Sacha inchi (Plukenetia volubilis) is a native plant growing in Peruvian Amazon Rainforest. The sacha inchi fruit has an important nutrition values due to high content of essential fatty acid, i.e. omega-3 and omega-6, vitamin and E (natural antioxidant) [1]. In this studyh, the micro and nano emulsions of chitosan-alginate were prepared using ultrasound in the presence of sacha inchi oil (5% of total volume). To compare the effect of sach inchi oil in the formulation of particles, other edible oils were also tested like commercial vegetable oil and olive oil, all produced in Peru. Various reaction factors were optimized such as, sonication time and temperature, pH of chitosan and alginate solutions, concentration of surfactant, and concentration of chitosan. The obtained micro and nanoparticles were characterized by measuring the particle size, zeta potential and polydispersity using zeta-sizer. The content of sacha inchi oil in chitosan-alginate particles was observed by measuring FT-IR. The morphology of particles was studied with optical microscopy with x100 objective. The loading efficiency of BSA molecules was studied and increased with BSA concertation. The antioxidant activity of resulting chitosan-alginate particles were tested by ABTS decoloration method and showed a strong antioxidant acitvity when the chitosan-alginate particles were prepared with sacha inchi oil.
