Development Of Soluble Dietary Fiber Based Nanofiber Delivery System For Alpha-Tocopherol, Juan Li Jan 2013

Development Of Soluble Dietary Fiber Based Nanofiber Delivery System For Alpha-Tocopherol, Juan Li

LSU Doctoral Dissertations

The bioactive compound vitamin E is essential for human health. It has been reported to reduce the risk of cancer, cardiovascular disease, diabetes and aging. One of the main concerns about the availability of vitamin E is the stability, or lack thereof, associated with the processing and storage of it. Degradation could occur when vitamin E is exposed to light, temperature or oxygen, which results in the loss of efficacy. Also, the application of vitamin E is limited because of its poor solubility in aqueous media. Among the tocopherols contained in the vitamin E family, α-tocopherol (α -TOC) has the …

Factors Influencing Glycogen Branching Enzyme Activity In Mouse Liver, Scott Fuller Jan 2013

Factors Influencing Glycogen Branching Enzyme Activity In Mouse Liver, Scott Fuller

LSU Doctoral Dissertations

Glycogen is the storage polysaccharide in a spectrum of organisms ranging from yeast to humans. Glycogen has a highly branched structure somewhat resembling a tree or shrub, with the branch points formed by glucose molecules being joined by α 1,6-glycosidic linkages. These linkages are formed by the action of branching enzyme. Branching of glycogen is critical to health, with a lack of branching causing glycogen storage disease type IV, which is fatal in humans by age 2. While glycogen branching enzyme has been studied in clinical medicine, modulation of the enzyme has received comparatively little attention. This dissertation undertook three …

Mathematical And Computer-Based Models For Optimizing Microwave Heating Processes Of Frozen Oysters, Jie Zhang

LSU Doctoral Dissertations

Consumers with full-time jobs prefer microwavable-frozen-meals for convenience when lack time to cook. Microwaves do not require a medium for heat transfer and provide quick heating even in low thermal conductivity foods, which does not occur in conventional heating. The main problem in utilizing microwave-heating for cooking is the non-uniform temperature distribution in foods which may result in insufficient lethality of microorganisms in some part. This non-uniformity can be due to a number of factors including composition and geometry of food. The objectives of this study were to develop a mathematical-model based on Maxwell¡¯s equations for predicting the temperature distribution …

Role Of Retrotransposons As A Major Source Of Intra- And Inter-Individual Epigenetic Variations In The Mammalian Genome, Muhammad Badre Ekram

LSU Doctoral Dissertations

Transcription of retrotransposons is usually repressed by DNA methylation, but a few elements partially escape this repression mechanism. I used two approaches as my dissertation study to identify unmethylated intracisternal A-particles (IAPs) and also to understand why some of IAPs escape DNA methylation-mediated repression. Firstly, I sought to catalog the retrotransposons (LTRs and LINEs only) in the mouse genome known as ‘epialleles’ which escape the repression variably even in individuals with an identical genome sequence. Using bioinformatic approaches, 143 candidate epialleles were first identified based on their promoter activity and association with active histone modification marks. Detailed methylation analyses suggested …

Examining Neotropical Primate Community Structure At Regional And Local Scales : Insights From Taxonomic And Phylogenetic Approaches, Maria Mercedes Gavilanez

LSU Doctoral Dissertations

Understanding mechanisms underlying distribution of biodiversity remains a central issue in ecology. I integrate ecological and phylogenetic information at multiple spatial scales to better understand neotropical primate distribution and community structure. I investigate the variation within species ranges in relation to species richness and patterns of species relatedness. Results suggest positive associations among species throughout their distributions, whereby species tend to present higher richness within their ranges than average richness for the entire taxon. However, comparing empirical distributions to a null model of range cohesion suggests mechanisms other than dispersal are setting a limit to the number of species capable …

Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante Jan 2013

Effect Of Bitterness Blockers And Salt Substitutes On The Quality Of Low Sodium White Cheddar Cheese, Kennet Mariano Carabante

LSU Master's Theses

Reducing added salt in processed foods is one of the major challenges facing food industry worldwide. Salt (NaCl) replacement in a Cheddar cheese has been successfully achieved up to 25%, which qualifies it as “reduced sodium”. However, a low sodium cheddar cheese (less than 140 mg Na/ 50 g cheese) requires at least 50% of salt reduction. Bitterness is one obstacle for development of an acceptable low sodium cheddar cheese. In this study, sensory optimization of low sodium white cheddar cheese was performed. A 3-component mixture design was used: NaCl (30-60%), KCl (45-65%) and glycine (5-10%). A fixed level of …
