Abstract: Seasonal changes of biochemical composition of caramote shrimp head (CSH) and common cuttlefish viscera (CCV) were investigated.The effect of chilled storage (5°C) of these by-products during 21 days on the physicochemical quality indicators was evaluated for every season to assess a suitable storage period.All biochemical components varied significantly (P<0.05)overall season for both types of by-products except moisture and chitin contents, which remained constant in CSH (79.77±0.33%and 8.33±1.11%respectively).CCV and CSH by-products were a main source of proteins (28.37±5.44%and 20.37±5.77%respectively on dry weight basis (d.w.b)) and ash (23.60±4.18%and 28.28±2.32%respectively d.w.b).Principal component analyses (PCA) proved that CSH could be upgraded to obtain a rich product in minerals and chitin components at any time regardless the season.CCV collected in spring and summer could be assimilated as a homogenous group rich in protein and lipid.The chilled storage CCV and CSH during 21 days showed significant (P<0.05)variations of some physicochemical indicators and according to PCA, by-products might be stored just for few days (not more than a week) as proteolysis and lipolysis increased from the first week.
