Property Changes of Salt-seasoned Salmon Roe during Fermentation

In order to utilize chum salmon returned in the east coast of Korea, the changes in the properties of Yeonual-jeot (salted salmon roe) fermented at different temperatures were measured for obtaining the basic data for its commercial production. Moisture content of salted salmon roe was significantly lower than raw salmon roe, while other proximate components were in the reverse. pH was constant for 56 days fermentation at $5^{\circ}C$, but decreased with fermentation Reriod at 10 and $15^{\circ}C$. The contents of amino-nitrogen and VBN were almost in constant at $5^{\circ}C$ up to 28 days of fermentation, but increased very slowly at $10^{\circ}C$ and moderately at $15^{\circ}C$. TBA value, and the numbers of total viable cells and lactic acid bacteria increased over all fermentation periods, more at higher fermentation temperatures.
