Investigation of film forming properties of beta-chitosan from jumbo squid pens (Dosidicus gigas) and improvement of water solubility of beta-chitosan, Investigation of film forming properties of β-chitosan from jumbo squid pens (Dosidicus gigas) and improvement of water solubility of β-chitosan

Creator:: Chen, Jeremy L.
Abstract:: The objectives of this project were to investigate the critical factors impacting the physicochemical and antibacterial properties of β-chitosan based films derived from jumbo squid (Dosidicus gigas) pens, and to evaluate the feasibility of improving water solubility of β-chitosan through Maillard reaction. The studies examined the effect of molecular weight...

The impact of Saccharomyces and non-Saccharomyces yeast on the aroma and flavor of Vitis vinifera L. cv. 'Pinot Noir' wine

Creator:: Takush, David G.
Abstract:: The impact of yeast on the aroma and flavor of Vitis vinifera L. cv. 'Pinot Noir' wine was investigated. Due to the presence of naturally occurring yeast and bacteria on grapes and wine equipment, and the influence these microorganisms have on wine, a means of eliminating microorganisms from grape must...

Effects of Vineyard Managements on Grape and Wine Quality in Response to Grapevine Red Blotch Disease

Creator:: Huang, Ling
Abstract:: Grapevine red blotch virus (GRBV) is a single-stranded DNA virus that causes grapevine red blotch disease (GRBD). Symptoms of GRBD include red discoloring of leaf margins and red veins on the underside of the leaves. GRBD affects the plant's metabolism and photosynthetic pathways, and disrupts carbon translocation and chlorophyll concentrations....

Microbiological control of food spoilage and pathogenic microorganisms in refrigerated foods

Creator:: Al-Zoreky, Nageb
Abstract:: Microgard, a commercially-available pasteurized fermented milk, was found inhibitory to gram negative bacteria such as Pseudomonas putida, some well-known foodborne pathogens (e.g. Salmonella, Yersinia and Aeromonas) and some fungi as revealed by an agar incorporation assay method. Gram positive bacteria, however, were not inhibited. Rather, some bacteria in this group...

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...

Tropical Fruit Aroma: Relevance to Oregon White Wines, the Effect of Winemaking Processes on Fermentation Esters and Volatile Thiol Levels, and the Relationship Between Sensory Perception and Volatile Chemistry

Creator:: Iobbi, Angelica
Abstract:: Aroma is one of the major components that determines the quality of wine and consumer acceptability. Fruitiness is a highly desirable aroma quality in white wines and has been well accepted by consumers across the globe. Tropical fruit aroma has been substantially studied in Sauvignon Blanc wines due to its...

Volatile composition of Pinot Noir grapes and wines under different viticultural practices in western Oregon

Creator:: Feng, Hui
Abstract:: High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...
