Transfer Rate of Saccharides in Fish Flesh

Abstract

Transfer rate of saccharose in tuna flesh was measured as a part of studies on mass transfer of several kind of substances in fish flesh. As a result, it was expressed isotropically by diffusion mechanism like as those on glucose and salts reported in our previous papers. The relationships between diffusivities in fish flesh and in water were approximated by two straight lines, for salts of uni-valent cations and bi-valent cations, on a log-log plot. Glucose and saccharose were correlated closely to the latter line. From these results, equations expressing the relation between apparent diffusivities in fish flesh and in water were proposed.
