RESUMO

Bromelain is a set of proteolitics enzymes found in vegetables of the Bromeliaceae family, from which pineapple is known more. Bromelain has several uses, alI based on its proteolitics activity. There are the necessity to develop new processes for purification and concentration of these composites, the liquid-liquid extraction by reversed micelles reveals as one attractive technique, therefore it has had the specific capacity of getting solub1e biomolecules of an aqueous solution, as the crude extract of the pineapple. This is a study on the recovery of bromelain through liquid-liquid extraction by reversed micelles. Three distinct micelar systems formed from BDBAC (cationic surfactant), AOT (anionic surfactant) and CTAB (cationic surfactant) were employed. Statistical designs were used to select the most significant variables for each process. Surface response methodology was used to quantify the levels of the significant variables. In this work systematic studies are performed on the influence that certain parameters have on the recovery of bromelain through liquid-liquid extraction by reversed micelles, concerning forward and back extration. The goal is the system mathematical characterization and otimization
