The Economics Of On-Farm Rice Drying In Arkansas, Clayton J. Parker, Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Globally, rice producers are faced with the temporal problem of deciding the optimal time to harvest rice. When harvested, paddy rice is typically at a harvest moisture content (HMC) between 15% and 22% and subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry, which can complicate the timing of harvest as producers try to balance the tradeoff of minimizing drying costs by waiting to harvest at lower HMC vs. maintaining higher rice quality typically observed when …

Characterization Of Jasmine Rice Cultivars Grown In The United States, Anastasia K. Mills, Ya-Jane Wang

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Jasmine rice from Thailand accounts for about 60% to 70% of U.S. imported rice, primarily due to its preference by ethnic Asians as well as the general American population. Recently new U.S. jasmine rice cultivars have been developed independently at three rice research stations in Arkansas, California, and Louisiana, but their properties have not been characterized. The objective of this research was to characterize and compare the physical appearance, chemical composition, thermal and pasting properties, cooked rice texture, and starch structures of the newly developed U.S. jasmine rice from Arkansas, California, and Louisiana, to be compared with jasmine rice samples …

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …

Ecosystem Of Bagged Grain Stored Under Naturally Ventilated Warehouse: Analysis And Modelling, Michael Ayodele Omodara

Theses and Dissertations--Biosystems and Agricultural Engineering

Grain in Africa and indeed most developing parts of the world are stored in polypropylene or jute bags arranged in stacks of varied dimensions in naturally ventilated warehouses. This practice is, however, associated with high postharvest losses due to poor temperature and moisture management during storage. This constitutes a major economic and food security challenge in these countries. Therefore, this study characterizes changes in moisture content and temperature occurring in a stack of bagged corn by determining the permeability of bag materials that influence moisture transfer and developing a mathematical model of heat and mass transfer which incorporates the unique …

Physicochemical Characterization, Structural Determination, And Molecular Dynamic Modeling Of Proso Millet Proteins For Enhanced Food Functionality, Felix Akharume

Theses and Dissertations--Biosystems and Agricultural Engineering

More than one-third of Americans today incorporate plant-based protein into their diet and about 40% believed that plant-based protein is healthier than animal protein, especially Millennials. The increasing global demand for plant-based proteins driven by the high cost of animal proteins, consumers’ desire for lean protein, vegetarianism, and the need for more sustainable green protein products have necessitated research into alternate emerging and underutilized sources of protein to complement or supplement the major plant protein in the market- soy, pea, and gluten. Therefore, this dissertation is focused on the valorization of the proteins in proso millet. Specifically, this work focused …

Evaluation Of Kentucky Grown Soft Red Winter Wheat With Sensory Evaluation For Bread-Making Capabilities And Quality, Asa Conkwright Iii

Theses and Dissertations--Nutrition and Food Systems

Soft red winter (SRW) wheat is a type of wheat that is best suited to grow in Kentucky. However, due to its low protein content, it is an undesirable flour for bread and is usually used for cakes, cookies, crackers, and pastries. This is problematic because this limits the ability for commercial bakers to have a local source of flour, forcing them to purchase from sources outside the state. In doing so, bakers are sacrificing freshness and quality. It also removes the opportunity to keep profits in Kentucky, contributing to the state’s economy. The purpose of this study was to …

Development Of A Selective Inhibitor For Kv1.1 Channels Prevalent In Demyelinated Nerves, Ahmed Al-Sabi, Declan Daly, Myles Rooney, Cian Hughes, Gemma K. Kinsella, Seshu Kaza, Kieran Nolan, J. Oliver Dolly

Articles

Members of the voltage-gated K+ channel subfamily (Kv1), involved in regulating transmission between neurons or to muscles, are associated with human diseases and, thus, putative targets for neurotherapeutics. This applies especially to those containing Kv1.1 α subunits which become prevalent in murine demyelinated axons and appear abnormally at inter-nodes, underlying the perturbed propagation of nerve signals. To overcome this dysfunction, akin to the consequential debilitation in multiple sclerosis (MS), small inhibitors were sought that are selective for the culpable hyper-polarising K+ currents. Herein, we report a new semi-podand – compound 3 – that was designed based on the modelling of …

Bridging The Food Gap: Founding And Sustaining A Food Recovery Network Chapter At Wku, Elaine Losekamp

Mahurin Honors College Capstone Experience/Thesis Projects

Food waste is a pervasive global issue with many environmental and social repercussions. While about one-third of all food produced for human consumption goes to waste, many people in the United States and the world are affected by food insecurity. Food recovery, the process of rescuing edible food that would otherwise go to waste and delivering to hungry people, is an effective solution for both food waste and food insecurity. The author of this capstone created a food recovery program at Western Kentucky University (WKU) in January 2019 and has grown the program’s scope and impact since that time. This …

Formation Of Escherichia Coli O157: H7 Persister Cells In The Lettuce Phyllosphere And Application Of Differential Equation Models To Predict Their Prevalence On Lettuce Plants In The Field, Daniel S. Munther, Michelle Q. Carter, Claude V. Aldric, Renata Ivanek, Maria T. Brandl

Mathematics and Statistics Faculty Publications

American Society for Microbiology. Escherichia coli O157:H7 (EcO157) infections have been recurrently associated with produce. The physiological state of EcO157 cells surviving the many stresses encountered on plants is poorly understood. EcO157 populations on plants in the field generally follow a biphasic decay in which small subpopulations survive over longer periods of time. We hypothesized that these subpopulations include persister cells, known as cells in a transient dormant state that arise through phenotypic variation in a clonal population. Using three experimental regimes (with growing, stationary at carrying capacity, and decaying populations), we measured the persister cell fractions in culturable EcO157 …

Natural Products For The Management Of Cardiovascular Diseases, Maha Salama, Shahira Mohammed Ezzat, Mohamed Salem

Pharmacy

Cardiovascular diseases constitute a serious public health problem. It is estimated that they are responsible for nearly 30% of world mortality. Regardless of the developments in the diagnosis and management of cardiovascular diseases, their incidence rate remains increasing. Therefore, newlines of drugs are needed to manage the expanding population of patients with cardiovascular diseases. Even though the most common existing treatments for cardiovascular diseases are synthetic molecules, natural compounds, of different chemical classes, are also being tested. Medicinal plants have been employed in the treatment of some cardiovascular diseases such as congestive heart failure and hypertension many centuries ago. Recently, …

Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge

All Master's Theses

The Sam Israel site is a precontact archaeological complex with numerous fish bones at the north end of Soap Lake, Washington. Excavated in 1976, the fish remains recovered from there were never fully analyzed prior to this research. Since this inland Columbia Plateau site had thousands of fish bones, it contained untapped potential for our understanding of ancient local fish procurement. As such, I conducted a detailed analysis of 2,862 fish bone specimens from the Sam Israel House Pit locus to: study a larger sample of fish bones in greater detail than was done before; compare the distribution of fishes …

Chulalongkorn University Theses and Dissertations (Chula ETD)

Bananas have a high potential in becoming a future staple crop due to its rapid growth rate, short harvest time, and high starch content. However, banana flour is highly retrograded which is its major limitation. The objective of this study was to study the effects of selected hydrocolloids on the pasting and gelling properties as related to the gelatinization and retrogradation of banana flour as well as its application in bread as a wheat flour substitute. Xanthan gum (XG), gum arabic (GA), hydroxypropyl methylcellulose (HPMC), and guar gum (GG) were added to banana flour at different concentrations (0.5, 1.0, and …

Is Vegan Confectionary Sold In The United Kingdom Safe For Milk Allergy Sufferers?, Faye Harrison

Electronic Theses and Dissertations

Background
Milk allergy is the most common childhood allergy. Reading food labels is important to prevent an allergic reaction. By United Kingdom (UK) law, milk needs to be listed on the food label if it used as an ingredient. Products can be called ‘free from’ milk if manufacturers have undergone rigorous process and testing to ensure it is not contaminated with milk. Precautionary Allergen Labelling (PAL) like ‘may contain milk’ statements are unregulated and can be used at manufacturer’s discretion. Similarly, ‘Vegan’ products are not regulated by law and appear to be on the increase. Objective
The study aimed to …

What The Covid-19 Crisis Is Telling Humanity, David Wiebers, Valery Feigin

Animal Sentience

The planet is in a global health emergency exacting enormous medical and economic tolls. It is imperative for us as a society and species to focus and reflect deeply upon what this and other related human health crises are telling us about our role in these increasingly frequent events and about what we can do to prevent them in the future.

Cause: It is human behavior that is responsible for the vast majority of zoonotic diseases that jump the species barrier from animals to humans: (1) hunting, capture, and sale of wild animals for human consumption, particularly in live-animal markets; …

Conducting And Analysing Semi-Structured Interviews: A Study Of Open Innovation In Food Firms In Ireland., Anushree Priyadarshini

Articles

This case study examines the use of semi-structured interviews that I used in my PhD research as a method to explore open innovation in food firms in Ireland. Literature in the field highlights that exploring innovation and the extent to which firms are open and collaborative with people outside of their organizations in conducting innovation requires detailed understanding of the concept in its natural settings. To interpret or make sense of the phenomena in terms of the meaning managers bring to it, I conducted in-depth semi-structured interviews with managers in Ireland’s largest indigenous industry, the food and beverage sector. Demonstrating …

Assessment Of Protein Quality, Lipid Metabolism, Hepatic Transcriptome And Safety Of A Silver Carp (Hypophthalmichthys Molitrix) Derived Sarcoplasmic Protein Powder., Derek Cole Warren

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fishery resources are currently operating either near optimal yield or at levels with elevated risk for fish stock depletion. A solution for overcoming limitations of natural fish resources is through utilization of less desirable fish species and fish processing by-products. Water-soluble sarcoplasm proteins consist of 25 – 30% of protein in carp, are lost in wash water during processing and can be recovered and freeze-dried to produce a protein-rich powder (CSP). The objective of this project was to evaluate the protein quality and safety of CSP, assess diets consisting of CSP or commercial milk proteins effects on lipid metabolism, and …
