Breastfeeding Media Coverage And Beliefs During The Covid-19 Pandemic In Mexico: Implications For Breastfeeding Equity, Mireya Vilar-Compte, P. Gaitán‐Rossi, E. C. Rhodes, V. Cruz‐Villalba, R. Pérez‐Escamilla

Department of Public Health Scholarship and Creative Works

Background: Because breastfeeding offers short- and long- term health benefits to mothers and children, breastfeeding promotion and support is a public health priority. Evidence shows that SARS-CoV-2 is not likely to be transmitted via breastmilk. Moreover, antibodies against SARS-CoV-2 are thought to be contained in breastmilk of mothers with history of COVID-19 infection or vaccination. WHO recommends direct breastfeeding as the preferred infant feeding option during the COVID-19 pandemic, even among women with COVID-19; but conflicting practices have been adopted, which could widen existing inequities in breastfeeding. This study aims to describe how information about breastfeeding was communicated in Mexican …

Data Analytics For Sustainable Food And Agriculture Systems, Megan Lord Reavis

Graduate Theses and Dissertations

The increasing concentration of anthropogenic greenhouse gases in the atmosphere is altering the climate, posing a serious threat to global agriculture and food security. Agriculture and food production contribute a quarter of all GHG emissions produced, so there is a critical need to limit emissions in this area while increasing food production to feed the anticipated 10 billion people by 2050. To address the needs of the future, data-driven solutions are needed to guide decision-making and provide support for actionable climate mitigation and survival strategies. Research efforts must be focused on analyzing problems on multiple scales, identifying new ways to …

Wear Behaviors Of Process Cheese With Varying Formulations And The Development Of Predictive Models On Shreddability, Jason Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Process Cheese is manufactured by grinding, mixing, and heating with agitation one or more of the same varieties of natural cheese with an emulsifying agent to create a cheese with desirable properties. After process cheese is made, it is often sliced or shredded. Some of its properties affect how well it can be sliced or shredded and can lead to loss of material due to cheese sticking to equipment or being too crumbly. The loss of material, called wear behavior can incur significant losses to cheese manufacturing operations. The purpose of this study was to produce process cheese formulations with …

Averting The Looming Food Crisis: A Clarion Call To Immediate And Near-Term Policy Action, Alwan A. Hassan

Economic and Financial Review

Nigeria suffers from food insecurity and poverty. It is estimated that the number of hungry people in Nigeria is over 53 million, which is about 25.0 per cent of the country’s total population of about 212 million. Also, about 43.0 per cent of Nigerians live below the poverty line. These statistics are worrisome, given that Nigeria, in the 1950s and 1960s, was not only self-sufficient in food production, but was also a net exporter of food to other regions of the continent (Ajayeoba, 2010). A nation is food secure when food is available and accessible in sufficient quantity and quality …

Averting The Looming Food Crisis: A Clarion Call To Immediate And Near-Term Policy Action, Adeleye O. Oyebade Mni

Economic and Financial Review

Food is defined by Britannica, a web-based encyclopaedia, as any substance consisting of protein, carbohydrate, fat, and other nutrients used in the body of an organism to sustain growth and vital processes, and to furnish energy.8 In a similar definition, Wikipedia described food as any substance consumed to provide nutritional support for an organism; adding that food is usually of plant, animal or fungal origin, and contains essential nutrients. The above definitions explain why food is viewed as an essential need of life. However, the production of food has been declining in recent times for some reasons, including the adverse …

Averting The Looming Food Crisis: A Clarion Call To Immediate And Near-Term Policy Action, Emmanuel A. Onwioduokit

Economic and Financial Review

Discussions on food security have gained traction in the recent past, especially in Africa and other developing economies. Several horrifying images of famished families, particularly around “The Horn of Africa” including Somalia, Ethiopia, and some parts of Kenya, projected globally in both the print and electronic media vividly illustrate the perils of food crises. In Nigeria, food constitute a substantial share of family budgets, particularly for low-income households. When prices of essential foods items increase poorer people suffer the adverse impacts more disproportionately. While clothing and shelter are basic necessities of life, food remains the most vital, given its centrality …

Enzyme Kinetics, Molecular Docking, And In Silico Characterization Of Canary Seed (Phalaris Canariensis L.) Peptides With Ace And Pancreatic Lipase Inhibitory Activity, Uriel Urbizo-Reyes, Andrea M. Liceaga, Lavanya Reddivari, Kee-Hong Kim, Joseph M. Anderson

Department of Food Science Faculty Publications

The bioactivity of canary seed peptides (CSP) towards metabolism-regulating enzymes was evaluated. Peptides with angiotensin-converting enzyme (ACE), dipeptidyl peptidase IV (DPP-IV), and pancreatic lipase activity remained stable (p < 0.05) to simulated gastrointestinal digestion (SGD). CSP-SGD were transported efficiently (>10%) through the Caco-2 monolayer, indicating absorption through the intestinal epithelium. Lineweaver-Burk plots demonstrated that CSP-SGD act as mixed-type inhibitors for DPP-IV and α-glucosidase. Furthermore, CSP-SGD were potent as antihypertensive and antiobesity agents. Molecular docking and in silico analyses were targeted to understand CSP-SGD interactions with ACE and pancreatic lipase. ACE-inhibitory peptides (LHPQ, QTPHQ, KPVPR, and ELHPQ) acted as non-competitive inhibitors by destabilization of the transition state and Zn(II) coordination in …

Growth Kinetics Of Salmonella Spp. During Post-Harvest Storage Of Fresh And Fresh-Cut Papaya, Amandeep Singh

Theses and Dissertations

Fresh produce safety is major concern in United States. Fresh produce has been associated with numerous food-borne outbreaks each year. Salmonella has been a recurring issue in the papaya industry. Since 2010, imported papayas have been implicated in 8 multistate outbreaks associated with Salmonella spp. causing 480 illnesses, 113 hospitalization and 3 deaths. The main reason behind this problem is as fresh papaya is grown on fields where they are constantly exposed to preharvest microbial contamination through contaminated irrigation water, agricultural soil, raw manure and/or feces deposited by intruding domestic or wild animals.

Food additives have been one of the traditional methods for preserving foods and are still in everyday use for multiple reasons. As the market size of processed foods grows, the use of food additives is increasing. Simultaneously, consumers try to avoid specific food additives or demand less processed foods because of several potential health concerns, suggesting the need for safe food additives.

In this environment, one group of food additives consisting of carbohydrates and fatty acids have received attention because of its nontoxicity and biodegradability with diverse functions. Notably, carbohydrate fatty acid compounds made of sucrose have been approved and …

Us Consumers' Perceptions Of Raw And Cooked Broken Rice, Matthew G. Richardson, Philip Glen Crandall, Han-Seok Seo, Corliss A. O'Bryan

Food Science Faculty Publications and Presentations

Rice supplies about 20% of the calories to the world’s consumers. Milling removes the outer husk and bran, breaking about 20% of the rice kernels during the milling process that equates to almost 100,000,000 tons of rice annually. Broken rice is discounted in price by almost half or relegated to non-human consumption. This study seeks to understand why this large percentage of rice production is discounted for human consumption. Consumers who routinely consume rice evaluated raw and cooked rice with 5%, 10%, 20%, 30% and 40% levels of brokens. Sensory analysis indicated the appearance of raw rice with high levels …

The flooring in a food processing environment can become contaminated with pathogenic bacteria in many ways including foot and equipment traffic, incoming materials, and drain backups. Turmeric (Curcuma longa L.) rhizome powder and seventeen other commercially available powdered floor treatments with a variety of active ingredients including quaternary ammonium compounds (QAC), sodium percarbonate and similar perhydrates (SPC), urea, and borax, were investigated for reducing the levels of pathogens on flooring thereby reducing the risk of cross-contamination from the floor to food contact surfaces. Some of the commercially available floor treatments were Environmental Protection Agency (EPA) registered antimicrobials while others were …

Injection Of Iodoacetic Acid Into Pre-Rigor Bovine Muscle Simulates Dark Cutting Conditions, Jared Forrest Buhler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Following the harvest of an animal, muscle will continue to produce energy in an attempt to stay alive, primarily through the pathway of glycolysis. This occurs in the form of anaerobic (oxygen-free) metabolism of glucose and glycogen, which causes the meat to acidify. This acidification process is important for proper meat quality development and when insufficient glycolysis occurs it can cause a meat defect known as dark cutting. This defect causes the color of the muscle to become very dark, increases the water-holding capacity of the meat, and causes it to feel firm and dry on the surface because the …

Influence Of External Ph And Organic Acids On Internal Ph And Acid Anion Accumulation In Listeria Monocytogenes And Escherichia Coli, Savannah R. Branson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Listeria monocytogenes and Escherichia coli are both among the most common microbial pathogens that cause foodborne illnesses and death. They both are capable of growing over a wide range of conditions. Organic acids are widely employed in the food industry to control growth of these pathogens to help prevent foodborne illnesses. There is substantial evidence that intracellular accumulation of organic acid anions is a major inhibitor to cell growth, and that many bacteria may combat anion accumulation by lowering their intracellular pH (pH_i). In this study, we followed the accumulation of acid anion into the cell pellet and …
