SUNFLOWER SEED PROTEIN-CONCENTRATES AND ISOLATES OBTENTION FROM ETHANOL OIL EXTRACTION MEALS

The objective of this work was to study and identify the necessary pro cessing steps for obtaining good quality sunflowerseed protein concent rate and isolate when the oil is extracted with ethanol. This work is part of a research project on using ethanol as renewable solvent for s unflower seed oil recovery and possible further processing of the meal . Both 99-degrees-GL and 90-degrees-GL ethanol were employed in the ex tractions to produce the concentrate. Isolates were obtained by treati ng the concentrate with NaOH and HCI solutions and final rinsing with acidified water. Both products were light in color and almost free fro m chlorogenic acid.
