, Carolina Daiana; De'Nobili, Maria Dolores; Rizzo, Sergio Anibal; Gerschenson, Lia Noemi; Descalzo, Adriana Maria; Rojas, Ana Maria Luisa (2013-05)The effect of using increasing proportions of methylcellulose (MC) for the development of glycerol plasticized films based on high methoxyl pectin (HMP) (30:70, 50:50 and 70:30 w/w HMP:MC) and carrying l-(+)-ascorbic acid ... -
High-power ultrasound pretreatment for efficient extraction of fractions enriched in pectins and antioxidants from discarded carrots (Daucus carota L.)
Idrovo Encalada, Alondra Mariela; Perez, Carolina Daiana; Alzate Calderón, Paola; Zukowski, Enzo; Gerschenson, Lia Noemi; Rojas, Ana Maria Luisa; Fissore, Eliana Noemi (Elsevier, 2019-03)A useful pectin-enriched fraction (PEF) extracted through high-power-ultrasound (HPUS) pretreatment and sodium carbonate was efficiently obtained from discarded carrots. Formerly, the effect of HPUS-power intensity and ... -
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, ...
