The liposomes with vitamins remained stable after pasteurization,
as demonstrated by oxidative stability, membrane packing,
morphology and size. Besides, SPC systemhad a rheological behavior
similar to a Newtonian fluid whereas that SPC:SA and SPC:CaS presented
a pseudoplastic one. Adding vitamins to SPC:SA and SPC:CaS
systems favored liposomal aggregation and membrane rigidity,
respectively. A relationship was observed between these properties:
if membrane rigidity and/or aggregation increase, favor the pseudoplastic
behavior and the increment of apparent viscosity.
The incorporation of SPC or SPC:CaS did not change the acceptability
of commercial milk. Also, when the potential consumer
beforehand knew the addition of nutritional bioactive compounds, it
generated a positive effect on acceptability for all the formulations.
From all the above discussed, it can be concluded that these
liposomal formulations are suitable for food industry application,
incorporating bioactive compounds and generating functional
chocolate milk.
