Edible Insects As A Source Of Food Allergens, Lee Palmer
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Increasing global population increasingly limited by resources has spurred interest in novel food sources. Insects may be an alternative food source in the near future, but consideration of insects as a food requires scrutiny due to risk of allergens. Currently, the insect Dactylopius coccus, known as cochineal, is used to produce carmine, a natural red pigment used in food, which has caused allergic reactions. This study investigated allergens of cochineal focusing on purification from the pigment. Mass spectrometry identified a previously described major allergen of cochineal and a tropomyosin, although further work is required.
Tropomyosin is a major cross-reactive allergen …

Consequently, many were willing to pay more for meat certified as locally or regionally produced. Furthermore, a majority agreed or strongly …
Improve Food Safety Of Chinese Restaurants In Kansas Through Multicultural Intervening Measures, Shijun Yan, Autumn Schuck
Improve Food Safety Of Chinese Restaurants In Kansas Through Multicultural Intervening Measures, Shijun Yan, Autumn Schuck
Institute for Student Learning Assessment
Chinese restaurants' food safety problems have attracted the attention of food safety regulators. According to the many feedback of the state food safety inspectors, there are more problems in the operations of Chinese restaurants than in those others. The probability of repeating the same mistakes is also high in the review of the violation items in the inspection reports. Due to the number of violating behaviors in Chinese restaurants, food safety inspectors have to do many follow-up inspections, and this causes much waste of human resources.
The purpose of this study was to enable Chinese restaurant practitioners to understand US …

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 …
What Is The Taste Of Co2? The Sustainability Of Icelandic Food Systems In The Face Of Climate Change, Molly Peek
What Is The Taste Of Co2? The Sustainability Of Icelandic Food Systems In The Face Of Climate Change, Molly Peek
Independent Study Project (ISP) Collection
Food security in the arctic and subarctic is an area of growing research and concern as climate change continues to alter the availability of traditional foods eaten in remote areas, especially as shipping food has questionable sustainability and contributes to rising CO2 levels. Previous research has noted changes in the Icelandic diet making it more reliant on foreign imports, although there is still strong localized agriculture. Because of its geothermal activity, Iceland has a unique advantage over other highlatitude countries in growing food with a minimal carbon footprint, although that potential is unequal throughout the country. This study utilized available …

Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li
Peter J. Li, PhD
Developmental states are criticized for rapid “industrialization without enlightenment.” In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. The enthusiastic response of the livestock industry to the many state policy incentives has made China the world’s biggest animal farming nation. Shortage of meat and dairy supply is history. Yet, the Chinese government is facing new challenges of no less a threat to political …
Particular Applications Of Food Irradiation Fresh Produce, Anuradha Prakash
Particular Applications Of Food Irradiation Fresh Produce, Anuradha Prakash
Food Science Faculty Articles and Research
On fresh fruits and vegetables, irradiation at low and medium dose levels can effectively reduce microbial counts which can enhance safety, inhibit sprouting to extend shelf-life, and eliminate or sterilize insect pests which can serve to facilitate trade between countries. At the dose levels used for these purposes, the impact on quality is negligible. Despite the fact that regulations in many countries allow the use of irradiation for fresh produce, the technology remains under-utilized, even in the light of an increase in produce related disease outbreaks and the economic benefits of extended shelflife and reduced food waste. Putative concerns about …

Reducing Food And Packaging Waste Through Developing Edible Fruit Based Packaging Prototypes, Melanie Thatcher
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 Food Industry’S Perception Of Economically Motivated Adulteration And Related Risk Factors, Lindsay Colleen Murphy
Masters Theses
The United States of America has numerous safeguards in place to protect our food supply, including federal regulations and the food and beverage industry’s dedication to food safety. One of the issues that the food and beverage industry continuously battles is the prevalence of intentional adulteration. The Food Safety Modernization Act (FSMA) specifically addresses intentional adulteration and its sub-category of economically motivated adulteration (EMA) by requiring all facilities that supply food to the US to assess the vulnerabilities within their operation in order to prevent events that could cause public harm. The purposes of this study are threefold: (1) to …
Odor-Induced Taste Modifications In Teas, Rachel Elizabeth Isaacs
Odor-Induced Taste Modifications In Teas, Rachel Elizabeth Isaacs
Masters Theses
Although odorants and tastants are perceived by two different sensory modalities, the perceived taste qualities of a solution may be modified with the addition of an odorant. While many studies have investigated odor-induced taste modifications in model solutions, there is a lack of conducted research examining odor-induced taste modifications in complex food systems. The research objective was to determine the effect of added vapor-phase stimuli on the perceived sweetness of a model solution and complex food system.
Eight vapor-phase stimuli (i.e. blueberry, caramel, ginger, honey, lemon, orange, peach, and strawberry) were selected for investigation. The study was conducted in two …
