Research Skills Combining Microbes And Social Equity (Avs 590-0980), Sue Ishaq, School Of Food And Agriculture

General University of Maine Publications

To understand a microbiome, you must learn about the bustling community of microorganisms and the complex ecosystems they live in, because one cannot exist without the other. So, too, does microbiome research rely on understanding the lives and ecology of humans, because there is no aspect of human life which does not involve microbes in some way. To become better microbiome researchers, we must understand social and environmental contexts which affect humans and, in many cases, prevent them from making choices which result in beneficial microbial exposures. This symposium will focus on developing research skills to create transformative research, including …

Envisioning A Bold Food Waste Policy For Maine: A Mixed-Methods Study Into The Context Of Landfill Diversion Of Food Waste, Dominique Danielle Dispirito

Honors College

Landfilled organics waste both natural and financial resources by discarding usable materials that could bolster food security programs and composting efforts. According to the Drawdown Project, one-third of the food we produce in the United States goes to the landfill without ever reaching someone’s plate, contributing to leachate at disposal sites and accounting for more greenhouse gasses than the entire airline industry. As communities across the state struggle to support the 1 in 6 Mainers experiencing food insecurity with dwindling financial resources and limited personnel, food waste diversion provides a local solution that bolsters resilience at low cost. The absence …

The Ability Of Berry Extracts To Inhibit Alpha-Glucosidase In Vitro, Shannon Dubois

Honors College

Type 2 diabetes is a growing public health concern. Drugs, such as acarbose, are used to slow the rise in blood glucose levels after meals by inhibiting the enzyme, alphaglucosidase, which is responsible for digesting complex carbohydrates. The objective of this study is to compare the alpha-glucosidase inhibitory activity of extracts from Maine blueberries and blackberries to acarbose because these plants are very anthocyanin-rich. Varietal differences in highbush blueberries (Vaccinium corymbosum) and agricultural practices for growing wild or lowbush blueberries (Vaccinium angustifolium Ait.) are also experimental variables. The twelve berry samples were obtained from farms around the state of Maine …

A Study Of Cooking And Varietal Effects On Potato In Vitro Bile Acid Binding Capacity, Emily Hinkle

Honors College

Potatoes have received negative press about being unhealthy due to having high starch content, but these vegetables contain many healthful components. Many compounds in food, such as soluble dietary fiber, help reduce serum cholesterol levels by binding to bile acids in the digestive tract and causing the body to draw from serum cholesterol to create new bile acids. Potatoes were prepared three different ways (raw, steamed, steamed then cooled) and different varieties of potatoes were used, each with different chemical compositions (King Harry, Elba, Yukon Gold and All-Blue). The potatoes were subjected to an in vitro digestion to simulate the …
