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...

Ultrafiltration of fruit juice and wine

Creator:: Flores Gaytan, Jose Humberto
Abstract:: The possible effect of oxidation [processing with or without sulfur dioxide (±S0₂)] and of pre-ultrafiltration treatment of juices with enzymes and fining agents on flux, and on juice color, composition and stability was investigated. White Riesling juice was ultrafiltered with a Romicon system operated with a nominal molecular weight cut-off...

Two Studies Addressing Practical Needs of Wheat Farmers, Processors, and Breeders : Changes in Falling Number and Alpha-amylase During Grain Storage, and Improved Predictions of Wheat-flour Dough Properties

Creator:: Adams, Mike R.
Abstract:: Wheat (Triticum aestivum) is a globally traded staple food crop. The diverse and pleasing nature of wheat-derived products is a result of the complex interactions of the polymeric components from the wheat endosperm. Changes in the functionality of these polymeric components, as a result of changes in growing conditions or...

The effects of processing on sodium-potassium and calcium-phosphorus ratios in foods

Creator:: Ronan, Kathleen M.
Abstract:: The objective of this study was to determine the effects of processing on sodium - potassium and calcium - phosphorus ratios in tuna canned in oil and in water, peanut butter, white and whole wheat flours. Mineral levels were determined by atomic absorption spectrophotometry in food samples at various stages...

The effect of nitrogen, irrigation, and cultivation on Pinot noir juice and wine composition from the Willamette Valley, Oregon

Creator:: Wall, Katherine Elizabeth
Abstract:: This study investigated how manipulating vineyard nitrogen status, irrigation levels and cultivation practices would effect nutrient composition, and anthocyanin and phenolic accumulation in Pinot noir juice and wine from a commercial Willamette Valley Oregon vineyard. Pinot noir fruit was sourced from a vineyard trial in the Benton Lane Vineyard, located...

Studies in cereal science : arabinoxylans, glutenins, and their interactions; determining optimum water addition in noodle doughs; and quality and nutritional traits in a hard x soft wheat cross

Creator:: Kongraksawech, Teepakorn
Abstract:: The major components of wheat flour are keys to its functionality in processing and product quality. The major components, other than the lipids, are polymers: starch, protein, and non-starchy polysaccharides (NSP). In wheat NSP are primarily arabinoxylans (AX). These components are compartmentalized in the grain but are forced into close...

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...

Science and efficacy of mild sodium hydroxide treatments in enzyme-based wheat straw-to-glucose processing

Creator:: Sophonputtanaphoca, Supaporn
Abstract:: The work described in this dissertation focused on chemistry related to the use of aqueous sodium hydroxide as a treatment in the processing of wheat straw. A major emphasis was the comprehensive evaluation of straw component partitioning due to sodium hydroxide (NaOH) processing. This was evaluated over a range of...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...

Relationships of cellulose and pectic substances to the texture of secondarily bleached cherries

Creator:: Ross, Nicholas Dutton
Abstract:: Research was initiated to find a secondary bleach to remove brown discoloration on sulfur dioxide brined sweet cherries. In addition, studies were carried out to determine the effects on texture of not only the secondary bleaches, but also the primary bleach (sulfur dioxide). Three bleaches were found to remove the...
