Obtención y caracterización de aislados proteicos de colza

Abstract

[ES] Se ha diseñado un proceso de obtención de aislados proteicos a partir de harina de colza desengrasada. El método incluye la extracción básica de las proteínas solubles seguido de una precipitación acida en el punto isoeléctrico. El precipitado es lavado con agua (pH 4.5), etanol y acetona, obteniéndose un aislado proteico con un 86% de proteína y reduciéndose el contenido en polifenoles y azúcares solubles en más de un 90% respecto a la harina desengrasada. El aislado final presenta unas características físico-químicas que lo hacen atractivo para su uso en alimentación y obtención de hidrolizados proteicos.

[EN] A method for the obtention of protein isolates from defatted rapeseed flour has been designed. The process includes a basic extraction followed by a precipitation at the isoelectric point of the proteins. The precipitate is washed with water (pH 4.5), ethanol and acetone, obtaining a protein isolate with 86% of protein and reducing the contents in polyphenols and soluble sugars in more than 90% with respect to the defatted flour. The final product have physico-chemical characteristics that make it atractive to be used as food and for the obtention of protein hydrolizates.
