Study on Protein Recovery Process Optimization of Surimi Processing Wastewater

Abstract:

As to a large number of proteins from discharge wastewater of Surimi processing enterprises,A single factor experiment about the dosage、temperature、 time、 pH can be operated by selecting a flocculant.Then Design-Expert software is a experimental containing four factors and three levels.The result shows that:the optimal recovery process is adding the amount of ferric chloride 0.13 g/L,the flocculation temperature is 18.44 ℃,the time is 5 h,the pH is 5.44.At this point,recovery rate achieves to 89.94%.The method has the features with a high protein recoveries,the safety and health of the recovery protein,easy operation,low cost,etc.
