The effect of erythorbic acid on the determination of ascorbic acid levels in selected foods by high performance liquid chromatography and spectrophotometry

Creator:: Tuan, Shenhsiu
Abstract:: A high performance liquid chromatography (HPLC) procedure using a LiChrosorb-NH₂ column and a eluant buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH 5.95, was developed for the successful separation and determination of ascorbic and erythorbic acids in selected food samples. Application of the method, which is sensitive, rapid and...

Iron availability from corn tortillas and cooked beans (Phaseolus vulgaris) : a study on the effect of fiber

Creator:: Garcia-Lopez, Jesus Salvador
Abstract:: Absorption of iron from foods has been reported to be inhibited by various factors including some diet components. Fiber from different sources has been observed to bind ferrous iron. This may be the reason for iron deficiencies observed in populations that consume diets high in non-digestible materials. The effect of...

Metabolic Effects in C57B/6J Mice Fed a High-Fat Diet Supplemented With Walnuts, Raspberries and Other Whole Foods

Creator:: Miranda-Garcia, Omar
Abstract:: Health benefits obtained from consumption of fruits and vegetables have the potential to improve the lifestyle of individuals. The walnut is a polyunsaturated fatty acid (PUFA)-rich whole food that is readily available in the U.S and has been shown to potentially reduce risk of Metabolic Syndrome. Furthermore, consumption of polyphenol...

Ultrafiltration of grape juice by hollow fiber membranes

Creator:: Garcia-Quintero, Zeferino Heberto
Abstract:: The feasibility of using hollow fiber ultrafi1tration for clarification, stabilization and preservation of white grape juice was evaluated. Flux and process parameters of a hollow fiber membrane ultrafi1tration unit (Romicon pilot scale, model FXS-MXII), were studied using white Riesling grape juice. Optimum processing conditions were determined for different nominal membrane...

Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

Creator:: Yuan, Fang
Abstract:: This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...

Immunomodulatory Actions of Bovine Whey Protein Isolates, Glycomacropeptide, and Their Digests: Insights from Macrophage and Human Studies

Creator:: Olsen, Wyatt
Abstract:: Whey protein isolate (WPI) and glycomacropeptide (GMP) have shown potential immunomodulatory properties. In this study, we investigated their effects on pro-inflammatory cytokine secretion using both in vitro and in vivo models. In LPS-stimulated THP-1-derived macrophages, digested WPI and GMP reduced cytokine expression, while whole GMP increased secretion. The in human...

The Extraction and Analytical Profiling of Bioactive Phospho- and Sphingolipids from Commercial Whey Protein Phospholipid Concentrate

Creator:: Ferraris, Quintin M.
Abstract:: Milk is the first source of nutrition for all mammalian neonates. The complex matrix that constitutes milk has evolved to provide optimal nutrition for the newborn, for each species, respectively. Milk fat, originating in mammary epithelial, forms lipid droplets which are stabilized in the aqueous environment by bioactive polar lipids...

Volatile composition of Pinot Noir grapes and wines under different viticultural practices in western Oregon

Creator:: Feng, Hui
Abstract:: High vegetative growth of Pinot Noir vine is a common problem in most vineyards of Oregon's Willamette Valley, where sunlight exposure and heat accumulation are limited. Consequently, growers in this region commonly use vineyard management strategies to regulate vine vigor and improve grape and wine quality. Wine quality is greatly...
