Nowadays, there is interest about natural biopolymers characterization and their use for the development of bioplastic in order to replace petroleum-derived plastics, which are hard to decompose or have negative impact on the environment. This work focuses on the characterization of the mucilage of the cactus Echinopsis pachanoi (E. pachanoi) and development of bioplastics from mucilage E.pachanoi and algae from Peruvian coast such Ulva nematoidea and Chondracanthus chamissoi. An effective process for obtaining E. pachanoi mucilage powder was developed. FTIR, DSC and TGA tests of the mucilage powder allowed to know its initial characteristics. Likewise, the rheological studies of the E. pachanoi gel resulted in a predominantly elastic behavior and reversible deformation. Films based on blends of E. pachanoi mucilage, ulva and carrageenan were made developed. The main results indicated that mucilage promote, depending on the type of the mixture, the modification of the thermic and mechanical properties of the films. In the case of the film of mucilage and carrageenan, a more flexible and less resistant material is obtained; on the contrary, the mixture with ulvan, more rigid and resistant material is obtained. The present work results indicate that biopolymers as E. pachanoi mucilage, carrageenan, which are abundant, renewable, biodegradable and non-toxic materials for humans, can be used to manufacture bioplastics that, in the future, they can cover demands for edible coatings and other uses.
