The ability of salmon plasma protein (SPP) obtained from Chinook salmon at the Klaskanine Fish Hatchery (Astoria, OR) to inhibit protease enzymes found in Pacific whiting (PW) surimi and salmon mince as well as the effect of SPP on the gelation properties of PW surimi under various heating conditions was...
The effects of the residual salt of surimi on biochemical and physical properties as affected by various freeze and thaw cycles were examined. Fresh Alaska pollock (Theragra chalcogramma) surimi was mixed with 4.0% sugar, and 5.0% sorbitol, along with eight combinations of salt (0.4, 0.6, 0.8, and 1.0 % NaCl)...
Pacific whiting and its by-products were good raw materials for high quality fish sauce production. Heat stable and salt activated enzymes were responsible for autolytic activity in Pacific whiting and by-products. According to temperature profiles of raw materials at various salt concentrations, two fermentation temperatures, 35°C and 50°C, were selected...
The major portion of Pacific whiting (PW) is commercialized in the form of frozen surimi. Alternative products for PW were investigated focusing on fresh surimi and texturized meat from PW mince. Fresh surimi is made without additives and kept refrigerated instead of frozen. Texturized meat is a meat-like product made...
The effects of freeze-drying and flake freezing of surimi on biochemical and physical properties as affected by various storage conditions were examined. Using three cooking parameters shear stress and strain values were evaluated to measure gelation properties of surimi gels. Stress values increased up to 3 months and then decreased...
In surimi manufacturing, less than 25% of the total weight of the fish is utilized. This research focused on meat recovery from fish frames, the residual portion of the fish after filleting headed and gutted fish. A new technology, the water jet deboning (WJD) system, was tested. The WJD system...
Gadoid fish, like Alaska pollock and Pacific whiting, have a high level of trimethylamine-N-oxide demethylase (TMAOase) that catalyzes the breakdown of trimethylamine-N-oxide (TMAO) to formaldehyde (FA) and dimethylamine (DMA) even during frozen storage. FA reacts with amino acid residues to promote covalent cross-links in the formation of inter- and intramolecular...
Fish ball is an extruded surimi-based product that is popular among Asian communities. In the manufacturing of fish ball, optimum floatation is extremely important for maximal production. Factors affecting floatation of fish ball in water were investigated. The density of threadfin bream surimi paste significantly decreased (P<O.05) as moisture content...
Effects of thermal and electron beam (e-beam) processing on microbial inactivation and physichochemical properties of surimi and surimi seafood were investigated. Thermal-death-time (TDT) concept was used to model Staphylococcus aureus inactivation by heat and e-beam. Gurney-Lurie charts were used to estimate temperature during thermal processing of surimi seafood. Dose mapping...
Feasibility of ohmic heating to overcome gel-weakening in Pacific whiting surimi
was investigated. An ohmic heating apparatus was developed using two rhodium-coated
stainless steel electrodes inside a polyvinyl chloride (PVC) tube, a variable transformer,
and voltage and current transducers. Rapid heating associated with the ohmic process
quickly inactivated endogenous proteinase(s),...
