PURPOSE:To obtain protein having improved emulsifying ability, by homognizing protein and lecithin in an aqueous system to prepare a lecithin-protein conjugated material, changing its high-order structure and converting it into a high-molecular material. CONSTITUTION:In an aqueous system, protein (preferably soybean protein) and lecithin (e.g., soybean lecithin, lecithin of egg yolk, lecithin of microorganis, etc.) is homogenized by the use of a homogenizer, etc., to prepare a lecithin-protein conjugated material. The material is then treated with a polar organic solvent such as ethanol, etc., further heat-treated, so that its high-order structure is changed, and it is converted into a high-molecular material, to give protein consisting of a lecithin-protein conjugated material, having improved emulsifying ability. |
