Notes:
: This work evaluated the effect of caseinate-transglutaminase and fibrinogen-thrombin cold-set binding systems on physical, textural, and microstructural properties of restructured adductor muscles of 2 commercially important species of scallops found in Mexico, the Pacific calico scallop (catarina scallop; Argopecten ventricosus) and the giant lions-paw scallop (Nodipecten subnodosus). Proximate composition and surface pH was measured in raw materials. Color, water-holding capacity, and texture, including the Warner-Bratzler shear test and texture profile analysis were determined for restructured products and raw material. Results indicate that binders affected color in lions-paw scallops. Caseinate-transglutaminase did not affect color of restructured samples of either species. The effect of cold-set binding systems on the water-holding capacity was observed only for lions-paw scallops. In different ways, binders affected texture parameters except for gumminess and adhesiveness. Differences in microstructure of the binder matrices were observed. The caseinate-transglutaminase matrix exhibited a solid continuous phase and the fibrinogen-thrombin system exhibited a discontinuous matrix with different levels of aggregation of the material. Results indicated that, not only the restructuring system, but also the species influenced color, water-holding capacity, and texture of restructured products.
