Aflatoxin Prevalence And Association With Maize Grain Physical And Nutritional Qualities In The Informal Markets In Meru County, Kenya, C. Cherotich, M. W. Okoth, Abong’ Go, S. W. Kariuki, E. R. Omuse

All Peer-Reviewed Publications

In Kenya, aflatoxin contamination in maize remains a persistent issue, with potential negative impacts on both public health and economic growth. Aflatoxins are toxic secondary metabolites produced by certain mold species, primarily Aspergillus flavus. The extent of Aspergillus fungal invasion in maize grains and the resulting increase in aflatoxin levels is heavily influenced by pre-and post-harvest practices. Before harvest, factors such as insect damage and exposure to warm, humid conditions increase the crop's susceptibility to Aspergillus infection and subsequent aflatoxin formation. Post-harvest, additional risks arise when kernels are damaged by pests like rats or when they are stored in unfavorable …

Investigating Consumer Perception And Wine Quality Impact On Alternative Packaging On Grape (Vitis), Mark Walker Bartz

Graduate Theses and Dissertations

The grape (Vitis species) and wine industry has major global economic impacts but faces issues with sustainability. The use of glass bottles for wine production is environmentally unsustainable due to energy-intensive manufacturing and poor recycling rates. However, wine consumers tend to associate glass bottles with higher quality over alternative wine packaging materials such as aluminum, polyethylene terephthalate (PET), and flexible bags/pouches. Since wine price and packaging influence consumers perception of wine quality, wine producers need to understand consumers to maximize profits. Thus, the overall objectives of this research were to investigate consumer perception and wine quality impact of alternative …

Knowledge Gaps About Micronutrient Deficiencies In Tanzania And The Effect Of Information Interventions, Pius Kilasy, Brandon R. Mcfadden, Kelly A. Davidson, Leah H. Palm-Forster

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Reducing micronutrient malnutrition (“hidden hunger”) in low-income countries is a global challenge, particularly among women, children, and high-poverty households. Countries like Tanzania have developed diverse strategies to combat malnutrition, including the biofortification of staple foods. However, broad awareness and knowledge of micronutrient deficiencies and beneficial foods are needed for these strategies to be effective. The objectives of this study were to (i) examine Tanzanian consumers' initial awareness and knowledge of deficiencies for four micronutrients and associated biofortified foods, and (ii) to examine the effectiveness of targeted communication approaches (i.e., information and branding) to improve knowledge. Data were collected from 1029 …

Evaluating Efficiency And Accuracy Of Three Texture Analysis Methods For Blackberry Fruit, Rhys M. Brock, Carmen Johns, Katelyn Lust-Moore, Margaret Worthington

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

A major objective of the University of Arkansas System Division of Agriculture (UADA) Fruit Breeding program is to improve the texture of blackberry (Rubus subgenus Rubus Watson). Blackberry varieties with improved fruit firmness transport and store well and may maintain superior quality under challenging postharvest conditions than softer varieties. Increased firmness may also make cultivars less susceptible to red drupelet reversion (RDR), a postharvest disorder of blackberries in which fully black drupelets revert to red after harvest. This research project aims to assess the efficiency and accuracy of three methods applied in evaluating blackberry firmness. The study compares instrumental analysis …

Understanding The Impact Of Food Insecurity Among First-Generation College Students On The University Of Arkansas Campus, Madison Price, Jennie S. Popp Ph.D., Nathan Paul Kemper, Louise Michelle Hancox

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

The purpose of this study was to: 1) better understand food insecurity among first-generation college students and how it might differ from that of other college students, and 2) gather opinions from students that may serve as solutions to alleviate food insecurity. This study was conducted with a mixed-methods survey that included both open-ended and closed-ended questions. This survey had 670 responses. Nearly 10% of respondents stated that they were experiencing food insecurity. Almost 18% stated they were first-generation college students. A greater percentage of African American (P = 0.0022) and Hispanic Latino (P < 0.0001) students were first-generation compared to all other students, while a lower percentage (P < 0.0001) of Caucasian students were first-generation compared to other students. The results suggested that first-generation students were more likely to experience nine food insecurity impacts than non first-generation students. Further, both first-generation and non first-generation students indicated low levels of knowledge and/or use of existing resources on the University of Arkansas campus that can help address food insecurity needs. Finally, both first-generation and non first-generation respondents overwhelmingly favored food insecurity solutions centered around expanding access to campus food programs through lower costs and increased awareness of existing campus resources via improved advertising.

Stream Restoration Effectiveness In Mullins Creek In Fayetteville, Arkansas, Amadeo Scott, Shannon Speir

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

Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Effects Of Wet Aging On Water-Soluble Flavor Compounds, Descriptive Flavor, Consumer Acceptability, And Willingness-To-Pay Of Beef Longissimus Lumborum Steaks, Shangshang Wang

Theses and Dissertations

This study examined the effects of wet aging on water-soluble flavor compounds, descriptive flavor, consumer acceptability, and willingness-to-pay of beef strip steaks. Twenty USDA Select boneless beef loins (NAMP #180) were dorsally divided into four equal portions, which were randomized to receive either 0, 7, 14, or 21 d of wet aging. Short-chained peptide concentration increased from 4.11 mg/g on d 0 to 5.12 mg/g on d 7 (P = 0.011) and subsequently increased to 7.14 mg/g on d 21 (P < 0.001). Cooked beef contained 1.85 mg/g less short-chained peptides than raw beef (P < 0.001). Wet aging for 21 d increased the concentrations of amino acids, which are precursors for the Maillard reaction, including methionine, threonine, cystine, serine, tryptophan, and phenylalanine (P < 0.001). Wet aging decreased the nucleotide concentrations (P ≤ 0.003) and increased hypoxanthine concentration, a compound that imparts bitter flavor (P …

Summaries Of Arkansas Cotton Research 2022, Fred Bourland

Arkansas Agricultural Experiment Station Research Series

The current economic environment continues to drive the need to produce record or near-record yields to be profitable. Price volatility in 2022 added another level of difficulty in the quest for being profitable. The cotton market saw significant movement after reaching a $1.5802 per pound high in May 2022, cotton prices corrected and more than halved in value at the October 2022 low, and then consolidated around the 80 cents per pound level in December 2022 (Cotton is Consolidating). Great uncertainties still exist for the upcoming season, most of which are outside of our control. These include, but are not …
