Finally, in milk with SPC:CaS and vitamins, although the triangular test showed differences, this liposomal formulation would not be affecting the acceptability because both milk samples with or without liposomes were not significantly different in trials with panelists that did not know what they were tasting. Again, as in the case of milk with SPC:SA, knowledge of the nutritional promise produced a positive effect with a score significantly higher respect to the milk without liposomes.
From the obtained results, it can be concluded that the addition of liposomes in milk not only adds nutritional value but also, in the case of SPC, does not affect its acceptability or differs from commercial milk. Moreover, in the case of SPC:CaS, it does not only affect the acceptability but it is increased when the nutritional promise is known. Finally, the SPC:SA system, although it has differences and showed lower acceptability, knowledge of the nutritional promise generated a positive effect on the acceptability of milk. Our results demonstrate an excellent acceptability of potential consumers when knowing that they are drinking the functional milk, which means an advantage in the sale and consumption of the product.
