title: Sunflower seed protein concentrates and isolates obtention from ethanol oil extraction meals--(technical note).
abstract: The objective of this work was to study and identify the necessary processing steps for obtaining good quality sunflower seed protein concentrate and isolate when the oil is extracted with ethanol. This work is part of a research project on using ethanol as renewable solvent for sunflower seed oil recovery and possible further processing of the meal. Both 99 degrees GL and 90 degrees GL ethanol were employed in the extractions to produce the concentrate. Isolates were obtained by treating the concentrate with NaOH and HCl solutions and final rinsing with acidified water. Both products were light in color and almost free from chlorogenic acid.
