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 characteristics of Northern squawfish
(Ptychocheilus oregonensis) and the feasibility of utilization
of this species for human consumption were investigated. In
the first experimental phase, the iced storage characteristics
of squawfish were determined. Quality changes were monitored
over 24 days of storage by chemical, physical, microbiological
and sensorial methods of...
Anserine and carnosine are water-soluble dipeptides that have antioxidant
properties and are found in the skeletal muscle of mammals and fishes. These
dipeptides are removed through the washing process in surimi production. The
objective of this research was to determine the concentration of anserine and
carnosine in surimi wash water...
Pacific whiting, with a maximum sustainable yield between 150,000 and 250,000 metric tons, is the largest stock of fish found off Oregon. The majority of the fish are processed into surimi. Hundreds of variables could potentially affect surimi quality (gel strength). Alternative harvesting and processing input combinations, as well as...
The effects of various pressure treatments (OK, 30K, 60K, 75K psig) and packing medium (water or cocktail sauce) on shucked oysters were investigated. The pH, moisture content, microbiological tests (including aerobic plate count (APC) and anaerobic plate count (ANPC)), enzyme assays (i.e. α-amylase, β-amylase, lipase and peroxidase activities) were conducted...
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...
Pacific whiting (Merluccius productus) is the most abundant
groundfish species off the California, Oregon and Washington Coasts.
The fish are mainly used as a raw material for the production of surimi.
However, it is not economically wise to depend only on one product.
There is a need to diversify the...
