Ultrafiltration for the recovery of proteins from surimi washing water

The aim of this study was to evaluate the efficiency ultrafiltration process (UF) in cleansing treatment tilapia surimi washing water and recovery components. After producing surimi, generated operations subjected UF a 30 kDa polyethersulfone membrane. Unfiltered waters permeate concentrate were analyzed for pH, total solids (TS) fixed (FS), proteins, lipids. chemical oxygen demand (COD) determined original permeate. dehydrated spray dryer amino acids carotenoids. showed significant decrease TS, proteins COD, indicating that efficient removing organic load from waters. percentage protein by 93.12% had all essential acids, being leucine (5.47%), lysine (6.49%), valine (3.59%), phenylalanine (3.68%) those with highest concentrations, also 0.67 mg/100 g application has proved be viable both valuable compounds decontamination water, contributing sustainability fish productive sector.
