The concentrations of protein in the effluents from Alaska pollack frlzen surimi manufacturing factories and their flow rates were measured to estimate fhe amount of protein resources lost in the effluent. Samples for protein concentration measurement were taken at three sites through the flow line of the effluent; the No.1 and the No.2 sites were the first and the second stage of the washing-out process and the No 3 site was the pit for effluent treatment. By use of the data at the No. 3 site, the total amount of protein lost in the effluent was estimated to be as much as 30-60 percent of that of the frozen surimi products. Protein recovery of the effluent at the No.1 site and thay of No.2 site would be worthwhile, since these effluents are rich in protein. It was found that their total protein concentrations were in the rang of 2-8 g/l, about 80 percent of which of which was water soluble protein.
