Abstract

The agro-industrial sector is responsible for the generation of a high amount of solid by-products, which usually does not receive an environmentally appropriate treatment. The reuse of these by-products is an alternative to minimize the negative effects generated in the environment, in addition to promoting economic growth, since many of these by-products can be used as sustainable feedstock to produce value-added products. The use of subcritical water technology has been considered a clean, sustainable, and renewable alternative to obtain precursors of biofuels and bioproducts. Therefore, the objective of this project is to evaluate the use of subcritical water technology for the extraction and hydrolysis of pitaya agro-industrial by-products to produce fermentable sugars, organic acids, bioactive compounds, and fructo-oligosaccharides. Finally, the extracts and hydrolysates obtained by subcritical technology will be purified through the adsorption process, aiming at the production of these value-added products with a high degree of purity. Therefore, with this project it is expected the development and optimization of sustainable methods of extraction/hydrolysis/purification to produce value-added products from the agro-industrial by-product of dragon fruit processing.
