  • Development of analytical methodology for verification of authenticity of apple juice

    Creator:
    Lee, Hyoung S.
    Abstract:
    Apples growing in New Zealand, Argentina, Mexico, Michigan and Washington were used to provide the compositional data and to develop the analytical procedures for the use in verification of authenticity of apple juices. High Performance Liquid Chromatography (HPLC) techniques were applied for glucose, fructose, sucrose, sorbitol, malic, citric, quinic, shikimic,...

  • Effect of polyphosphate on microbial characteristics of seafoods

    Creator:
    Petchsing, Urairatana
    Abstract:
    Effect of 6.0% polyphosphate treatment on microbial growth and composition of microbial flora of three representative seafoods were investigated. Polyphosphate treatment washed off microorganisms by 1 log in peeled shrimp (10⁷ to 10⁶ and 10⁶ to 10⁵) and cooked crab meat (10⁶ to 10⁵) and by 2 logs in red...

  • Characterization of Arthrobacter species isolated from marine and seafood sources

    Creator:
    McKenzie, Stephen M.
    Abstract:
    Forty Arthrobacter species isolated from Pacific and Atlantic fishery sources were examined to determine their significance in seafood. All strains were able to utilize inorganic nitrogen as the sole nitrogen source and grew in the absence of vitamins or growth factors. In addition, 78% grew on a medium containing only...

  • Microbial flora of Pacific oysters (Crassostrea gigas) subjected to UV-irradiated seawater

    Creator:
    Vasconcelos, George Joseph
    Abstract:
    The microbial composition of Pacific oysters (Crassostrea gigas) subjected to UV-treated seawater was determined by quantitative and qualitative means. A total of 2,779 microorganisms were identified from seawater and oysters during a 72 hour sampling period employing a computer assisted replica-plating technique. UV treatment effectively eliminated coliforms and Pseudomonas Type...

  • Dimethyl disulfide produced in sterile fish muscle by Pseudomonas putrefaciens

    Creator:
    Rhee, Kie Ho
    Abstract:
    Sterile fish muscle homogenate was prepared from the individually line caught black rockfish (Sebastes melanops) and inoculated with the pure culture of Pseudomonas putrefaciens strain 17. The inoculated homogenate was incubated at 5°C and the growth and production of volatile sulfur compounds determined by a combined gas-liquid chromatography and mass...

  • Nutritional and biochemical characterization of Moraxella species isolated from fishery sources

    Creator:
    Vernon, Stephen M.
    Abstract:
    One hundred and fourteen strains of Moraxella species isolated from marine fishery sources were investigated to determine the cause of this organism's predominance in seafood. The nutritional requirements, effect of pH, NaCl concentration, and temperature on growth, utilization of carbohydrates, protein, and lipid, resistance to 12 antibiotics, sensitivity to phenethyl...

  • Adhesive property of bacteria and its relationship to microbial spoilage of shrimp

    Creator:
    Smith, John B.
    Abstract:
    Pacific shrimp (Pandalus jordani) was washed repeatedly and the eluted bacteria were enumerated and identified. Selected isolates were tested for their adhesive properties. Washing reduced the microbial load by 3.84 to 42.04%. The bacteria which most resisted wash-off were Staphylococcus and Pseudomonas spp. The easiest to wash off was Flavobacterium...

  • Influence of commensal microorganisms on Clostridium botulinum type E.

    Creator:
    Patrick, Lui-sun Kwan
    Abstract:
    Achromobacter A43 produced a compound inhibitory to the outgrowth of Clostridium botulinum type E spores. The inhibitor could be produced in various laboratory media and the outgrowth of germinated spores was completely inhibited by 1/10th dilution of the A43 spent medium. Germination was not affected. The spores lost refractility in...

    Creator:
    Shiflett, Maureen Adele
    Abstract:
    The storage life at 43°F of ground dover sole fillets (Microstomas pacificus) was determined microbiologically after treatment with ionizing radiation and antimicrobial agents. Sodium benzoate, potassium sorbate and the sodium salts of the methyl and propyl esters of parahydroxybenzoic acid (MPB and PPB) all approximately doubled the refrigerated storage life...
