This study examined the effects of different surimi-to-silver catfish ratios (0/100, 20/80, 40/60, 60/40, 80/20, and 100/0) and potato starch concentrations (3, 5, and 7%) on the properties of fish sausage. The surimi-to-catfish ratio affected the moisture, fat, protein, and ash content of the sausage; as well as cooking loss, greenness, lightness, and hardness. Different concentrations of potato starch affected carbohydrate content, springiness, and yellowness. The most acceptable formulation was the 40/60 surimi-to-catfish ratio with 7% potato starch. Vacuum-packed fish sausages from all formulations had low peroxide and 2-thiobarbituric acid (TBA) values during 12 days of refrigerated storage.
The heat inactivation of a mixture of alkaline proteinases from North Sea cod (Gadus morhua) viscera and bovine a-chymotrypsin were compared at 4O-6O0C, pH 8.0. Fish digestive proteinases were at least 10-fold less heat resistant than chymotrypsin mainly as a result of a lower apparent activation enthalpy (AH') for the thermoinactivation of the former proteinases.
This study aimed to determine the effects of 2-5 wash cycles and the addition of tetrasodium pyrophosphate (TSPP) (0 %, 0.05 Surimi% and 0.1 % w/w)-with or without the addition of 0.4 % calcium chloride (CaCl2)-on the physical properties such as texture, colour, expressible moisture and microstructure of Cobia (Rachycentron canadum) surimi gel. The highest breaking force (484.85 g) was obtained with the addition 0.1 % TSPP alone on the fifth wash. However, a combination of 0.1 and 0.4 % CaCl2 in surimi gels at wash cycle 5 resulted in the highest degree of whiteness (86.8 %), as well as total expressible moisture (2.785 %) and deformation (17.11 mm). The highest surimi gel strength (6,923 g.mm) was obtained after three wash cycles with the addition of 0.1 % TSPP +0.4 % CaCl2. The physical properties of Cobia fish surimi gels were affected by the number of wash cycles and treatments with TSPP and CaCl2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
