Anaerobic/aerobic pretreatment of blue crab (Callinectes sapidus) cooker wastewater
Wastewater from the pressure cooking of blue crabs presents a difficult treatment challenge. COD concentrations in the range of 15,000 to 30,000 mg/L are found in this wastewater, with TKN concentrations above 2,000 mg/L. Direct discharge of the wastewater, which is currently allowed, adds …

A technology analysis of the U.S. Atlantic blue crab (Callinectes sapidus) processing industry
The dehydration rates of crabs during low temperature storage and various cooking processes were determined. Season, cooking time, and cooking method significantly affected the weight loss of crabs. The thermal energy (F250 ) crabs received during a commercial cooking process was evaluated by …

Detection, activity and resistance to thermal inactivation of peroxidase in the blue crab (Callinectes sapidus)
… claw and flake meat of both male and female blue crabs was determined spectrophotometrically. Activity was greatest in the flake and least in the claw. Male crabs usually exhibited a greater initial activity (λ 0D 460/min) than did females of equal size. The larger the crab for a given sex, …

Feasibility study for packaging and pasteurizing meat of the blue crab, Callinectes sapidus, in retort pouches
… was to determine the feasibility of pasteurizing crabmeat in retort pouches compared to cans. Retort pouches and cans were packed with various amounts of crabmeat, pasteurized to an internal temperature of 185°F (85°C) for 1 min, and subsequently cooled. The criteria for evaluation were total …

The Effect of Thermal Processing Schedules and Unit Operations on the Quality of Blue Crab (Callinectes sapidus) Meat
… habits on the microbiological quality of blue crab (Callinectes sapidus) meat were determined in a commercial crab processing facility. Thermal processing was evaluated at 5, 7, and 8 minutes at 250ï °F for the destruction of microorganisms, including Listeria monocytogenes. F-values …

The presence and growth characteristics of Listeria monocytogenes in blue crab (Callinectes sapidus) meat and the effectiveness of microwave energy in a pasteurization process
… levels of Listeria monocytogenes in fresh blue crab (Callinectes sapidus) meat and its behavior in the presence of L. innocua and competing microflora were determined. An attempt was made to develop a process using microwave energy to destroy, or significantly decrease, naturally occurring …

Recruitment of Blue Crab, <i>Callinectes sapidus,</i> Postlarvae to the Back-Barrier Lagoons of Virginia's Eastern Shore
<p>Most research on the early life history of the blue crab, Callinectes sapidus, has been conducted in large partially stratified estuaries such as the Chesapeake Bay. In contrast, little is known about the recruitment dynamics or habitat requirements of blue crab postlarvae (megalopae) in shallow …
