METHOD FOR QUALITY ASSESSMENT OF FISH, helminth infections

摘要

Method for evaluating fish quality infested by helminths comprising determining component concentrations of volatile organic substances in the extract obtained by steam distillation of bioassays with a gas chromatograph, characterized in that for bioassays using organs and muscle tissue of fish, which are ground to give the hood and placed in a gas chromatograph, and the results obtained for the total concentration of aldehydes and esters and by formation and accumulation of alcohols and ketones in the process of life helminths deteriorate lev els physicochemical characteristics of fish, determine their purity, exceeding the total concentration of aldehydes and esters with intensive invasion Anisakis simplex larvae and plerocercoids Ligulidae Ligula intestinalis fish, for example whiting, herring, anchovy, and - more than 20; pollock and capelin - more than 7 relative to the benchmark results, refer to substandard and sent to technical utilization for the production of fishmeal.
