Surimi is a separated fish flesh, water washed, mixed with cryoprotectants, frozen and frozen stored. The purpose of adding cryoprotectants is to minimise freeze denaturation rate in myofibrillar proteins during frozen storage. Sucrose and sorbitol are widely used cryoprotectants in commercial surimi production. As sucrose and sorbitol impart sweetish taste to end product, many alternate cryoprotectants are being attempted in surimi production. Starch from different sources could be one of the alternatives because of it's hydrophilic nature. In the present investigation fresh Indian oil sardine (Sardinella longiceps) have been used to prepare surimi. The water washing of mince was carried out for five times with fish to water ratio being 1:3. The dewatering of the washed mince was achieved by basket centrifuge. tapioca Starch at 2, 5 and 9% (W/W) was mixed separately to the dewatered mince and frozen at -35°C and stored at -20°C. Surimi without starch served as control. The frozen sample was drawn periodically and assessed for hydrodynamic and rheological properties. Following are the salient features of the present investigation. [ABSTRACT FROM AUTHOR]

Water washing of sardine meat for five cycles reduced the fat content by 80% and non protein nitrogen content reduces by 72%. The washed meat showed higher gel forming ability as indicated by gel strength values and dynamic viscoelastic behaviour. [ABSTRACT FROM AUTHOR]
