STANDARDIZATION OF POLYPHOSP 1k, TREAT NT FOR TINY PRAWNS (PARAPENAEOPSIS STYLIFERA) WITH SPECIAL FERENCE TO ITS REHYD TION CAPACITY ORGANOLE IC QUALITY*

Abstract

In the present study, an attempt was made to explore the benefits of
polyphosphate for enhancement of dried prawn (Parapenaeopsis stylifera)
quality commercially known as "sode" in Maharashtra coast. Dip treatment
in polyphosphate solution at different concentrations (viz., 3, 5, 7 and 10%)
was given to pealed and undeveined P. stylifera for different durations (viz.,
1, 2, 3, 4 and 5 min). Treated prawns were dried and subjected to rehydration
capacity test and organoleptic evaluation. Among the different treatments,
rehydration capacity was found to increase with the increased duration and
concentration of treatment. Tiny prawns treated with sodium tripolyphosphate
solution at the rate of 5% concentration for 5 minutes showed
an increase in pH from acidic to alkaline, and had better quality with respect
to rehydration capacity and textural attributes as compared to other
concentrations and durations of polyphosphate treatment.
