The nutritional value and safety of various commercial FPC for human consumption was studied with rats. Although we found evidence that certain factor(s) depressed the nutritional quality of DCE-FPC, the presence of specific toxicants as causative agents of depressed growth could not be demonstrated. It appears that the method of fish processing and solvent extraction can have profound effects on the nutritional quality of FPC. Isopropanol extraction of fish resulted in a more nutritious FPC than DCE extraction. Further processing of DCE-FPC did not negate this nutritional inferiority. Species differences of fish are not the main reason for nutritional differences between IP- and DCE-extracted FPC (8, 17). These studies suggest that the more desirable FPC for human use would be that extracted with isopropanol.
