    Doxycycline is an antibiotic of great interest in the health area, since it serves as a treatment for a variety of bacterial infections, but it has a drawback since it tends to degrade very easily at the time of its production, that is why new alternatives have been sought to preserve its bioactive components and protect it from contamination and even increase its bioavailability with the help of microencapsulation which is a technique that uses encapsulating materials such as natural polymers in order to generate greater effectiveness in encapsulation. For this, three suspensions were made with different proportions, using analysis techniques and verification of microencapsulation efficiency which were, performance analysis, statistical analysis, thermograms by means of differential scanning calorimetry (DSC) and antimicrobial evaluation, which was carried out by means of antibiograms of diffusion disks in Müller Hinton agar, to determine the inhibition of the microencapsulate against the E. coli bacteria. Through the different analyses carried out, it was obtained that the best performance and inhibition halos were given in the proportion 20:80, in addition to this, through the thermograms it was possible to observe the melting peaks where it was also represented that the best curve was that of the proportion 20:80. This is thanks to the fact that with a higher polymeric load, the percentage of microencapsulation efficiency increases. This could also be observed with the help of an-ANOVA analysis, which allowed the most significant performance to be seen through statistical graphs.
