Abstract

Antioxidants are molecules that have the capacity to inhibit oxidative reactions, which can result in deterioration of foods, nondurable goods and body cells. Therefore, the inhibition of oxidative reactions is of great interest in many industrial sectors, such as food, pharmaceutical, petrochemical, chemical and several industries related to human health. Polyphenols are substances that exhibit antioxidant capacity similar to synthetic antioxidants currently used in industries. Polyphenols have been extensively studied in recent years because of the possibility of obtaining these molecules from agro-industrial by-products. Sugarcane bagasse, a by-product derivated from ethanol and sugar process, is a lignocellulosic agro-industrial residue with high availability in Brazil, which can be employed for the production of second-generation ethanol and other value-added products. Due to the recalcitrant nature of lignocellulosic biomass, the pre-treatment is necessary to remove lignin, which turns the hemicellulose and cellulose available for subsequent enzymatic hydrolysis steps for biofuel production. Lignin is an amorphous macromolecule composed of phenylpropane units and represents above 20%-30% of the total lignocellulosic material. Its fragmentation generates phenolic compounds and polymers with different properties and functions of interest to several industrial sectors. Considering the global trend for replacement of non-renewable sources to renewable agro-industrial by-products, the use of antioxidants derived from lignin represents as a promising area of research. Here in this present proposal, we show preliminary results that report the antioxidant potential of lignin fragments extracted from sugarcane bagasse. Thus, this project aims to evaluate the antioxidant properties against reactive oxygen species (ROS) and nitrogen species (RNS) of the phenolic compounds present in lignin fractions derived from the sugarcane bagasse. The project also covers the fragmentation of lignin via chemical and enzymatic route, separation of lignin fragments by extraction with organic solvents; characterization of fractions obtained by mass spectrometry, infrared spectroscopy and nuclear magnetic resonance spectroscopy. The composition of the fractions will be correlated with antioxidant capacity against ROS and RNS through multivariate statistical analysis. In addition, we propose in this project the preparation of non-ionic emulsion based preparation with high antioxidant potential. This project will be developed at Brazilian Bioethanol Science and Technology Laboratory (CTBE) in partnership with the Department of Food Science, Faculty of Food Engineering in State University of Campinas.
