tMembrane technology is an attractive technique for purification of bromelain enzyme from pineapple. In this study, the feasibility of bromelain purification from pineapple’s crudewaste mixture (CWM) extract was investigated using a two-stage ceramic ultrafiltration (UF)scheme involving 75 kDa and followed by 10 kDa tubular ceramic membranes. Both UF stageswere performed at specific processing conditions and determination on the permeate fluxvalues and the extract properties of each UF stage were conducted. Observations were alsoemployed at different feed pH and processing temperatures in both UF stages for processingoptimization. Results showed the proposed technique managed to retain 96.8% enzymerecovery in the UF stage 1 and increase the bromelain purity up to 2.5-fold, which is withinthe targeted purity requirement, in the UF stage 2. The permeate flux values for UF stages 1and 2 were 11.6 and 6.2 kg/m2h, respectively. Higher VRF of the process in UF stage 2 leadsto higher enzyme purity, thus the process can be adjusted depending on the enzyme finalapplications. For a better flux behaviour of the process and preservation of the bromelainenzyme during the process, this study suggests to adjust the feed pH to 7.0 and performingthe process at room temperature (∼20◦C).
