| Sumario: | The industrial processing of fish demands high usage of water and its main drawback is the production of effluents highin Chemical Oxygen Demand (COD). Surimi production from skipjack (K. pelamis) has not been reported and neither theseparation and recovery of its sarcoplasmic proteins from the wash-water. The aim of this research was to find a simpleprocess to recover solids and protein, using pH (2.5, 3.5, 4.5, 5.5, 6.5 or 9.5) and temperature (4, 25 or 90°C) combinations.The best processing conditions for protein precipitation were 4°C and pH 4.5, 5.5 or 6.5, with protein recoveries of about94% and purities of 92%. This protein recovery represented an average of 60% of the protein that was originally present inthe skipjack flesh, and around 50% of the initial solids. The essential amino acid profile for the best treatments exceededthe requirements for children or infants. The proposed process can contribute to 1) improve the economics of processingfacilities and 2) produce isolates with high protein quality. |
