dc.description.abstractTHE LYOPHILIZED STRAWBERRY ANTHOCYANINS WERE EXTRACTED USING A SUPERCRITICAL EXTRACTION (SE) PROCESS. THE EFFECT OF PULSED ELECTRIC FIELDS (PEF) AS PRETREATMENT AND THE INFLUENCE OF THE ADDITION OF ETHANOL AS A COSOLVENT ON THE PERCENTAGE OF EXTRACTION YIELD (EY) AND THE TOTAL ANTHOCYANIN CONCENTRATION (TAC) WERE ANALYZED. THE EFFECT OF PEF WAS EVALUATED AT 0.5 AND 1.0 KV/CM, WHILE THE EFFECT OF THE COSOLVENT WAS STUDIED IN MIXTURES OF SUPERCRITICAL CARBON DIOXIDE - ETHANOL (SCCO2 + ETHANOL) AT 1.6 AND 3.3% BY WEIGHT. THE BEST RESULTS (% EY = 0.506, TAC = 0.428 G /100 G OF LYOPHILIZED STRAWBERRY) WERE OBTAINED WITH A PEF PRETREATMENT OF 1.0 KV CM-1, 3.3%WT. ETHANOL AT 200 BAR AND 333.15 K. THE EXPERIMENTAL RESULTS OF SOLUBILITY WERE SUITABLY ADJUSTED WITH THE KUMAR AND JOHNSTON MODEL. THE MAXIMUM SOLUBILITY (0.114 G/100 G OF SOLVENT MIXTURE) WAS OBTAINED AT 300 BAR AND 313.15 K.
