  • The effect of sucrose, aspartame, acesulfame-K and blended aspartame/acesulfame-K on orange and strawberry flavor in model solutions

    Creator:
    Wiseman, Jennifer Jo
    Abstract:
    The effect of sweeteners on fruit flavor perception was studied through the use of fruitiness power functions for unsweetened and sweetened model systems. In the first part of the study, two isosweet concentrations of aspartame and sucrose were determined and combined with five concentrations of orange and strawberry flavorants. Fruitiness...

  • Factors affecting the antimicrobial activity of vitamin K₅

    Creator:
    Merrifield, Larry Stanford
    Abstract:
    Vitamin K₅, 4-amino-2-methyl-1-naphthol hydrochloride, a water soluble analog of vitamin K has been shown to possess an antimicrobial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preservative, and it was the purpose of this study to...

  • Mode of action of vitamin K on saccharomyces cerevisiae

    Creator:
    Rasulpuri, Muhammad Latif
    Abstract:
    Compounds belonging to the vitamin K family possess anti-hemorrhagic property, and are used in treating patients suffering from hypoprothrombinemia and obstructive jaundice. Some of these compounds also exhibit marked antimicrobial activity toward various microorganisms. Vitamin K₅, 4-amino-2-methyl- 1-naphthol hydrochloride, a water-soluble analog of vitamin K has been shown to possess...

  • Application of ozone as a disinfectant for commercially processed seafood

    Creator:
    Hansen, Jenny K.
    Abstract:
    Pacific oysters (Crassostrea gigas), Alaska pink salmon (Oncorynchus gorbuscha) roe and chum salmon (Oncorynchus keta) fillets were treated with aqueous ozone in both pilot plant and commercial settings to determine its effect on shelf-life and microbial changes. The microbial quality was analyzed by conducting pyschrotrophic and coliform plate counts on...

  • Characterization of Pacific whiting proteinase P-II and partial cloning of cathepsins L and K cDNA from rainbow trout liver

    Creator:
    Nickel, Xianbin F.
    Abstract:
    Proteinase P-II purified from parasitized Pacific whiting muscle was previously identified to be one form of cathepsin L. It appeared to be present in three isozymatic forms on non-denaturing PAGE gel stained for activity. Its autolytic degradation was observed on SDS-PAGE gel under its optimum condition, 55°C and pH 5.5,...

  • Lipid-protein interactions : autoxidation studies involving freeze-dried methyl linolenate-gelatin foams

    Creator:
    Wehr, H. Michael and Sinnhuber, Russell O.
    Abstract:
    Studies involving freeze-dried methyl linolenate-gelatin foams indicate that the extent of lipid-protein interaction corresponds to the degree of autoxidation of the lipid fraction. It appears that approximately 11% of the malonaldehyde as defined by the 2-thiobarbituric acid test is firmly bound to the protein. The induction period of autoxidation is...

  • The role of solvent extraction in the chemical characterization of corn stover feedstock

    Creator:
    Thammasouk, Khamphet
    Abstract:
    The consequences of extracting com stover feedstock with either 95% ethanol or hot water prior to the chemical analysis of the macrocomponents of that feedstock have been determined. Reports by others have recommended the removal of extraneous substance by solvent extraction prior to chemical analyses (Browning, 1967; TAPPI, 1988). The...

  • Influence of extractives on the chemical analysis of switchgrass

    Creator:
    Tandjo, Djuhartini
    Abstract:
    This thesis summarizes an investigation into the need for removing extractives from herbaceous biomass feedstocks prior to their chemical characterization. Switchgrass (Panicum virgatum), was used in this study as a representative herbaceous biomass feedstock. The influence of extractives on the chemical analysis of switchgrass was done by comparing the composition...

  • Quantitative polysaccharide analysis of lignocellulosic biomass

    Creator:
    Fenske, John J.
    Abstract:
    Lignocellulosic biomass is a potential source of fermentable sugars such as glucose. Enzymatic hydrolysis of cellulose is a viable method of solubilizing the glucose from biomass, but the cellulose fraction of native lignocellulosic material is shielded from enzymatic attack by the lignin-hemicellulose matrix surrounding it. Pretreating lignocellulosic biomass with dilute...

    Liaw, Ean-Tun
    Abstract:
    The influence of substrate and enzyme concentration on the rate of saccharification of two defined, insoluble, cellulose substrates, Avicel and Solka-Floc, by the cellulase enzyme system of Trichoderma viride has been evaluated. Assays utilized enzyme concentrations ranging from 0.014 to 0.056 filter paper unit per mL and substrate concentrations up...
