Recognizing Food As Part Of Ireland’S Intangible Cultural Heritage, Máirtín Mac Con Iomaire

Articles

Drawing on evidence from across a range of disciplines (literature, folklore, history, sociology, etc.), this paper explores the lack of an iconic link between Ireland and food, explaining the reasons why Ireland and food are not immediately linked in the popular imagination. It argues for recognition of foodways as a significant element in Ireland’s intangible cultural heritage. It highlights and interrogates constructs, such as ‘national’ and ‘regional’ cuisines, charting the growing scholarship around Irish food history from the ground breaking work of A.T. Lucas and Louis Cullen to a recent emerging cluster of doctoral researchers. The paper identifies the potential …

Stability Analysis Of Immunogenic Gliadin Accumulation In Hard Red Spring Wheat (Triticum Aestivum L.), Stacy Lindblom-Dreis

Electronic Theses and Dissertations

Misconceptions regarding plant breeding objectives have led to speculation regarding the increasing prevalence of gluten intolerance, wheat allergy, and celiac disease. It is thought that contemporary wheat cultivars accumulate more immunogenic proteins than older cultivars because of supposed genetic changes effected through plant breeding strategies. This study evaluated the stability of gliadin accumulation in 191 hard red spring wheat cultivars grown in 12 location-years. Two enzyme-linked immunosorbent assays (ELISAs) were developed. A paired t test (N = 34) failed to find a statistically significant difference between the experimental ELISAs and the commercial R5 assay measures of mean gliadin (t = …

Microencapsulated Ascorbic Acid: Development, Characterization, And Release Profile In Simulated Gastrointestinal Fluids, Michele Cristina Rodrigues Da Cruz, Camila Augusto Perussello, Maria Lúcia Masson

Articles

The aim of this study was to produce ascorbic acid (AA) microcapsules by complex coacervation, characterize them, and evaluate the release profile in simulated gastrointestinal fluids. The microcapsules were made of gelatin and pectin at concentrations of 1.0, 2.0, and 3.0%. The coacervated microcapsules were assessed for morphology (by optical microscopy and scanning electron microscopy), water activity (Aw), hygroscopicity, solubility, encapsulation efficiency (EE), thermal behavior, and AA release profile. The AA microcapsules were characterized by low solubility, low hygroscopicity, high thermal stability, and low diameter (<10 μm), with EE ranging from 23.7 to 94.3%. The release profile was faster in gastric fluid (pH 1.8) than in intestinal fluid (pH 6.8). The sample containing 2.0% of wall material and 50% (w/w) of the simple emulsion (core) had the highest EE and the best in vitro release profile, with release of only 68% of AA in 120 min in the gastric fluid.

Practical applications Ascorbic acid (AA) is widely used in the food industry as an …

Assessing Environmental Flow Targets Using Pre-Settlement Land Cover: A Swat Modeling Application, Sean J. Zeiger, Jason A. Hubbart

Faculty & Staff Scholarship

Determining environmental flow requirements to sustain aquatic ecosystem health remains a challenge. The purpose of this research was to quantify the extent of current flow alterations relative to baseline hydrologic conditions of a simulated historic flow regime prior to anthropogenic flow disturbance (i.e., pre-settlement flows). Results allowed assessment of the efficacy of environmental flow targets based on pre-settlement land cover in a contemporary mixed-land-use catchment (i.e., urban, agricultural, and forested). Pre-settlement flows were simulated using the Soil and Water Assessment Tool (SWAT). Pre-settlement land cover, based on soil physical characteristics, was used to simulate pre-settlement flows with the SWAT model. …

Exploring The Short-Term Effects Of Probiotic And Prebiotic Supplementation On The Microbiota And Physiology Of Male C57bl/6 Mice, Miguel Angel Rivas

Wayne State University Theses

The gut microbiome may play a role in the development of chronic diseases like obesity, diabetes, and heart disease. Diets including prebiotics or probiotics can alter the abundance of gut bacterial groups and have subsequent health effects. In this study we wanted to establish a method for comparing the benefits of commercial supplements that alter the microbiota by monitoring fecal microbial profiles in male C57BL/6 mice (n = 24) exposed to 15 days of dietary supplementation. A probiotic diet (VSL#3) and a prebiotic diet (potato starch) were compared to a standard diet (n = 8 for each group). Microbial profiles …

Dental caries is one of the most concerning chronic diseases, Streptococcus mutans is one the most prominent contributing bacterium. S. mutans metabolizes sugar in processed foods to demineralize the tooth’s surface leading to tooth caries. This study focuses on whether green tea polyphenols epigallocatechin gallate (EGCG), and/or its modifications, palmitoyl-epigallocatechin gallate (P-EGCG) and epigallocatechin-3-gallate-stearate (EGCG-S), can reduce the number of S. mutans in different concentrations of sucrose. A colony forming unit assay was utilized to test viability. Results suggested that the tea polyphenols were efficient in inhibiting S. mutans up to 5 grams of sucrose per 100ml of artificial saliva …

Green Tea Polyphenols As Potential Food Additives, Danxia Shi

Theses, Dissertations and Culminating Projects

As time has progressed, companies have increasingly produced foods for longer term storage. This has led to an increased use of food preservatives in processed foods. People have now come to expect many foods to have a significantly longer shelf life, and this is a matter of government concern for public health due to foodborne contaminations. Foodborne illnesses have become a common problem caused by bacteria (i.e. Escherichia coli). Finding an effective natural preservative source might be better received by the public and alleviate some health concerns over chemical sources. The most important active ingredient found in green tea is …

Differentiation Of Potential False Positives From Human Saliva Using Raman Spectroscopy For Forensic Purposes, Selina Casadei

Legacy Theses & Dissertations (2009 - 2024)

Traces of body fluids can be found at a crime scene. Being able to identify and differentiate the body fluids while preserving DNA is fundamentally important for forensic applications. Saliva is an important body fluid that can be found on bite marks, cigarette butts, and more, being an excellent source for DNA extraction. Current tests for saliva and other body fluids are destructive and body fluid specific, and are prone to false positives. Our laboratory has developed a universal method for identification of all main body fluids; saliva, semen, sweat, peripheral blood, and vaginal fluid, using Raman spectroscopy combined with …

The Effects Of Chitosan On Resveratrol-Loaded Zein Nanoparticles, Brian Sohn

Undergraduate Research Symposium Posters

Resveratrol is a naturally occurring polyphenolic compound showing health benefits, including anti-carcinogenic, anti-microbial, anti-HIV/AIDS, neuro-protective, and cardio-protective activities. It has been proposed as a promising dietary supplement or functional ingredient in foods to lower the prevalence of many chronic diseases. However, due to the molecule’s chemical instability, low bioavailability, and poor water solubility, its application was vastly limited. Therefore, extensive research has been conducted regarding microencapsulation of resveratrol. In this study, resveratrol was double encapsulated with zein, a prolamine protein found in maize, and chitosan, a hydrophilic, linear polysaccharide derived from chitin via a deacetylation reaction. Due to their biocompatible, …

Healthy alternatives can be germinated cereals and legumes, which undergo chemical compositional changes producing smaller size molecules for easier digestion and generate bioactives that can have health benefits. The objective of this research was to develop a healthy and nutritional snack chip from germinated rough rice and germinated green gram that will be easier for the body to digest, provide much higher protein than conventional chips or crackers with low glycemic index. Rough rice and …

Determining Millennial Food Buying Preferences: Based On Product Marketing With “Buzzwords”, Victoria N. Hamilton

Theses and Dissertations--Community & Leadership Development

This research focuses on the importance on the Millennial Generation and their perceptions of food buzzwords. Since the Millennial Generation is the largest group purchasing and preparing their own foods, the food industry is becoming dependent on their buying preferences. A survey reflected the participants’ demographics and their buying preferences based on a series of food buzzwords when they are purchasing foods. Results show the Millennial Generation prefers “local” buzzwords. As the Millennial Generation continues to purchase foods for themselves and their families, it can be expected their choices will encourage others to do the same based on their family …

Towards A Healthier Chocolate Formula Which Is Rich In Polyphenols And Low In Fat, Lakmani Tharaka Galaniha

Theses and Dissertations--Nutrition and Food Systems

Chocolate is a food that is craved by many in the world and healthy chocolates have become a current topic in the healthy eating trend. The healthiness of a chocolate depends mainly on the polyphenol, fat and sugar contents. Although the literature serves several interventions to reduce the fat content and total calorie content of chocolates, it does not provide many interventions that consider both improving the polyphenol and reducing the fat content simultaneously. Considering this gap in the literature, this research project sought to develop a chocolate that is both low in fat and high in polyphenol content, without …

Sodium Caprate Enables The Blood Pressure-Lowering Effect Of Ile- Pro-Pro And Leu-Lys-Pro In Spontaneously Hypertensive Rats By Indirectly Overcoming Pept1 Inhibition, John Gleeson, Jesus Maria Frias, Sinead Ryan, David J. Braydon

Articles

The tripeptides, Ile-Pro-Pro (IPP) and Leu-Lys-Pro (LKP), inhibit angiotensin-converting enzyme (ACE) resulting in lowered blood pressure. Our hypothesis was that the medium chain fatty acid permeation enhancer, sodium caprate (C10), may prevent the decrease in permeability of the tripeptides when PepT1 is inhibited by glycyl-sarcosine (Gly-Sar), a situation that may occur in the presence of food hydrolysates. Using Caco-2 monolayers and isolated rat jejunal tissue, the apparent permeability coefficients (Papp) of [3H]-IPP and [3H]- LKP were assessed in the presence of Gly-Sar with and without C10. Gly-Sar decreased the Papp of both tripeptides across monolayers and isolated jejunal tissue, but …
