Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford Oct 2016

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford

STAR Program Research Presentations

Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that …


Reducing Food And Packaging Waste Through Developing Edible Fruit Based Packaging Prototypes, Melanie Thatcher Jun 2016

Reducing Food And Packaging Waste Through Developing Edible Fruit Based Packaging Prototypes, Melanie Thatcher

Materials Engineering

Packaging is used to contain, preserve, protect, and advertise both manufactured and natural products. In 2013 it was reported that over thirty percent of solid waste in the United States was from packaging. One way to reduce the impact of packaging on the environment is to create a solution that is edible and sourced from a waste or secondary food product that is not currently being utilized. Food-contact packaging made from recycled materials must meet strict U.S. Food and Drug Administration (FDA) regulations to be utilized as raw material for packaging. Fruit pomace is a candidate material since it may …


The Use Of Lactic Acid Bacteria To Control The Growth Of Foodborne Pathogens On Fresh-Cut Fruits And Sprout Vegetables, Franca Gabriela Rossi Jun 2016

The Use Of Lactic Acid Bacteria To Control The Growth Of Foodborne Pathogens On Fresh-Cut Fruits And Sprout Vegetables, Franca Gabriela Rossi

Master's Theses

Growing consumer awareness of the health benefits associated with fruits and vegetables and demand for easy to prepare products has prompted the development of a wide variety of minimally processed fruits and vegetables. Minimally processed fruits and vegetables are often peeled, cut, or diced which compromise the produces’ natural protective barriers, exposing a nutrient rich medium and providing an ideal environment for the growth of microorganisms, including foodborne pathogens. The germination conditions of sprout vegetables consisting of relatively high temperatures and humidity, low light and abundance of nutrients are also conducive to the proliferation of foodborne pathogens. Recent outbreaks and …


Effect Of Reduced Sodium Cheese On The Growth Of Pathogenic Bacteria And Inactivation Of Listeria Innocua Using Supercritical Fluid Extraction With Co2, Suyapa Padilla Antunez Apr 2016

Effect Of Reduced Sodium Cheese On The Growth Of Pathogenic Bacteria And Inactivation Of Listeria Innocua Using Supercritical Fluid Extraction With Co2, Suyapa Padilla Antunez

Master's Theses

Listeria monocytogenes continues to challenge the dairy industry in causing post-process contamination of cheeses. To reduce risk of contamination, it is crucial to understand the growth and survival of pathogenic bacteria in cheese products and to develop post-process mitigation strategies. This study evaluated the fate of pathogens in reduced and regular sodium Mozzarella cheese, and the potential of Supercritical Fluid Extraction with CO2 (SFE) to reduce Listeria innocua on Mozzarella and Queso Fresco. The survival of L. monocytogenes, Salmonella, and E.coli O157:H7 (2-3 log CFU/g) in reduced sodium Mozzarella (1.62%), compared to regular sodium Mozzarella cheese (2.15%) …
