Food Insecurity: United States, Courtney Handzel
Global Issues in Public Health
Food insecurity is a global issue and has caused struggles to millions of people, specifically in the United States. This environmental issue involves not having the resources to obtain adequate food supply. The economic and social influences that affect food insecurity leave vulnerable populations, such as low-income families and minority races, at a greater disadvantage. This issue causes serious health complications to arise too, the most common being diabetes. The increased risk of diabetes due to food insecurity has been studied on several occasions and the results all show the correlation, lack of food security increases the risk of diabetes. …

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 …

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, …

The purpose of the study was to produce soy protein isolate(SPI) micro emulsion droplet by ultrasonication and microfluidization Techniques. The changes of SPI emulsion temperature, average droplet diameter and size distribution were observed. The distribution curve of SPI droplet processed by ultrasonication has two peaks and that of SPI droplet processed by microfluidization has single peak. The results indicate that the SPI emulsion processed by high pressure is more homogeneous. The capability of reducing size by ultrasonic process (1 200 W) is very limited, and the SPI emulsion tends to agglomerate after a long time of ultrasonic process. Microfluidization (microseconds, …
