The use of the cryoprotectant sodium tripolyphosphate as a possible method to minimize weight loss in frozen prawns

Abstract

A 5% wI I solution of foad grade Sodium Trj~olyph~sphate, N~P:sO.1QJ. 6HzO was used as a dip solution to tre~t partially processed prawns prio~ to freezing. The f t'ozen rrp~n~ ~~re then examined to determine whether dip treatment significantly ~ffe~ted the w~i3ht loss (dr~p lass) in the frozen pr""""",s, rne.!aslJ ""erl I as raw and cooKed )ield. The influence of dip +~~~+~~~t ~~ th~ ~~3a~aleptic and mic,'"ob...c...cgiLal qualities of r~~w~~ w~.e also studied.
