Bivalve species are important in Malaysian fisheries and aquaculture. Polymesoda
expansa, Meretrix meretrix and Glauconome virens have uncertain nutritional
composition and storage condition in case of poor sales or unable to cook immediately.
These bivalves are collected from local vendors, then stored shucked or unshucked in
-20, 2 and 25⁰C. Proximate value for moisture, ash and lipid were observed daily for
three days. The initial moisture, ash and lipid of these species were benchmarked
whereby for P. expansa it was 81.1, 12.8 and 5.8%; for M. meretrix it was 81.2, 12.6
and 3.3% and; for G. virens it was 80.3, 15.5 and 2.8%, respectively. Study shows
that mussels are better stored unshucked to retain moisture content. Ash can be
retained higher in -20⁰C and lipid content varies greatly among speciesand seasonal
by gonadal development. Fatty acid composition study is recommended along with
thawing condition with added parameters (protein and fibre).
