    Evaluación de la producción de concentrados proteícos y sus propiedades funcionales usando diferentes variedades de arvejas (Pisum Sativum L.)
    (2024) Accoroni, Cecilia; Espósito, María Andrea; Guraya , María de los Ángeles; Batres, Rocío; Godoy, Ezequiel
    El objetivo del trabajo ha sido evaluar el comportamiento de producción de productos proteicos durante tres años de nueve variedades diferentes de arvejas verdes y amarillas; una comercial (Primogénita) y dos precomerciales (B320 y B313) del programa de mejoramiento INTA-FCA UNR en comparación con seis comerciales (Reussite, Viper, Kingfisher, Aragorn, Meadow y Astronaute).

    Impacto de la fermentación en estado sólido con Aspergillus niger en el contenido proteico de arvejas amarillas (Pisum Sativum L.)
    (UNER, 2024) Guraya, María de los Ángeles; Batres, Rocío; Torresi, Pablo Antonio; Reinheimer, María Agustina; Godoy, Ezequiel
    Esta investigación se centró en evaluar el impacto de un proceso de fermentación en estado sólido (FES) con Aspergillus niger sobre la concentración proteica de harina de arveja amarilla. El proceso de FES se llevó a cabo en un biorreactor de columna estéril.

    Protein recovery from yellow peas (Pisum sativum L.) for enhanced processing sustainability and functional properties.
    (2024) Guraya, María Ángeles; Andrín, María Nieves; Batres, Rocío; Torresi, Pablo Antonio; Godoy, Ezequiel; Reinheimer, María Agustina
    This research focuses on sustainable protein recovery methods from a new yellow pea variety by examining alternative pH-shifting processes. The study focuses on reducing water consumption during alkaline extraction by adjusting solid-liquid ratios, and evaluating the impact of various isoelectric precipitants, including lactic acid and lactic acid bacteria (Lactobacillus plantarum and Lactobacillus lactis), on the functional and antioxidant properties of products across a wide range of pH values. It was here found that the process alternative with three 1:10 (w/v) extraction cycles and lactic acid bacteria as precipitant agent achieved high process productivity (0.36 kg protein product/kg pea flour) and low specific water consumption (94.9 kg water/kg protein product). No significant differences were observed in protein content and yield when compared to other flour-water ratios with higher water consumption or less eco-friendly precipitants. Products precipitated with lactic acid bacteria formed stable emulsions even at the isoelectric point, exhibited superior free radical scavenging activity, although solubility and water holding capacity were lower, and no differences were noted in oil holding capacity, foaming capacity, and foam stability.
