Influence of ozone on shelf-life and quality of silvergrey rockfish (Sebastes brevispinis) Prahst, Armin-Wilhelm
Abstract
Ozone treatments of the chilled water surrounding fish during storage affects microbial and sensory properties of the stored product. In the first part of the study a better understanding of the effect of ozone on the microbial and sensory properties of freshly caught Silvergrey Rockfish (SebasLes brevispinis) was obtained. In the second part of the study, a method to quantify the inactivation of various typical fishspoilage microorganisms by ozone was developed. A survey examining the unloading process of fishing boats indicated that the unloading process did not contribute to an increase in microorganisms on the skin of tested fish samples. Sensory properties of the fish were not significantly improved by ozone treatment during an experiment simulating storage conditions on British Columbia fishing boats. The only significant difference (p

Ozone treatments of the chilled water surrounding fish
during storage affects microbial and sensory properties of the
stored product. In the first part of the study a better
understanding of the effect of ozone on the microbial and sensory
properties of freshly caught Silvergrey Rockfish (SebasLes
brevispinis) was obtained. In the second part of the study, a
method to quantify the inactivation of various typical fishspoilage

A survey examining the unloading process of fishing boats
indicated that the unloading process did not contribute to an
increase in microorganisms on the skin of tested fish samples.
Sensory properties of the fish were not significantly improved by
