Abstract

Effects of blanching (95C for 30, 60 or 120 s) prior to freezing on physicochemical and functional properties of proteins from frozen prawns (Metapenaeus dobsoni) were investigated. Blanching increased the rate of drip loss during storage at -18C. Gel filtration indicated that blanching resulted in complete dissociation of proteins. Sedimentation velocity patterns of proteins extracted from blanched prawns showed a single peak with an s20,w value of 2.5S. Blanching reduced water absorption and fat absorption capacity, foam capacity, foam stability and emulsion properties of the proteins.
