The beneficial properties of lysolecithins, however, might be determinable by its chemical composition. Moreover, the lysolecithin composition may interact with the fat type that is used.
Hypothetically, highly saturated fat sources might be better incorporated in micelles by lysophospholipids with a saturated fatty acid due to their physical resemblance.
Therefore, in order to investigate the importance of the lysolecithin composition and its interaction with the fat type, in the present study, 2 lysolecithins with clearly different lysophospholipid profiles (soybean and rapeseed lysolecithin) were combined with 2 distinct
fat types (soybean oil and pig lard). The effects were evaluated in vitro in a fat digestion model and in vivo by a broiler digestibility trial.
