Processing of fish protein concentrate by using saline concentrates and study some of its quality

Abstract The AOAC official method, 24.029–24.035, for the determination of fluorine in foods was modified slightly to o btain quantitative recoveries of fluorine from samples of fish protein concentrate (FPC). The most important alterations include the use of steam distillation, the addition of finely ground silica sand in the distillation, a decrease in the distillation temperature, and the utilization of direct titration. Recoveries of fluoride added to FPC before ashing, using this modified method, averaged 96.0 ± 3.0%. Our results are in agreement with those of several other analysts who used a variety of methods.

Proteinaceous Food

The potential reclamation of mercury contaminated proteinaceous food by an extraction procedure such as employed in making fish protein concentrate was investigated. The addition of hydrochloric acid to the isopropanol extractant was found to give removals as high as 93% from dry swordfish protein concentrate. The normal Halifax isopropanol extraction process did not effect any significant removal of the mercury.Preliminary studies of the variables indicated acid concentration, kind of alcohol (ethanol and isopropanol), alcohol concentration, extractant volume, and number of extractions were important in the extraction.
