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...
For years, the Oregon fishing industry has argued that the lack of coastal cold storage designed to handle seafood has severely limited the opportunity to develop value-added products and retain seafood industry employment. Once landed, the majority of Oregon seafood spends little time on the coast, and a large portion...
The effect of washing machine separated rockfish flesh on
composition, quality and desirability was investigated.
Washing machine separated rockfish flesh resulted in a
36.88% loss of solids. The greatest reductions were found in the ash
(80.32%) and lipid (65.13%) levels in the washed flesh. Most of the
sarcoplasmic proteins were...
Staphylococcus aureus is a human pathogen capable of producing enterotoxins causing staphylococcal food poisoning, one of the most economically important foodborne diseases in the U.S. This pathogen may be introduced to pre-cooked tuna meat used for the production of canned tuna because significant manual handling occurs after cooking of the...
Freezing is one of the important technologies for preservation of foods.
In this project, using surimi as a food model, thermophysical properties of frozen
foods were evaluated and the freezing process was simulated using a finite
element package.
To measure temperature-dependent thermal conductivity, a line-source
probe system was used. Effects...
The biochemical and organoleptic changes that took place in
raw whole Pacific shrimp and in the cooked meat during eight days
of iced storage were investigated.
A steady increase of both microbial numbers on the raw shrimp
and pH in the raw shrimp and cooked meat was observed.
The levels...
A method was devised and tested for rapid and quantitative
identification of microbial flora in fresh seafoods. The rapid
identification of large numbers of isolates was made possible by
(1) a simplified identification scheme established by reference
culture studies and from the known reactions of microorganisms
reported in the literature,...
The effects of ambient temperature storage on the chemical
and nutritional characteristics of phosphoric and sorbic acid-stabilized
fish autolysates were determined. Variations in sample
composition due to autolysis, deboning, and acidification were also
evaluated.
Autolysates of English sole (Parophrys vetulus), true cod
(Gadus macrocephalus), Dover sole (Microstomus pacificus), and
orange...
The effect of salt (0, 0.9, 1.7, 2.5%) and pH (range 4
to 10) on surimi gels made from Pacific Whiting (Merluccius
productus) was investigated. Gel-forming ability was measured
by the torsion test. In general, surimi gels
increased in gel strength with increased pH. Breaking shear
stress increased to a...
Limited resource catfish producers are seeking ways to enhance economic and financial profitability of their aquaculture enterprises. One of the recommended methods to increase profitability is to sell value added smoked catfish at niche markets. Development of value-added smoked catfish is a potential cottage industry for limited resource catfish farmers...
