[Influence of technological processes on the extractability of phenols and carbohydrates from sunflower meal and related protein solubility].

Abstract

A chemical method for the removal of chromogenic phenolic constituents and carbohydrates of the sunflower meal has been investigated. This method uses a nondenaturing polar solvent formed by n-butanol saturated by diluite HCl and allows the preparation of protein isolate off-colour free. Evaluations on the extractibility of phenols, carbohydrates and proteins of sunflower meals from different technological processes have been carried out.
