Abstract

We describe in this paper measurements of the partial specific volumes of lipid (upsilon L) and water (upsilon W) in mechanical mixtures of egg yolk lecithin and water over a range of hydrations (5-55 wt% water) that includes the region at which excess water appears. upsilon L and upsilon W are found to be very nearly 1 cm3/g over the entire range. The water activities of the mixtures were also determined and found to be the same as for lipid deposited as oriented multilayers on solid substrates.
