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 …

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 …

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.

Identification, Aggressiveness And Mycotoxin Production Of Fusarium Graminearum And F. Boothii Isolates Causing Fusarium Head Blight Of Wheat In Nebraska, Esteban Valverde-Bogantes
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Fusarium head blight (FHB) is an economically important disease caused by several Fusarium species affecting wheat. Besides causing significant yield losses, infected grain may be contaminated with mycotoxins, primarily trichothecenes, that are harmful to both humans and animals. In recent years, reports of shifts in FHB pathogen populations in North America have highlighted the need for increased vigilance. This dissertation describes a four-year survey evaluating the species, trichothecene genotype and phenotypic diversity of FHB pathogens infecting Nebraska wheat. Most of the isolates were identified as F. graminearum (n=67). Additional species included F. boothii (n=3), F. poae (n=2) and F. acuminatum …

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 …

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 …

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 …

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 …

In this paper, we discuss dietary and possible medicinal practices of an Early Formative period (2000–1000 BCE) community transitioning from Archaic-style to Formative-style lifeways. The results we present come from the analysis of plant residues, including microbotanical and macrobotanical remains, which were excavated at the village site of La Consentida in coastal Oaxaca, Mexico. Phytoliths and starch grains were recovered by sonication from twenty ceramic and lithic artifacts. The microbotanical analyses identified plant remains from four different families: Bombaceae (flowering plants), Dioscoreaceae (yam family), Fabaceae (bean family), and Poaceae (grasses, including maize). We also report on limited macrobotanical analysis, including …

Toxins from marine animals provide molecular tools for the study of many ion channels, including mammalian voltage-gated potassium channels of the Kv1 family. Selectivity profiling and molecular investigation of these toxins have contributed to the development of novel drug leads with therapeutic potential for the treatment of ion channel-related diseases or channelopathies. Here, we review specific peptide and small-molecule marine toxins modulating Kv1 channels and thus cover recent findings of bioactives found in the venoms of marine Gastropod (cone snails), Cnidarian (sea anemones), and small compounds from cyanobacteria. Furthermore, we discuss pivotal advancements at exploiting the interaction of κM-conotoxin RIIIJ …
