The State of Water in Frozen Fish

We have investigated the dielectric permittivity of fresh and sea water fish flesh as a function of temperature. The measured spectra are complex with many overlain interfacial processes. However, 2 distinct process related to water-protein complexes can be identified. One is hydration water around proteins. The second is a glass forming process of unknown origin. The paper will discuss it possible origin and if it could be linked to anti-freeze properties in the flesh of fish.
