Faculty Publications in Food Science and Technology

A prototype on-line acousto-optic tunable filter (AOTF)-based hyperspectral image acquisition system (λ = 450– 900 nm) was developed for tenderness assessment of beef carcasses. Hyperspectral images of ribeye muscle on stationary hanging beef carcasses (n = 338) at 2-day postmortem were acquired in commercial beef slaughter or packing plants. After image acquisition, a strip steak was cut from each carcass, vacuum packaged, aged for 14 days, cooked, and slice shear force tenderness scores were collected by an independent lab. Beef hyperspectral images were mosaicked together and principal component (PC) analysis was conducted to reduce the spectral dimension. Six different textural feature ...

Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang 2015 Clemson University

Determining The Fate Of Non-O157 Shiga Toxin-Producing Escherichia Coli In Dairy Compost During Storage Using The Optimized Detection Method, Hongye Wang

All Theses

Shiga toxin-producing Escherichia coli (STEC), a member of Enterobacteriaceae family, has been recognized as emerging pathogens. Dairy compost is commonly applied to farmland as a soil amendment. Despite the agricultural benefit of manure-based soil amendment, the inadequately treated compost can contribute to fresh produce contamination on the farm. Moreover, the epidemiological results showed that the non-O157 STEC cases have surpassed those of E. coli O157. Therefore, it is critical to evaluate the behavior of non-O157 STEC strains in the dairy manure-based compost. The objectives of this study were to: 1) optimize a culturing method for detecting non-O157 STEC from dairy ...

Hand Hygiene Promotion: An Essential Strategy For Preventing Foodborne Disease In Elementary Schools, Zhangqi Wang 2015 Clemson University

Hand Hygiene Promotion: An Essential Strategy For Preventing Foodborne Disease In Elementary Schools, Zhangqi Wang

All Theses

Student absenteeism is a pervasive problem in the United States, causing a number of educational, economic, and institutional problems. Hand-hygiene interventions have been reported to be a method for reducing illness-associated student absenteeism. As an increasing number of schools offer self-service, including salad bars and bowls of whole fresh fruit, opportunities for the transmission of foodborne pathogens via hands could possibly increase illness-associated student absenteeism. To address this problem, we conducted a two-phase study. First, we conducted a systematic literature review to evaluate peer-reviewed studies (N=24) that reported an association between hand hygiene interventions and illness-associated absenteeism reduction in ...

Self-Learning, Dvd-Based Education Versus Traditional Education Approaches To Improve The Safety Of Warfarin Use Among Patients With Atrial Fibrillation, Jessica Oliver Hatch 2015 Utah State University

Self-Learning, Dvd-Based Education Versus Traditional Education Approaches To Improve The Safety Of Warfarin Use Among Patients With Atrial Fibrillation, Jessica Oliver Hatch

All Graduate Theses and Dissertations

Atrial fibrillation (AF) is a common cardiac arrhythmia that requires extensive medical and pharmaceutical management. The coagulation antagonist warfarin is commonly prescribed to reduce AF-associated stroke. Although warfarin effectively mediates thromboembolitic risk, its management is complex as many factors influence its therapeutic range including: genetics, diet, medication, and herbal and dietary supplement (HDS) interactions. Lack of patient knowledge regarding these factors contributes to poor patient outcomes. With the emerging epidemic of AF, readily available educational tools are necessary to improve patient outcomes while reducing clinician burden.

The purpose of this study was to develop both a self-learning, DVD-based and one-on-one ...


Rolling Harvest Food Rescue, Cathy Snyder 2014 University of Pennsylvania

Rolling Harvest Food Rescue, Cathy Snyder

The Last Food Mile Conference

Rolling Harvest Food Rescue began in 2009 when Founder and Executive Director Cathy Snyder began to volunteer at a food pantry in Hunterdon County, New Jersey. Soon after, a bountiful farmers’ market opened up less than a mile away. Snyder quickly realized that she was able to enjoy the taste and benefits of the market products simply because she had a car and disposable income, a luxury many of the food pantry clients were lacking. Returning to the food pantry the following week, continuing to hand out yet more mac and cheese, high-sodium soups and bruised bananas to struggling, food-insecure ...


All About Leftovers, Jonathan Bloom 2014 University of Pennsylvania

All About Leftovers, Jonathan Bloom

The Last Food Mile Conference

Wasted food is a particularly galling aspect of our broken food system. The juxtaposition of hunger and waste on this planet is both an affront to common sense and morally callous. Food waste is even more appalling when you consider the environmental impact of modern agriculture. Squandering 30 to 40 percent of available calories while 15 percent of American households are food insecure is ethically and ecologically unsustainable.

There is near universal agreement on the scale of the food waste problem, but little accord on what solutions to prioritize. Where shall we push for action on food waste and where ...

Keynote Presentation: Food, Water, And Energy, Robert Giegengack 2014 University of Pennsylvania

Keynote Presentation: Food, Water, And Energy, Robert Giegengack

The Last Food Mile Conference

While blatant food waste late in the production chain is apparent to most of us, less apparent is the inefficiency of resource use in the processes whereby we produce, harvest, process, package, store, and deliver the food that we eat.

We waste water: 72% of water “used” worldwide is applied directly to cropland, much of it via archaic technology. We move water from where it is plentiful to places where we imagine it will be more useful.

We waste nutrients, even those that we know are in limited supply, by careless or excessive application. Effluent from fertilized cropland has contaminated ...

Food Loss And Waste In Distribution: A Retailer’S Perspective, Jihad Rizkallah 2014 University of Pennsylvania

Food Loss And Waste In Distribution: A Retailer’S Perspective, Jihad Rizkallah

The Last Food Mile Conference

Food waste is an expected and inevitable byproduct of any supermarket retailer operation. In the US, the supermarket industry is held to high standards and expected to provide high quality fresh products and make them readily available to consumers during the regular shopping hours and at times, around the clock. These expectations, coupled with the ongoing dilemma of the product shelf life as related to “Best used by XXX date”, or “Sell by XXX date”, along with issues related to efficient packaging have added to the complexity of resolving the food waste problem.

In addition to the waste generated by ...


Study Of A Contemporary Diet In One Household In The Yucatan, Ericka K. Hardin 2014 Western Kentucky University

Study Of A Contemporary Diet In One Household In The Yucatan, Ericka K. Hardin

Honors College Capstone Experience/Thesis Projects

The history of the Yucatan has played a major role in the development of the food system of the area and the nutritional status of the population. Originating from an agricultural based diet, which forms the foundation of the traditional Yucatan diet, there has been a recent shift away from whole and natural foods to a more processed and convenient food supply due to the influx of American products and culture. Coinciding with the influx of these unhealthy foods, there has also been a rise in the health problems of the Mexican population such as heart disease and diabetes, both ...


Improving The Health Impacts Of Whole Grains Through Processing: Resistant Starch, Dietary Fiber Solubility, And Mineral Bioaccessibility, Jennifer A. Arcila Castillo 2014 University of Nebraska-Lincoln

Improving The Health Impacts Of Whole Grains Through Processing: Resistant Starch, Dietary Fiber Solubility, And Mineral Bioaccessibility, Jennifer A. Arcila Castillo

Dissertations & Theses in Food Science and Technology

Whole grains are good sources of starch, dietary fiber, and mineral elements. Starch is an important source of energy but also can be transformed to resistant starch to impart lower caloric value and increase total dietary fiber. Dietary fibers impart physiological benefits to human body once they are fermented by the gut microbiota. Mineral elements are important co-factors of a wide range of enzymes involved for instance in glucose and lipid metabolism. In general human body is capable of absorbing only 21-28% of most mineral elements, and gut bacteria are only able to ferment 34% of the dietary fiber from ...
