  • Porosity, surface area and enzymatic saccharification of microcrystalline cellulose

    Creator:
    Tantasucharit, Usicha
    Abstract:
    The research described in this thesis was aimed at understanding how particle size, porosity, and enzyme accessible surface area influence the rate of saccharification of microcrystalline cellulose. Microcrystalline cellulose (MCC) is a commonly used substrate for the study of cellulolytic enzymes. MCC preparations of different particle size are commercially available....

  • The role of molecular architecture in the hydration properties of brewers’ spent grain

    Creator:
    Yang, Jasmin S.
    Abstract:
    An emerging strategy to reducing food waste is converting food processing byproducts to nutritious and inexpensive food ingredients. A relevant food processing waste stream is brewers’ spent grain (BSG), the primary byproduct of beer production. BSG is a promising candidate as a food ingredient because of its high protein and...

  • 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...

  • Wheat lignin as a functional dietary fiber component

    Creator:
    Junyusen, Tiraporn
    Abstract:
    This dissertation has focused on lignin byproducts that result from the alkali processing of wheat straw. The first study evaluated the application of “standard” lignin quantification methods for summative analyses of alkali-based processes. Mass closure during NaOH processing at 25, 50, and 75°C of wheat straw was evaluated using the...

  • Analytical approach to the quantitative analysis of silicon in plants : its application to plant silica extraction

    Creator:
    Boone, Carmen E.
    Abstract:
    The literature available on the silica content of herbaceous biomass, and its relative mobility in leaching/extraction systems, includes studies that have employed several different methods for silica quantification. This makes comparison of the data difficult. The objective of this thesis research was to determine the quantitative relationships between the measured...

  • In Vitro fermentation of dietary cellulose by human fecal microorganisms

    Creator:
    Chang, Hung-pi
    Abstract:
    The purpose of the study was to set up an in vitro model of the colon which would permit the analysis of cellulose fermentation by human colonic microflora. Studies of the degradation of polysaccharides by colonic bacteria may help to explain the observed physiological consequences of consuming dietary fiber common...

  • Science and efficacy of mild sodium hydroxide treatments in enzyme-based wheat straw-to-glucose processing

    Creator:
    Sophonputtanaphoca, Supaporn
    Abstract:
    The work described in this dissertation focused on chemistry related to the use of aqueous sodium hydroxide as a treatment in the processing of wheat straw. A major emphasis was the comprehensive evaluation of straw component partitioning due to sodium hydroxide (NaOH) processing. This was evaluated over a range of...

  • Apparent inhibition of Pacific whiting surimi-associated protease by whey protein concentrate

    Creator:
    Piyachomkwan, Kuakoon
    Abstract:
    Surimi is a seafood product which is used to manufacture restructured products such as artificial crab and lobster. Surimi is produced from fish fillets by washing to remove sarcoplasmic proteins and increase the concentration of myofibrillar proteins, and mixing with cryoprotectants. A valuable attribute of surimi is its ability to...

  • The Role of Ascorbic Acid, β-Cyclodextrins, and Alternative Substrates in Dictating Rates of Polyphenol Oxidase-Catalyzed Browning in Potato-Based Reaction Mixtures

    Creator:
    Jiang, Shu
    Abstract:
    Enzymatic browning is a consequence of a series of reactions initiated by polyphenol oxidase (PPO)-catalyzed quinone formation. Unwanted browning negatively affects food quality and lowers consumer acceptability. Thus, there is general interest in strategies to control enzymatic browning. Cyclodextrins are cyclic glucan oligosaccharides that form inclusion complexes with a number...

  • Interactions of Trichoderma reesei exo-acting cellulases with p-aminophenyl 1-thio-β-D-cellobioside

    Creator:
    Piyachomkwan, Kuakoon
    Abstract:
    Cellulolytic enzymes capable of efficiently degrading crystalline cellulose are a complex mixture of endo- (endoglucanases) and exo-acting (cellobiohydrolases) enzymes. One approach to separating these enzymes is affinity chromatography. A new ligand, p-aminophenyl l-thio-β-D-cellobioside (APTC), is introduced for this purpose. The property of APTC in affinity chromatography is demonstrated using Trichoderma...
