I.3. Hot smoking
The temperature used for hot smoking can vary from 65° C to
temperatures as high as 120° C. The fish are partially or wholly cooked
within a short time (2-4 hours). In the initial stages of hot smoking, it is
important that the fish are not subjected to excessively high temperatures as
this will result in the flesh being cooked and breaking up prior to the
formation of a surface skin which will hold it together. If hot smoking is
continued over an extended period, drying will take place, thus resulting in
smoke dried products with an extended storage life. Smoke drying
temperatures should be between those used for cold and hot smoking. A range
between 45 and 70° C can be suggested although temperatures well above this
are often
used.
