Methods for separation of wheat flour into protein and starch fractions are described. Wheat flour is (1) mixed with water to hydrate the flour and form a cohesive batter or dough, (2) chilled, and (3) mixed and washed with chilled ethanol to separate it into protein and starch fractions. Wheat protein fractions that are equivalent in yield and protein concentration to fractions produced by water washing methods are obtained, while reducing water and energy use. The protein fraction showed improved dough strength.
On décrit des méthodes pour diviser la farine de blé en fractions de protéines et d'amidon. La farine de blé est (1) mélangée avec de l'eau de façon à hydrater la farine et former la pâte, (2) laquelle est refroidie, (3) puis mélangée et lavée avec de l'éthanol pour la diviser en fractions de protéines et d'amidon. On obtient ainsi des fractions protéiniques de blé qui sont équivalentes du point de vue rendement et concentration de protéines aux fractions produites par les méthodes de lavage à l'eau, mais qui utilisent moins d'eau et moins d'énergie. La fraction protéinique a donné une pâte offrant une meilleure résistance.
