Investigating The Utilization Of Mushrooms In Beef-Based Products For Improved Health, Kristin Wong 2017 University of Massachusetts Amherst

Investigating The Utilization Of Mushrooms In Beef-Based Products For Improved Health, Kristin Wong

Masters Theses

This research investigated the use of mushrooms in beef-based products as a means to reduce overall sodium and fat for food service applications. Initial product development used physical characterization analysis (color, moisture, texture, yield, fat, and sodium) to determine initial threshold of mushroom inclusion with minimal differences against an all-meat control. Additional physical analysis then investigated a variety of other factors (mushroom type, blanching, mushroom particle size, salt level, and meat/fat blend) to determine if there were other attributing ingredient characteristics that would yield statistical similarity to the all-meat control. Taco filling formulations with optimized ingredients were then fielded ...

Two flexible food packaging barrier material film structures were employed for this research study to evaluate the effects of over-the-road truck transport. The films containing different barrier materials, ethylene-vinyl alcohol (EVOH) or aluminum oxide (AlOx), were selected based on their abundant use within the flexible food packaging arena. Pouches were formed and filled with tomato paste before being thermally processed then palletized for shipment. Pouches were shipped over-the-road via truck transport a distance of 2,500 miles. After transport, the oxygen transmission rate (OTR) of the pouches located on the bottom and top layers of the palletized loads were obtained ...


Edible Insects As A Source Of Food Allergens, Lee Palmer 2016 University of Nebraska-Lincoln

Edible Insects As A Source Of Food Allergens, Lee Palmer

Dissertations, Theses, & Student Research in Food Science and Technology

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 ...

Professional Agricultural Workers Journal

Abstract

Interest in local and regional food production has been growing in the last few years. The study, therefore, assessed consumer attitudes and beliefs regarding local or regional livestock products. Data were obtained from a convenience sample of 384 participants from several counties of Georgia, and were analyzed by descriptive statistics, including chi-square tests. A majority of respondents thought using chemicals and additives in locally or regionally produced beef or goat meat was a serious or somewhat serious hazard. 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 2016 K-State Confucious Institute

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 2016 University of Montana, Missoula

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

STAR (STEM Teacher and Researcher) 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 2016 SIT Study Abroad

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 ...


Local, Organic, Inexpensive And Safe: Can Large Retailers Do It All?, Henry An, Sebastien Pouliot, Richard Volpe 2016 University of Alberta

Local, Organic, Inexpensive And Safe: Can Large Retailers Do It All?, Henry An, Sebastien Pouliot, Richard Volpe

Sebastien Pouliot

One of the most important changes in the food industry in recent decades has been the increase in retailer concentration at the national level. The trade publication Progressive Grocer releases the Super 50 annually, a ranking of the 50 largest food retailers in the U.S., by receipts. In 1997 the top 5 retailers controlled 24 percent of the national market. By 2004 this figure was 46 percent and by 2010, 61 percent.1 Much of this change has been driven by waves of mergers and acquisitions (Franklin, 2001), but it is impossible to overlook the role that big box ...


Welfare Effects Of Mandatory Traceability When Firms Are Heterogeneous, Sebastien Pouliot 2016 Iowa State University

Welfare Effects Of Mandatory Traceability When Firms Are Heterogeneous, Sebastien Pouliot

Sebastien Pouliot

We develop a framework in which the cost of producing a quantity food and the cost of food safety differs across firms. We show that large firms may supply the safest food even though small firms have a cost advantage in producing safe food. The model shows that mandatory traceability can decrease the overall safety of food when small firms that supply the safest food exit the industry. Our model applies to food safety but can be applied to a wide range of issues related to regulation and product quality.


Consumer Confidence In Food Safety And The 2010 Egg Recall, Sebastien Pouliot 2016 Iowa State University

Consumer Confidence In Food Safety And The 2010 Egg Recall, Sebastien Pouliot

Sebastien Pouliot

Iowa egg producers recalled nearly 500 million eggs in August 2010. The typical effect of a recall is to cause a decline in the demand for the affected product, yielding a decrease in the price. In the case of August 2010 egg recall, the price of eggs increased in the following weeks. This essay investigates the market effects of the egg recall. I estimate a system of simultaneous equations that includes supply and demand equations for the two main segments of the US industry. This essay offers preliminary evidence of the market effects of the August 2010 egg recall and ...


Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li 2016 University of Houston

Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li

Peter J. Li, Ph.D.

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 ...
