Effect of using different types of avocado oil in the production of gelatin-based biopolymers Bloom 300

Derived from the high demand in the use of polymers for the preservation or transportation of various products, the need to replace them with environmentally friendly materials arises, thus emerging biopolymers. In the present work, different biopolymers were developed made with avocado oil [commercial, extra virgin and natural], 300° Bloom gelatine and glycerine as a plasticizer. In order to analyse the homogeneity of the plasticized biofilms, they were characterized by UV and infrared, evaluating their absorption, as well as the transmittance in the visible range, in addition the effect of wettability was analysed by measuring the angle of contact on the surface of the biopolymers and by using a thermobalance, the percentage of solids was measured after 90 minutes of exposure. The results showed a good performance, highlighting the films made with Bloom type gelatine and natural oil maintains the best properties.
