Resumen
Recent studies have shown that it should be possible to control lipid bioavailability through food
structural approaches. Nevertheless, the gastrointestinal-tract physiological conditions must also be considered.
To get a better understanding of this phenomenon, we evaluated the effect of emulsification, as
well as the use of sodium caseinate or chitosan, on the postprandial bioavailability of interesterifiedlipids
in O/W emulsions after oral gastric feeding Sprague–Dawley rats. We verified that emulsification
may increase lipid absorption, as determined after feeding sodium-caseinate emulsions. However, this
result could not be generalised. Interesterified-lipids that were emulsified with chitosan were equally
absorbed as those contained in non-emulsified interesterified-lipids/distilled-water blends.
