Abstract A thermal treatment for the prevention of insect infestation in dry fish is described.
ยท The treatment was carried out in a tunnel drier/solar tent drier maintained between 55-
65'C. The optimum time of exposure for thin varieties of dry fish was 60 min and 90 min
for thick fish. The thermally treated products were packed in polythene bags after cooling.
Untreated control had an insect-free shelf life of 1-2 months, whereas the heat-treated
controls remained insect-free for 4 months. Refined and preservative treated fish remained
insect-free for more than 6 months, while heat treatment further extended the shelf life to
more than 12 months.
