Eating Some Invasive Species Could Help To Mitigate The Impacts Of Climate Change-Related Invasions, And May Increase Future Food Security, Jesse Bull Saffeir

Independent Study Project (ISP) Collection

Climate change is predicted to increase the spread and abundance of invasive species and to erode global food security. I hypothesized that by incorporating edible invasive species into local food sheds, these two problems could help to mitigate each other. I set out to answer two questions: could eating invasive species reduce their spread and abundance? And could eating invasive species minimize the impacts of climate-change related food shocks? To answer these questions, I surveyed the existing literature on human consumption of invasive species, created a list of criteria that make an invasive species suitable for management through human consumption, …

The Disparity Between Scientific Consensus And American Public Opinion Of Genetically Modified Organisms And Genetic Engineering, Matthew A. Cherubino

Student Publications

Genetically modified organisms (GMOs) and genetic engineering (GE) are accepted as safe and useful by the consensus of the scientific community. Their diverse utility has shown promise in addressing major challenges of the 21st century, including world hunger, global warming, and the prevalence of diet-related diseases (e.g. heart disease, cancer, diabetes, etc.). A 2014 Pew Research Center survey revealed that while 88% of scientists agreed that GM foods were safe to eat, only 37% of American consumers agreed. Furthermore, only 35% of U.S. adults trusted scientists to accurately inform the public about GMOs. To explain this disparity, I synthesize information …

Encapsulation Of Astaxanthin-Enriched Camelina Seed Oil Obtained By Ethanol-Modified Supercritical Carbon Dioxide Extraction, Liyang Xie

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Astaxanthin is a high-value carotenoid widely used in the food, feed, nutraceutical, and pharmaceutical industries. Natural sources of astaxanthin are preferable to synthetic sources. However, current sources of natural astaxanthin are limited and fall short of global demand. In addition, effective extraction and stabilization strategies are needed before the utilization of natural astaxanthin in food applications. This work investigated 1) the feasibility of ethanol-modified supercritical carbon dioxide (SC-CO2) extraction of astaxanthin from engineered camelina seed, a potential source of natural astaxanthin, and 2) the potential of an emulsion-based system to protect astaxanthin after extraction. The physical properties of the emulsion …
