Cuttlefish viscera were stored at 4 or 25{\textdegree}C and sampled regularly over 4 months. Our results showed that total acid proteases and cathepsins were rapidly released to the extracellular medium due to the breakdown of lysosomes. Total alkaline protease activity increased 2 h after death due to the breakdown of zymogene vesicles. The same patterns were found with trypsin, chymotrypsin and $\alpha$-amylase activities. After 10 days of incubation, no endogenous enzymatic activity was found. After 50 days of storage, the TCA soluble protein levels decreased rapidly to approximately 30\% due to protein degradation and aggregation. After 10 days, the pH of viscera stored at 25{\textdegree}C was alkaline, whereas in the viscera stored at 4{\textdegree}C the pH increased more slowly. As significant reduction in the protein molecular weight due to autolysis, was also observed.}, issn = {0308-8146}, author = {Le Bihan, E and C{\'e}line Zatylny-Gaudin and Perrin, A and Sim{\'e}oni Koueta-Noussith{\'e}} }
