Solar Cooking Solutions For Haiti, Isaac Mergner
Solar Cooking Solutions For Haiti, Isaac Mergner
Graduate Theses and Dissertations
This study focuses on enhancing the efficiency of solar cooking through the use of solar cookers and heat retention boxes. The research involved testing various cooking vessels and lids in a solar cooking experiment, with a specific focus on the performance of different materials and their heat retention capabilities. The experiment aimed to increase the efficiency of solar cookers, which are popular in developing nations due to their relatively low cost. The findings indicate that the combination of a solar cooker and a heat retention box can significantly improve the cooking process, particularly in areas with limited access to cooking …
Rice Material State Diagrams: Trends Of Contemporary Cultivars And Influence Of Nitrogen Application During Production, Evans Ameyaw Owusu
Rice Material State Diagrams: Trends Of Contemporary Cultivars And Influence Of Nitrogen Application During Production, Evans Ameyaw Owusu
Graduate Theses and Dissertations
Rice is typically harvested at high moisture content (MC) levels which necessitates drying to low MC levels for safe storage. However, drying at inappropriate temperatures and durations can lead to deterioration of kernel quality such as fissure formation. Kernels with these fissures are typically associated with reduced head rice yields and significant economic losses. Material state diagrams for rice have been created by the University of Arkansas Rice Processing Program (UARPP) as a tool to aid in predicting the ideal temperatures to use during drying and tempering (a process of holding rice at the drying temperature for some duration). The …
Use Of X-Ray Imaging To Elucidate Impacts Of Drying Approach On Rice Seed Health, Samuel Olayiwola Olaoni
Use Of X-Ray Imaging To Elucidate Impacts Of Drying Approach On Rice Seed Health, Samuel Olayiwola Olaoni
Graduate Theses and Dissertations
Improper drying, which causes fissuring of rice kernels, may influence the overall seed health. This study evaluated the impacts of various drying conditions on rice fissures, seed germination and vigor. A long – grain rice cultivar with a moisture content (MC) of 15.5% w.b. (wet basis) was used during the experiments. Samples were dried as thin layers at temperatures of 30 ℃, 40 ℃ and 50 ℃ with a constant relative humidity (RH) of 50% and air velocities (AV) of 0.66 m/s and 1.65 m/s. X – ray imaging was used for fissure detection before and after drying the samples …
Radiofrequency And Gaseous Technologies For Enhancing The Microbiological Safety Of Low Moisture Food Ingredients, Surabhi Wason
Radiofrequency And Gaseous Technologies For Enhancing The Microbiological Safety Of Low Moisture Food Ingredients, Surabhi Wason
Graduate Theses and Dissertations
High heat resistance and long survival of Salmonella in low moisture food ingredients (LMFIs) such as spices and seeds are concerning as they are typically consumed without cooking. Therefore, it is challenging to effectively inactivate pathogenic bacteria without negatively impacting the quality of the treated product. This dissertation aimed to develop and evaluate novel intervention technologies: in-package radiofrequency steaming and non-thermal gaseous technologies to improve the microbial safety of LMFIs. The dissertation can be divided into three parts. The first part of this dissertation on the thermal inactivation kinetics of Salmonella and a surrogate, Enterococcus faecium NRRL B-2354on black pepper …
Use Of Microorganisms For The Enrichment Of Zn And Se By Using Solid-State Fermentation, Rashmi Rangaswamaiah
Use Of Microorganisms For The Enrichment Of Zn And Se By Using Solid-State Fermentation, Rashmi Rangaswamaiah
Graduate Theses and Dissertations
Zinc (Zn) and selenium (Se) are essential minerals for human health and naturally found in many food sources. However, the risk of Zn and Se deficiency has been recognized in several countries. As most people throughout the world consume rice, grains, and cereals as staple foods in their daily diet, which contain a certain amount of phytic acid (antinutrients), the phytic acid content inhibits mineral absorption (Zn and Se) by the human body. Moreover, the low levels of Zn and Se content found in the crop's soil also reduce the amount of minerals in the food sources. Therefore, it is …
Development Of An Intervention For Improving Food Acceptance Of People With Hearing Loss, Sara Esther Jarma Arroyo
Development Of An Intervention For Improving Food Acceptance Of People With Hearing Loss, Sara Esther Jarma Arroyo
Graduate Theses and Dissertations
Hearing loss, defined as the partial or total inability to hear sound in one or both ears, is the most common sensory deficit in adults to date. Approximately 15% of American adults aged 18 and over report some trouble hearing. The impact of hearing loss may be profound, with consequences for the social, functional, and psychological well-being of the person. Surprisingly, very little attention has been paid on whether auditory loss can significantly impact consumers’ sensory perception and overall enjoyment of food. There were four objectives of this dissertation study. Chapter 1 aimed to determine the impacts of hearing loss …
Starch Granule And Crystalline Structures With Relation To Enzyme Digestibility, Ana Isabel Gonzalez Conde
Starch Granule And Crystalline Structures With Relation To Enzyme Digestibility, Ana Isabel Gonzalez Conde
Graduate Theses and Dissertations
Porous starch produced by enzyme hydrolysis has attracted much attention for its adsorption and delivery properties. Porous starch has been successfully prepared from A-type starch, but not from B-type and C-type starches, which is partly attributed to the surface and crystalline structure. The present study aimed to characterize the role of the crystalline structure and the structure-function relationship impacting the susceptibility of starch with different crystalline polymorphs to amylase digestion. The starches were subjected to chemical modification (acid hydrolysis or surface gelatinization), physical modification (heat-moisture treatment, HMT, or high-pressure processing, HPP) or their combinations prior to amylase digestion, and the …
Study Of Weight Gain In Freshman Students At The University Of Arkansas, Lily Maleknia
Study Of Weight Gain In Freshman Students At The University Of Arkansas, Lily Maleknia
Graduate Theses and Dissertations
This study was designed to examine the poor (non-nutritional) food choices that college freshman make when living on-campus and eating at on-campus dining facilities. These poor choices lead to excessive weight gain, eating disorders, declining health and wellness, and mental health issues (i.e. depression, anxiety, lack of self-confidence). These side effects can lead to a less than desirable 1st year college experience and lack of academic success. Based on these concerns, different investigations have been performed to determine the causes of this phenomena. Given adolescent weight gain is highly linked to being overweight and obesity in adults, a better understanding …

Potential Control Of Invasive Mesquite Through Improving The Consumer’S Understanding Of Liquid Smoke Applications., Seth W. Ellsworth
Graduate Theses and Dissertations
Mesquite trees continue to invade forests and range lands in many countries across the world. The cost to remove these trees is staggering. In Texas, landowners spent $25 million over a 10- year period to clear 300,000 ha of mesquite trees, a fraction of the 22 million ha of Texas land affected by this invasion. Estimates are that the mesquite continues to negatively impact one to two percent of additional land in selected counties each year in Texas. However, the problem is not unique to Texas, but rather to the 44 species of mesquite trees, belonging to the genus Prosopis …
