Identification of some soluble esterases of the carrot (Daucus carota I.)

Creator:: Carino, Lourminia Almeda
Abstract:: Substrate and inhibitor specificities have been used to classify esterases. The purpose of this work was to determine the substrate and inhibitor specificities of the esterases in an aquous extract of lyophilyzed carrots. Esterase activity was determined manometrically at 37°C. The optimum pH of the carrot esterases with several substrates...

Identification of some esterases of the green bean (Phaseolus vulgaris L.)

Creator:: Putnam, Teryl Beebe
Abstract:: This investigation was conducted to differentiate the esterases in a water extract of freeze-dried green beans on the basis of inhibitor and substrate specificities. An attempt was made to classify these esterases according to the criteria used for animal esterases. Activity of the esterases was measured manometrically using the Gilson...

Accumulation of dietary polychlorinated biphenyl by rainbow trout (Salmo gairdneri)

Creator:: Lieb, Andrew James
Abstract:: This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...

Analysis of flavor precursors in radish and radish color extracts

Creator:: Kucza, Myriam M.
Abstract:: Radish anthocyanin extract has potential as a natural colorant because of its pigment stability and attractive red hue. Presence of undesirable aroma compounds could limit its applications in foods. The pungent principle of radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG),...

Effect of proteolytic enzymes on emulsification characteristics of bovine skeletal muscle

Creator:: DuBois, Michael Wayne
Resource Type:: Masters Thesis
Full Text:: viscosity and emulsification capacity (EC) of the protein extracts were determined, the latter using a

Effect of berry integrity on proanthocyanidin extraction during wine production

Creator:: Cerpa-Calderon, Fiorella Karen
Abstract:: Proanthocyanidins are a grape-derived phenolic class of compound that provide wine with bitterness and astringency. Because of this, proanthocyanidins are considered to be essential components of wine quality. Proanthocyanidins are localized in the seed, skin and stem tissue of the grape berry and the composition of proanthocyanidins will vary depending...

Characterization of substrate-velocity relationships for the cellulase enzyme complex from Trichoderma viride

Creator:: 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...

Apple polyphenolics and their antioxidant properties : influence of cultivars, post-harvest storage, and 1-MCP treatment

Creator:: Widyasari, Maria Angela Artania
Abstract:: The distribution of total phenolics, antioxidant capacity, monomeric anthocyanin, and ascorbic acid contents in the peel and flesh of Red Delicious, Granny Smith, and Fuji apples during a six-month storage period were determined. In addition, the effect of 1-MCP (1-Methyl cyclopropene) on these parameters of the edible portion of apples...

Commercial application of high pressure processing for inactivating Vibrio parahaemolyticus in Pacific oysters (Crassostrea gigas)

Creator:: Ma, Lei
Abstract:: Vibrio parahaemolyticus is a Gram-negative, halophilic pathogen that occurs naturally in coastal and estuarine environments. This human pathogen is frequently isolated from a variety of seafood, particular oysters, and is the leading cause of gastroenteritis associated with seafood consumption. Several outbreaks of V. parahaemolyticus infections linked to consumption of raw...
