ABSTRACT
Very few studies have been reported in the literature showing the effect of processing on nutritional content of shellfish. Information published is incidental to other studies, often not giving details needed for proper interpretation. The first and the second table shown have been prepared using primarily review articles to indicate nutritional content of raw and processed edible portions, respectively. The remainder of the tables presented have been selected to show changes in composition due to a given processing of a specific shellfish. It must be pointed out that shellfish exhibit significant seasonal and harvest area variability in nutritional content. Significant differences in composition have also been detected among various body parts of Crustacea. Consequently, data of studies paying special attention to these factors are included.
