The use of byproducts generated during fish processing has enormous potential for obtaining innovative materials that can be used in bioactive encapsulation systems. The objective of this study was to obtain and characterize gelatin from Doncella (Pseudoplatystoma fasciatum) skin as its use as a covering material together with arabic gum in the production of microparticles by complex coacervation, containing aguaje oil as active material (MA). Gelatin obtained from Doncella skin (GD) was characterized in relation to its extraction yield, centesimal composition, melting point, texture profile, gel strength and molar mass distribution. Likewise, the microparticles produced were evaluated in terms of their morphology, average diameter and encapsulation efficiency (EE). Also, commercial porcine gelatin (GP) was used in both trials for the respective physicochemical comparisons. It was found that GD had a melting point of 29.1 °C, molar mass with defined bands (200 KDa, 150 KDa and 120 KDa) and gel strength of 228.9 g. On the other hand, the use of different stoichiometries in relation to the active material (50%, 75% and 100%) influenced on the %EE; as the concentration of active material was increased the %EE decreased. Also, the application of different speeds of homogenization did not produce significant differences in relation to %EE (p>0.05). The mean diameters of the microparticles produced with GD and GP were 117.40 μm±38.05 and 105.39 μm±37.93, respectively. We can conclude that Doncella skin gelatin is an encapsulating material with characteristics similar to porcine gelatin, in this way the production of coacervated microparticles for food applications is promoted.
