GEORGIANA I. BADEA, SIMONA C. LITESCU FILIPESCU, GABRIEL L. RADU, IOANA DIACONU EVALUATION OF THE EFFICACY OF VARIOUS GREEN EXTRACTION METHODS FOR HIGH VALORISATION OF VEGETAL ANTIOXIDANT SOURCES
This work presents the efficacy of various green extraction methods used to ensure the optimal amount of antioxidant compounds extracted from vegetal material. The new developed extraction procedures are easy-to-use and have a low implementation cost providing health-safe and high-quality extracts (products). The complete characterization of the obtained extracts was performed by a HPLC method (quantification of antioxidant compounds) and the ORAC method (efficacy assessment). These methodologies have high potential in by-products industry, where managing the residues is an important step in increasing the technological process economic efficiency and mitigation of environmental impact and, moreover, can by further extended to other types of raw materials.
