Oxidative stability and in vitro digestibility of fish oil-in-water emulsions containing multilayered membranes.

The oxidative stability and lipid digestibility of fish oil-in-water emulsions (d(43); 5.26-5.71 microm) laminated by primary, secondary, and/or tertiary layers of interfacial membranes have been investigated.

Effect of interfacial protein cross-linking on the in vitro digestibility of emulsified corn oil by pancreatic lipase.

The objective of this study was to investigate the influence of globular protein interfacial cross-linking on the in vitro digestibility of emulsified lipids by pancreatic lipase. 3% (wt/wt) corn oil-in-water emulsions stabilized by either lecithin or beta-lactoglobulin were prepared (pH 7). A portion of the beta-lactoglobulin stabilized emulsions was subjected to a heat treatment known to cross-link the adsorbed globular proteins (85 degrees C, 20 min).

Influence of lipid physical state on the in vitro digestibility of emulsified lipids.

The objective of this study was to investigate the influence of the physical state of emulsified lipids on their in vitro digestibility by pancreatic lipase. A 10 wt % tripalmitin oil-in-water emulsion stabilized by sodium dodecyl sulfate (0.9 wt % SDS) was prepared at a temperature (>70 degrees C) above the melting point of the lipid phase (T(m) approximately 60 degrees C).
