In this work, folic acid was encapsulated using two different matrices and two different encapsulation techniques. This studying showed that electron spraying can be used as a promising technology in the food industry for encapsulation applications since the capsules obtained presented similar morphological characteristics than those obtained through spray drying. Furthermore, it does not require heating or the use of organic agents which could destroy some sensitive encapsulated nutrients or cause toxicity problems. Specifically, results showed that spherical submicron and micron capsules were obtained for all the compositions assayed, although electron spraying generally allowed and enhanced control over the size distribution of the capsules and smaller capsules. Concerning the encapsulation efficiency, it was observed that there were not significant differences between both encapsulation technologies. However, WPC led to higher encapsulation yields than resistant starch, probably because of the interaction between the protein matrix and the folic acid which facilitated the incorporation of the bioactive within the capsules. With regard to the biopolymers used, it was observed that WPC protected the folic acid against the degradation during storage in both situations. On the contrary, resistant starch suspended in aqueous solution. Nevertheless, protection was greater in dryness conditions; hence these capsules might be better applied in dry foods. Regarding the folic acid stability under thermal exposure, even though promising results were obtained, further studies should be carried out order to determine the potential applications.
