Antioxidant pectin enriched fractions obtained from discarded carrots (Daucus carota L.) by ultrasound-enzyme assisted extraction
(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 ... -
Selective androgen receptor modulators: comparative excretion study of bicalutamide in bovine urine and faeces
(Wiley, 2017-07)Besides their development for therapeutic purposes, non-steroidal selective androgen receptormodulators (non-steroidal SARMs) are also known to impact growth-associated pathways as ligands of androgenic receptors (AR). ... -
Texture and color analysis of lentils and rice for instant meal using image processing techniques
(2016-10)Typical approaches for measuring color and texture properties are mostly timeconsuming. An image-based method was used to evaluate texture and color in lentils and rice subjected to freeze-drying for an instant meal. Cooked ... -
Effect of different freeze drying cycle in Semimembranous and Gluteus Medius bovine muscles: changes on microstructure, colour, texture and physicochemical parameters
(2016)The aim of the present research was to evaluate effects of freeze drying cycle in Semimembranous and Gluteus Medius bovine muscles (sp: Aberdeen Angus) for instant meal. Samples were analysed by Scanning electron microscopy; ... -
High-power ultrasound pretreatment for efficient extraction of fractions enriched in pectins and antioxidants from discarded carrots (Daucus carota L.)
(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 ... -
Microbiological, antioxidant and physicochemical stability of a fruit and vegetable smoothie treated by high pressure processing and stored at room temperature
(Elsevier, 2019-05)This study aims to evaluate the physicochemical, antioxidant and microbiological stability of a fruit and vegetable smoothie treated with a previously optimized high pressure processing treatment (HPP: 630 MPa, 6min, 20 ... -
Influence of cultivar and cutting date on the fatty acid composition of forage crops for grazing beef production in Argentina
(Wiley, 2016-06)The fatty acid composition and total lipids of various forage crops at different cutting dates and seasons, which are used in forage grazing beef production in Argentina, were determined. Three experiments were carried ... -
Efecto de los tratamientos poscosecha en la expresión de proteínas de estrés térmico en tomate Beatriz = Effect of postharvest treatments on the expression of HSPs in tomatoes Beatriz
(Asociación Argentina de Horticultura, 2015)El almacenamiento de frutos de tomates (Solanum lycopersicum L.) a bajas temperaturas permite extender el período de mercadeo. Sin embargo, esta fruta es susceptible de manifestar daño por frío (DF). El objetivo del ... -
