Impact of Preharvest Weathering, Without Sprouting, on the Quality of Soft White Winter Wheat in the U.S. Pacific Northwest

Creator:: Smith, Jordan L.
Abstract:: When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....

Descriptive analysis of Pinot noir juice and wine qualities

Creator:: Ludwig-Williams, Nancy
Abstract:: The overall purpose of this study was to develop sensory evaluation methodology whereby wine quality can be predicted from juice quality. Descriptive analysis was used by a trained panel to describe Pinot noir juice and wine from three sources. From each source, one wine and four juice samples (a control...

Investigation of postharvest quality and storability of hardy kiwifruit (Actinidia arguta 'Ananasnaya')

Creator:: Landis Fisk, Connie
Abstract:: The objectives of this project were to determine the effects of harvest maturity, packaging, and storage conditions on subsequent fruit quality of Actinidia arguta ‘Ananasnaya’ and to investigate the use of edible coatings to improve fruit quality and storage life. The influences of harvest maturity (6.0, 8.7, 9.1, and 15.1%...

Gel electrophoretic analysis of bovine sarcoplasmic proteins

Creator:: Petropakis, Heracles John
Abstract:: The electrophoretic behavior of sarcoplasmic proteins was investigated by the use of vertical acrylamide gel electrophoresis. The first part of the study was concerned with the separation of sarcoplasmic proteins extracted at different times of post-mortem aging. Electrophoresis of the sarcoplasmic extracts by the discontinuous technique, using ten percent acrylamide...

Impact of seasonal variation and growing environment on blackberry aroma

Creator:: Wang, Yuanyuan
Abstract:: Blackberries have been enjoyed for their delicious flavor and high nutritional value for hundreds of years. In North America, blackberries were cultivated since 1850-1860. Blackberries have their characteristic and unique aromas depending on the cultivar and growing conditions. The objective of this study was to evaluate the impact of seasonal...

Edible coatings to improve storability and enhance nutritional value of strawberries (Fragaria ananassa) and raspberries (Rubus ideaus)

Creator:: Han, Chunran
Abstract:: Strawberries {Fragaria ananasa) and raspberries {Rubus ideaus) are good sources ofmany important nutrients, and have great potential to improve human health. However, they are highly perishable and have a very short shelf-life mainly due to the attack of fungi and high respiration rate. Edible coatings, especially chitosan-based coatings have been...

Proteolytic and chemical changes of some minor nitrogen compounds and extra protein of bovine muscle during aging

Creator:: Petropakis, Heracles John
Abstract:: Investigations were conducted to determine whether the low molecular weight nitrogen compounds and the extra protein complex of bovine psoas major muscle were altered during a 12-day aging period. Electrophoretic studies of soluble proteins either before or after gel filtration on Sephadex G-25 columns indicated that the soluble proteins were...

Aflatoxin B₁ metabolism by rainbow trout (Salmo gairdneri)

Creator:: Schoenhard, Grant Louis
Abstract:: Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy confirmed the microsomal...

Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

Creator:: Jetti, Rajesh R.
Abstract:: Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...

Development of anthocyanins and proanthocyanidins in Pinot noir grapes and their extraction into wine

Creator:: Pastor del Rio, Jose L.
Abstract:: Color stability and mouth feel quality are two of the most important aspects of red wine quality. Anthocyanins and proanthocyanidins are responsible for these attributes and it has been shown that weather conditions during the growing season and grape maturity can effect these components in wine. However, investigations into proanthocyanidin...
