In this study, the effect of commercial additives viz. cafodos and altesa employed to treat Indian octopus (Cistopus indicus) was examined during chilled and frozen storage. Shelf lives of treated and untreated octopus in ice were 6 and 8 days, respectively in ice. Treated and untreated frozen octopus had a shelf life of 40 days. Autolytic and microbiological changes were not controlled by the additives, as evidenced through rapid reduction in non-protein nitrogen (NPN) and α-amino nitrogen (α-AN) compounds; as well as accumulation of water soluble ammoniacal nitrogen and total volatile base- nitrogen (TVB-N) compounds. Loss of texture and colour were the major quality defects noticed in treated octopus as a result of enhanced protein solubility. Therefore, the additives approved for use in octopus neither enhanced the shelf life nor improved the sensory quality.
