Structure of the Royal Anne cherry cuticule with special reference to cuticular penetration

Creator:: Wilson, Lester Arthur
Abstract:: The structure of the Royal Anne cherry cuticle (Prunus avium L.) and its penetration by a SO₂-calcium bisulfite brine was determined. The structural features of the cuticle are interpreted in the light of its possible significant to cuticular penetration. The morphology of the cuticle was determined by standard histological and...

Quantification of fructose equivalents in straw extracts

Creator:: Kim, Eugene
Abstract:: Cereal and commercial grass-seed straws are abundant plant biomass materials that are currently being considered for application in industrial processes aimed at the production of biofuels, biomaterials, and biochemicals. The carbohydrate fraction of these straws is of particular interest in this context due to its chemical functionality and relative ease...

Bitterness modifying properties of hop polyphenols

Creator:: McLaughlin, Ian R.
Abstract:: This study examined whether polyphenols contribute a harsh bitterness to beer, and how polyphenols may otherwise modify beer bitterness in the presence of iso-a-acids. The experimental portions of this project were divided into effectively two segments. The first section of the study encompassed groundwork polyphenol extraction development, and the examination...

Analysis of proanthocyanidin A2 and its presence in various commercial products

Creator:: Koerner, Jayma L.
Abstract:: Proanthocyanidins (PACs) containing A-type linkages, like those found in cranberry, have been implicated as beneficial phenolic compounds in human health, but much research is still required to better understand their activity fully. One major impediment to progress has been the existence of effective analytical methods for A-type PAC quantification. This...

The blueberry : composition, anthocyanins, and polyphenolics

Creator:: Lee, Jungmin
Abstract:: Frozen blueberries were pilot-plant-processed into juice and concentrate by 2 treatments (heat and SO2), and a control. Qualitative, and quantitative anthocyanin and polyphenolic content were monitored after each processing step. Major losses occurred after the initial processing steps. Juice processing by-product contained a substantial amount of anthocyanins and polyphenolics (>42%...

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...

Application of Antimicrobial Substance in Depuration for Decreasing Vibrio Parahaemolyticus Contamination in the Pacific Oysters (Crassostrea gigas)

Creator:: Shen, Xiaoye
Abstract:: Vibrio parahaemolyticus is the leading cause of foodborne illnesses associated with seafood consumption. Consuming raw or undercooked seafood contaminated with V. parahaemolyticus can result in development of acute gastroenteritis with symptoms of nausea, vomiting, abdominal cramping and watery diarrhea within 24 hours of infection. Illness is usually self-limited and lasts...

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...

Effects of refrigeration storage and processing technologies on the bioactive compounds and antioxidant capacities of blackberries ('Marion' and 'Evergreen')

Creator:: Wu, Ruyi
Abstract:: The objective of this project was to investigate the effects of refrigeration storage and processing technologies on the quality and nutraceutical benefit of blackberries. 'Marion' and 'Evergreen', the two major blackberry varieties in Oregon, were evaluated in this study. For refrigeration storage, fresh fruit were packed in clam-shell containers right...

Investigation of Bioactive Compounds in Different Types of Fruit Pomace and Their Applications as Bulk Materials for Creating Biocomposite

Creator:: Gouw, Virginia P.
Abstract:: The objectives of this study were to evaluate the physicochemical properties and bioactive compounds from four different types of fruit pomace, including apple, blueberry, raspberry, and cranberry, and further to investigate the feasibility of creating apple pomace based biocomposite boards using thermal compression molding and to optimize the biocomposite formulations...
