Consumers' Evaluations Of Genetically Modified Food Messages, Taylor K. Ruth, Joy N. Rumble 2019 University of Illinois at Urbana-Champaign

Consumers' Evaluations Of Genetically Modified Food Messages, Taylor K. Ruth, Joy N. Rumble

Journal of Applied Communications

Consumers are concerned about the risks related to genetically modified (GM) food, and there is a need for agricultural communicators and educators to address those concerns. The purpose of this study was to explore Florida residents’ latitudes of acceptance, rejection, and noncommitment toward GM food messages. The findings from this study can be used to guide communication and education campaigns for GM food. An online survey was distributed to a non-probability sample of 500 Florida residents to fulfill the purpose of the study. The messages that most aligned with the respondents’ views toward GM food discussed how potential risks related ...


Healthy Skepticism: The Relationship Between Funding Source And Conclusion In Nutrition-Related Scientific Articles On Saturated Fat, Lili Muskal 2019 Claremont McKenna College

Healthy Skepticism: The Relationship Between Funding Source And Conclusion In Nutrition-Related Scientific Articles On Saturated Fat, Lili Muskal

CMC Senior Theses

Recently published scientific articles have led to mixed nutritional advice on dietary saturated fatty acids. Lesser et. al (2007) identified that mixed conclusions in scientific articles on sweetened beverages might be attributed industry funding, as articles funded by the beverage industry are four to eight times more likely to report conclusions in favor of the sponsor’s products. This thesis applies Lesser’s methods to determine whether industry funding influences the inconsistent conclusions on saturated fatty acids. This thesis analyzes 100 articles on foods high in dietary saturated fatty acids. While studies with food industry funding are more likely to ...

Influence Of Shipping Container Upon Temperature, Relative Humidity, And Bacterial Growth On Broccoli, Nicholas Berus

Masters Theses

Temperature and relative humidity of produce throughout the cold chain can greatly affect the quality and safety of the food product. Different packaging systems or containers can provide better cooling environments for food products that could decrease temperature abuse and ultimately safety risks. In this study we compiled temperature and relative humidity profiles of broccoli packed in different shipping containers throughout the produce supply chain. The shipping containers looked at were the wax corrugated box, reusable plastic containers (RPC), and Eco Pack Green Box with and without a lid. Large differences were seen in the temperature profiles of each package ...


Dry Bean Preferences And Attitudes Among Midwest Hispanic And Non-Hispanic White Women, Donna M. Winham, Megan E. Tisue, Shelly M. Palmer, Karen A. Cichy, Mack C. Shelley 2019 Iowa State University

Dry Bean Preferences And Attitudes Among Midwest Hispanic And Non-Hispanic White Women, Donna M. Winham, Megan E. Tisue, Shelly M. Palmer, Karen A. Cichy, Mack C. Shelley

Food Science and Human Nutrition Publications

Bean (Phaseolus vulgaris L.) intakes in the United States (US) lag behind dietary recommendations despite their positive nutrition profile, health benefits for reducing chronic disease risk, and inclusion in nutrition assistance programs. Low-income groups, including Hispanics, have an increased risk of cardiovascular disease, type 2 diabetes, obesity, and some cancers. Hispanic dietary quality and bean consumption may decline with increasing acculturation. Intakes at recommended levels could improve health in all vulnerable low-income populations. The study objectives were to describe dry and canned bean preferences, consumption frequency, and attitudes among low-income Hispanic and non-Hispanic white women, and to assess if these ...

Effects Of Harvest Time On The Aroma Of White Wines Made From Cold-Hardy Brianna And Frontenac Gris Grapes Using Headspace Solid-Phase Microextraction And Gas Chromatography-Mass Spectrometry-Olfactometry, Somchai Rice, Madina Tursumbayeva, Matthew Clark, David Greenlee, Murlidhar Dharmadhikari, Anne Fennell, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

The Midwest wine industry has shown a marked increase in growers, hectares planted, wineries, and wine production. This growth coincides with the release of cold-hardy cultivars such as Brianna and Frontenac gris, in 2001 and 2003, respectively. These white grape varieties account for one-third of the total area grown in the state of Iowa. It is generally accepted that the wine aroma profile plays a crucial role in developing a local, sustainable brand. However, the identity of Brianna/Frontenac Gris-based wine aromas and their link to the grape berry chemistry at harvest is unknown. This study aims to preliminarily characterize ...


Evaluation Of Volatile Metabolites Emitted In-Vivo From Cold-Hardy Grapes During Ripening Using Spme And Gc-Ms: A Proof-Of-Concept, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel 2019 Iowa State University

Evaluation Of Volatile Metabolites Emitted In-Vivo From Cold-Hardy Grapes During Ripening Using Spme And Gc-Ms: A Proof-Of-Concept, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

In this research, we propose a novel concept for a non-destructive evaluation of volatiles emitted from ripening grapes using solid-phase microextraction (SPME). This concept is novel to both the traditional vinifera grapes and the cold-hardy cultivars. Our sample models are cold-hardy varieties in the upper Midwest for which many of the basic multiyear grape flavor and wine style data is needed. Non-destructive sampling included a use of polyvinyl fluoride (PVF) chambers temporarily enclosing and concentrating volatiles emitted by a whole cluster of grapes on a vine and a modified 2 mL glass vial for a vacuum-assisted sampling of volatiles from ...

Biogenic Volatiles Emitted From Four Cold-Hardy Grape Cultivars During Ripening, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

In this research dataset, we summarize for the first time volatile organic compounds (VOCs) emitted in vivo from ripening wine grapes. We studied four cold-hardy cultivars grown in the Midwestern U.S.: St. Croix, Frontenac, Marquette, and La Crescent. These cultivars have gained popularity among local growers and winemakers, but still very little is known about their performance compared with long-established V. viniferagrapes. Volatiles were collected using two novel approaches: biogenic emissions from grape clusters on a vine and single grape berries. A third approach was headspace collection of volatiles from crushed grapes. Solid-phase microextraction (SPME) was used to collect ...

Accumulating evidence points to an important role for the gut microbiome in anti-tumor immunity. Here, we show that altered intestinal microbiota contributes to anti-tumor immunity, limiting tumor expansion. Mice lacking the ubiquitin ligase RNF5 exhibit attenuated activation of the unfolded protein response (UPR) components, which coincides with increased expression of inflammasome components, recruitment and activation of dendritic cells and reduced expression of antimicrobial peptides in intestinal epithelial cells. Reduced UPR expression is also seen in murine and human melanoma tumor specimens that responded to immune checkpoint therapy. Co-housing of Rnf5−/− and WT mice abolishes the anti-tumor immunity and tumor inhibition ...

Agricultural and Biosystems Engineering Publications

In this work, for the first time, the volatile organic compound (VOC) emissions from carbonized refuse-derived fuel (CRDF) were quantified on a laboratory scale. The analyzed CRDF was generated from the torrefaction of municipal waste. Headspace solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) was used to identify 84 VOCs, including many that are toxic, e.g., derivatives of benzene or toluene. The highest emissions were measured for nonanal, octanal, and heptanal. The top 10 most emitted VOCs contributed to almost 65% of the total emissions. The VOC mixture emitted from torrefied CRDF differed from that emitted by other types ...

Development Of A Food Safety Training For A Prison Farm: Challenges And Solutions, Angela M. Shaw, Kara Helterbran

Food Science and Human Nutrition Publications

Workers on prison farms in the United States commonly grow produce and row crops and raise livestock. Teaching good agricultural practices to prisoners and prison staff increases the safety of the food produced and reduces the likelihood of an illness outbreak. We developed a food safety curriculum for use on prison farms in Iowa. In developing the curriculum, we encountered many challenges that resulted in modifications in the content and delivery method. We present the content of the curriculum and provide educators with a better understanding of challenges and potential solutions related to working with prison farms.
