The appearance and color of uncooked and cooked samples over
all treatments are depicted in Fig. 1. It is obvious that all cooked
shrimps treated with amino acid at any concentration (except
lysine at 2.0 g/100 ml) resulted to products with similar appearance
to STPP-treated sample. Shrinkage of fresh and control as well as
NaCl-sample treated shrimp could be observed.
