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...

Evaluation of the effects of nutrient supplementation on low nitrogen Chardonnay

Creator:: Specht, Anna Louise
Abstract:: Low nitrogen Chardonnay juice from an Oregon winery was fermented with a series of nutrient supplements, including diammonium phosphate (DAP), Fermaid K, Superfood, yeast extract, yeast hulls and thiamine. These treatments were evaluated for their contribution to the yeast assimilable nitrogen content (YANC) of the juice, which consists of the...

Development of analytical methodology for verification of authenticity of apple juice

Creator:: Lee, Hyoung S.
Abstract:: Apples growing in New Zealand, Argentina, Mexico, Michigan and Washington were used to provide the compositional data and to develop the analytical procedures for the use in verification of authenticity of apple juices. High Performance Liquid Chromatography (HPLC) techniques were applied for glucose, fructose, sucrose, sorbitol, malic, citric, quinic, shikimic,...

Malate and tartrate in Oregon grapes

Creator:: Norton, Kerry M.
Abstract:: In western Oregon the titratable acidity of grapes at harvest may in some seasons be higher than desirable for making quality wine, due to the retention of malic acid. The purposes of this study were 1) to investigate the effects of a vineyard cultural practice, cluster exposure at veraison by...

Influence of polyphosphates on the emulsifying capacity of milk and meat proteins

Creator:: Cummins, Armando
Abstract:: The influence of polyphosphates upon the emulsification of enzymatic hydrolyzates of casein and lactalbumin and upon salt-soluble meat proteins was determined by a model system in which oil-in-water emulsions were formed. Sodium acid pyrophosphate, sodium tripolyphosphate and sodium hexametaphosphate were mixed together in a weight ratio of 4:2:4, respectively, to...

Apparent inhibition of Pacific whiting surimi-associated protease by whey protein concentrate

Creator:: Piyachomkwan, Kuakoon
Abstract:: Surimi is a seafood product which is used to manufacture restructured products such as artificial crab and lobster. Surimi is produced from fish fillets by washing to remove sarcoplasmic proteins and increase the concentration of myofibrillar proteins, and mixing with cryoprotectants. A valuable attribute of surimi is its ability to...

Identification and characterization of a heat stable protease in arrowtooth flounder (Atheresthes stomias) and methods of inhibition in surimi

Creator:: Wasson, Diana H.
Abstract:: A heat stable protease was identified as the cause of textural degradation in cooked arrowtooth flounder (Atheresthes stomias) muscle. Maximum proteolytic activity in the fish muscle was observed between 55°C and 60°C and myosin heavy chain appeared to be the primary substrate for the enzyme. Degradation of this myofibrillar protein...

Characterization of Pacific whiting protease and food-grade inhibitors for surimi production

Creator:: Weerasinghe, Vasana C.
Abstract:: Cathepsin B was the most active cysteine proteinase in the Pacific whiting (Merluccius productus) fish fillet, and cathepsin L in surimi when the activities of the most active cysteine proteinases (cathepsin L, B, and H) were compared. Cathepsin L showed maximum activity at 55°C in both fish fillet and surimi,...

Alternative products from Pacific whiting : fresh surimi and texturized mince

Creator:: Pipatsattayanuwong, Siriporn
Abstract:: The major portion of Pacific whiting (PW) is commercialized in the form of frozen surimi. Alternative products for PW were investigated focusing on fresh surimi and texturized meat from PW mince. Fresh surimi is made without additives and kept refrigerated instead of frozen. Texturized meat is a meat-like product made...
