Effect Of Enrichment-Bleaching And Low Oxygen Atmosphere Storage On All-Purpose Wheat Flour Quality, Jonathan Myers Swindler
Effect Of Enrichment-Bleaching And Low Oxygen Atmosphere Storage On All-Purpose Wheat Flour Quality, Jonathan Myers Swindler
Theses and Dissertations
All-purpose wheat flour is a useful long-term storage commodity, but is subject to off-odor formation. Although flour stored in a low oxygen atmosphere should inhibit rancid odor formation, it elicits consumer complaints about odor. The purpose of this study was to examine off-odor development in all-purpose wheat flour during ambient and elevated storage by determining the effect of low oxygen atmosphere and enrichment-bleaching on quality as measured by, free fatty acids (FFA), flour descriptive sensory analysis, conjugated dienes, headspace volatiles, bread consumer sensory analysis, color, loaf volume, and vitamin analysis. Enriched, bleached (EB) and unenriched, unbleached (UU) flour was stored …
Accelerated Shelf Life Determination Of Antioxidant Stabilized High Oleic Sunflower And Canola Oils In Plastic Bottles, Christine Nicole Shearer
Accelerated Shelf Life Determination Of Antioxidant Stabilized High Oleic Sunflower And Canola Oils In Plastic Bottles, Christine Nicole Shearer
Theses and Dissertations
Vegetable oil is an important commodity; however, the majority of commercially available vegetable oils have a fairly short shelf life, which limits their usefulness for long term food storage, disaster relief, space travel, food aid programs, and military rations. Vegetable oils with high oleic acid and reduced linolenic acid contents, especially with added antioxidant combinations, were previously found to have significantly longer oil stability index (OSI) values than traditional vegetable oils. This study used accelerated shelf life testing to estimate the ambient shelf life of high oleic sunflower oil (HOSUN) and high oleic canola oil (HOCAN), each containing 1,000 ppm …
