  • Heat-stable oil and water emulsion and preparation thereof
    Patent number: 5314706
    Abstract: An egg yolk fortified with exogenous soybean lysophosphatidylcholine contained in exogenous soybean lysophospholipids is employed as an emulsification agent in oil and water emulsions, particularly in emulsions which are sterilized. The agent may be obtained by hydrolyzing phospholipids derived from soybeans with phospholipase A2, deactivating the phospholipase A2 with a proteolytic enzyme and then inactivating the proteolytic enzyme by heat-treatment at a temperature of from 80.degree. C. to 90.degree. C., and then, egg yolk is fortified by combining and homogenizing the so-obtained lysophospholipids, or exogenous phospholipids containing lysophosphatidylcholine otherwise obtained, with egg yolk.
