  • Patent number: 6022561
    Abstract: A galactolipid material from wheat, produced by extraction of crushed wheat grains and subsequent chromatography of the extracted material, and having a content of DGDG of 51.5%, was mixed with the polar solvents, water and glycerol in order to test the swellability. The samples, prepared in glass tubes, were alternately mixed with a rod and centrifugated at room temperature until homogeneous. The samples were inspected as to physical appearance after storing for at least a week at room temperature.Results:20% (w/w) of galactolipid material in water gave a slightly yellow, highly viscous dispersion. Small liposomes could be observed in a polarizing microscope. At higher galactolipid concentrations a stiff gel was formed.10% (w/w) of the same lipid material in anhydrous glycerol resulted in the formation of an opaque, highly viscous gel.
