Abstract:

Oil emulsions comprising 10 or 20% soybean oil, 1.2% egg or soybean phosphatides, and 2.25% glycerol in distd. H2O to 100% with pH adjusted to 7-7.5 by NaOH were optimally homogeneous when lecithin comprised phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositols, and lysophosphatidylcholines at a ratio of 6:2:1:0.03; and when the lecithin component was well dispersed in liposome form in the aq. phase prior to emulsion prepn. This dispersion was best obtained by high pressure homogenization (microfluidization) of the emulsifier. [on SciFinder(R)]
