The production of açaí pulp in Brazil results in over 1 million tons of seeds annually, which make up 85-95% of the fruit’s mass. These seeds primarily comprise mannan (55-65%) and are rich in antioxidants, making them a valuable yet underutilized resource. The goal is to assess the potential of converting açaí seed into energy and products for use in the food and cosmetics industries. The initial phase involves the structural characterization of the seed’s polysaccharides and a detailed identification of antioxidant compounds. This stage will lay the theoretical groundwork for the development of enzymatic or chemoenzymatic conversion methods to produce antioxidant extracts, mannose, and mannan-oligosaccharides. We will also explore the feasibility of producing biogas through the anaerobic digestion of seed components. This could potentially facilitate decentralized energy production in remote areas. This comprehensive approach aims to unlock the full potential of açaí seeds, transforming them from waste material into a source of valuable products and sustainable energy.
