Influence of refrigerated storage on quality of fatty raw material by the example of Pacific herring has been investigated. After freezing and during storage at different temperatures in samples of frozen Pacific herring wedetermined the microbiological parameters, the content of toxic compounds, changes of proteins and accumulation of products of lipids oxidation. In parallel it was determined the quality of frozen herring by method of biotesting using infusorian Tetrachymena pyriformis. It has been established, that during storage of frozen Pacific herring the loss quality of fish raw material takes plase. Results of biotesting completely correlate with the data of chemical analysis under the estimation of fish raw material quality of refrigerated storage.
