The three formulations with vitamins showed a significant increase of the GP values with respect to the systems with FA
(before and after pasteurization). This result agrees with those obtained by other authors, who have shown that VE increases
membrane rigidity (Fukuzawa et al., 1980; Urano et al., 1988.) especially in level of fatty acids chains (Hincha, 2008)
Finally, by comparing each system before and after pasteurization, in both PC and GP parameters, there were no significant differences except for the SPC:SA system with FA, which presented a significant increase in the value of PC. This finding is noteworthy because it shows the thermal stability of the membrane with regard to packaging
