Chemical changes and shelf life of surimi of Carassius auratus (Carassius carassius gibelio) during storage at super chilling and freezing temperatures

Production of Surimi from low value fish is a method recommended to increase fish consumption nowadays. In this study, Carassius auratus gibelio was used to produce surimi. Experimental treatments were surimi stored at freezing temperature (-18˚C) (group 1) and surimi maintained at super chilling temperature (-3˚C) (group 2). The experiment lasted 60 days and approximate composition (moisture, protein, fat, ash and pH), chemical spoilage were examined and oxidation tests including total base volatile nitrogen (TVB-N) and Tiubarbutic acid (TBA) were carried out periodically. According to the statistical values of fat, pH, TVB-N and TBA were significantly higher in treatment 2 in comparison to treatment 1 during the maintenance period (p
