Quality Indicators of Northern Shrimp (Pandalus borealis)

Qingzhu4.7 Water-holding capacity (WHC)The water-holding capacity of the shrimp is shown in Figure 12. It is evident that thewater-holding capacity of the shrimp after storage is lower than that for the raw shrimpbefore storage.94.093.0Water-holding capacity (%)92.091.090.089.088.087.0LIQ/-S-ICE/-LIQ/+ICE/+86.0-3 -2 -1 0 1 2 3 4 5 6 7Catch dayFigure 12: Changes of water-holding capacity of shrimp stored in differentconditions during the storage period.
