Flour was milled from normal and degermed wheat of three Canadian varieties. Thatcher, Lemhi, and Mindum. These flours were extracted serially with hexane and water-saturated n-butanol (WSB) to yield "free" and "bound" lipid, and with WSB directly to yield total lipid. All extractions were carried out in the cold 1-5 C.), under nitrogen. Two methods of removing nonlipid material were compared. The yield of lipid, its atomic nitrogen/phosphorus ratio, and its chromatographic purity were determined. The present procedure was compared with other methods for removal of lipid from wheat flour.
