A STATISTICAL STUDY IN FROZEN ON ·WEIGHT PRAWNS LOSS

Abstract

This paper deals with an extensive study conducted to
estimate the extent of weight loss in frozen prawns. The
weight Joss varied from 7 to 12% in peeled and deveined (PD),
5 to 7% in headless (HL) and about 7% in cooked and
peeled (CP) prawns from the date of processing to the date
of inspection, normally within two weeks. To compensate the
weight loss nearly 11% of excess material is being added
with every frozen block resulting in an average annual loss of
Rs. 2.68 crores in foreign exchange. The relevant data pertain
to the period 1971 to 1973 and the annual average loss was
estimated for the ten years ending 1973.
