Metabolic effects of consumption of quercetin, ellagic acid, cherry, and apple phytochemical extracts in high-fat fed mice

Creator:: Smith, Sarah M.
Abstract:: Metabolic improvements and changes in gene expression were measured in mice fed polyphenol-rich extracts derived from apples and sweet cherries, and the common phytochemicals, quercetin and ellagic acid. Polyphenol-rich extracts were produced by solid phase extraction and column chromatography. Extracts and purified compounds were mixed into a high-fat (HF, 60%...

Methods of extraction and characterization of polyphenol oxidase from d'Anjou pears (Pyrus Communis L.)

Creator:: Smith, Denise Myrtle
Abstract:: Using phenolic scavengers different methods were examined to determine the optimum conditions for extracting polyphenol oxidase (PPO) from d'Anjou pears. Efficiency of the extraction was evaluated based on browning of the extract, PPO activity per g of pear tissue, absorption scan of 410 nm to -240 nm, and the isozyme...

Development of a method to measure protein in red wines : a survey of protein, mannan and tannin in Pinot noir wines

Creator:: Smith, Mark R.
Abstract:: A number of methods to isolate and quantify protein in Pinot noir wines were evaluated. The combination of precipitation by acetone containing 10% w/v trichloroacetic acid followed by quantification with the Bradford assay, reported in yeast invertase equivalents yielded the most accurate results when compared to micro-Kjeldahl analysis. The technique...

Adhesive property of bacteria and its relationship to microbial spoilage of shrimp

Creator:: Smith, John B.
Abstract:: Pacific shrimp (Pandalus jordani) was washed repeatedly and the eluted bacteria were enumerated and identified. Selected isolates were tested for their adhesive properties. Washing reduced the microbial load by 3.84 to 42.04%. The bacteria which most resisted wash-off were Staphylococcus and Pseudomonas spp. The easiest to wash off was Flavobacterium...

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....

Financial recordkeeping practices of self-employed dietetic practitioners

Creator:: Cox, Nancy R.
Abstract:: The practice of dietetics has changed over the past several years to include an increasing number of dietitians working in private practice. The 1986 census of The American Dietetic Association identified 2,383 (4.3%) of the membership as active in the Consulting Nutritionist in Private Practice group. Private practice opportunities have...

Microbial stability of fresh cut pineapple and pineapple juice pasteurized by step-pulsed and static ultra high pressure treatments

Creator:: Aleman-Ordonez, Giovanna Dominick
Abstract:: Static ultra-high pressure (200, 270, and 340 MPa) and sinusoidal and step-pressure (0-270 MPa) pulses were compared by determining their effects on bacteria and yeast survival counts. Samples were commercial pineapple chunks used as is and fresh cut pineapple and pineapple juice inoculated with Saccharomyces cerevisiae 2407-1a. Surviving bacteria and...

An analytical and sensory evaluation of the aroma volatiles of Tuber gibbosum

Creator:: Marin, Anna B.
Abstract:: The aroma of Tuber gibbosum, a native Oregon truffle, was characterized using two distinct techniques. Volatile aroma constituents were identified by chemical analysis, and sensory characteristics were determined by examining response of the general populace to the truffle aroma. Truffle samples from four maturity ranges, as determined by microscopic examination...
