Nutritional Composition Changes in Alaska Pollock (Gadus chalcogrammus) During and Between Bering Sea A and B Seasons

Creator:: Hintermeister, Clara A.
Abstract:: Alaska pollock (Gadus chalcogrammus) is a schooling whitefish native to the Bering Sea that is prized for its fillets, surimi, roe, and milt. Fillets are frequently used for popular products such as fish and chips. If collected, roe and milt are commonly exported to South Korea and Japan. However, no...

Influence of cultivar and maturity on blackberry polyphenolics and investigation of sediment formation in blackberry juice

Creator:: Siriwoharn, Thanyaporn
Abstract:: The influence of cultivar and maturity on polyphenolic composition and antioxidant activity was investigated by UV-Visible spectrophotometry and analytical high performance liquid chromatography (HPLC) in commercially important blackberry cultivars and selections. The anthocyanin pigments changed tremendously with ripening. Total anthocyanins increased from 74.7-317 mg/100g fw from underripe to over ripe...

Enrichment Isolation of Brettanomyces Yeasts to Probe the Relationship Between Vineyard and Winery Populations

Creator:: Pigao, Kevin E.
Abstract:: The budding yeast Brettanomyces bruxellensis has the potential to spoil fermented beverages and cause financial losses, but also contribute positively to certain products such as Lambic beer. It is most notorious for causing “Brett” spoilage of wine, which is characterized by undesirable aromas such as “bandaid” and “barnyard”, therefore most...

Interactions between Oenococcus oeni and Brettanomyces bruxellensis during winemaking and consequences for wine quality

Creator:: DuBois, Aubrey E.
Abstract:: The growth of Brettanomyces bruxellensis is a major cause of wine spoilage due tothe production of the volatile phenols 4-ethylphenol (4-EP) and 4-ethylguaiacol (4-EG), derivatives of p-coumaric acid and ferulic acid. During the winemaking process,some microorganisms can impact the concentration of the 4-EP precursors pcoumaricand coutaric acid (tartaric acid-esterified p-coumaric...

The Impact of Malolactic Fermentation Conducted by Oenococcus oeni on Brettanomyces bruxellensis Growth and Volatile Phenol Production

Creator:: Lauderdale, Adam D.
Abstract:: Wine is particularly vulnerable to infection by Brettanomyces bruxellensis during or shortly after malolactic fermentation (MLF). While different methods and techniques enable winemakers to prevent wine spoilage due to this organism, no single intervention is universally sufficient. Moreover application of sulfur dioxide, the most commonly used of these methods, is...

“Red Light, Yellow Light!”: Evaluating the Anti-Listerial Potential of Bacillus Isolate Metabolites Using a High-Throughput Chromogenic Assay”

Creator:: Johnson, Taylor S.
Abstract:: Listeria monocytogenes contamination continues to pose challenges for the food industry and there is demand for effective methods of food preservation and protection that can also be considered clean label. A promising source of antilisterial compounds may be sourced from bacteria that produce novel byproducts. Ribosomally synthesized and post-translationally modified...

Elucidating the Patterns of Cooccurrence, Spatial Structuring, and Impact on Fermentation Metabolism in Kombucha Microbial Communities

Creator:: Harrison, Keisha Rose
Abstract:: This dissertation investigates the microbial diversity and factors influencing the assembly of microbial communities in kombucha production, using a combination of 1H Nuclear Magnetic Resonance Spectroscopy, 16S and ITS rRNA metabarcoding, and traditional culture-based microbiological methods. It also explores the diversity of kombucha starter cultures through shotgun sequencing and metabarcoding...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

Effects of Pediococcus spp. on Oregon Pinot noir

Creator:: Strickland, Matthew T.
Abstract:: This research investigated the effects of Pediococcus spp. on Oregon Pinot noir wines. Pediococcus (P. parvulus (7), P. damnosus (1), P. inopinatus (1)) isolated from Oregon and Washington state wines demonstrated differences in their susceptibility to SO₂ with some isolates growing well in model media at 0.4 mg/L molecular SO₂....
