    In vivo postprandial bioavailability of interesterified-lipids in sodium-caseinate or chitosan based O/W emulsions
    (2015) Farfan, M.; Villalon, M. J.; Ortiz, M. E.; Nieto, S.; Bouchon, P.
    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 interesterified-lipids 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. (C) 2014 Published by Elsevier Ltd.
