Abstract	The design of new functional foods with nutritional and/or health claims often requires the encapsulation, protection and subsequent controlled release of bioactive molecules. Among the most novel encapsulation systems, laminar nanoclays are receiving great attention due to their ability to encapsulate a large quantity of an active compound and release it in a controlled way to the medium. The objective of this study is to characterize three types of nanoclays (montmorillonite, hectorite and saponite) and to evaluate the impact of their incorporation, both nude and functionalized with amines, in gelatin gels. On the one hand, nanoclays were characterized according to their morphology, particle size distribution and zeta potential, observing that functionalization with amines modified the surface charge of the particles. On the other hand, the rheological properties of the gels were evaluated by oscillatory tests with temperature sweep. The results have shown that the addition of both naked and functionalized particles at a 1% concentration does not modify the gelation temperature of the gel to which it is added, nor the viscoelastic properties of the resulting gel when the particles are functionalized with amines. In this way, their incorporation as controlled release systems would not significantly modify these properties of the food in which they could be added.
