Ethically Sourced Vanilla: Certifications In The Production Of Vanilla In The Sava Region Of Madagascar, Maisie Campbell

Independent Study Project (ISP) Collection

Vanilla is an orchid whose beans are harvested after ten months on the vine. About eighty percent of the world’s vanilla is produced in Madagascar and the SAVA region is the capital of vanilla production within the country. The changing demand of vanilla, damage from cyclones, and the three-year development of the vanilla plants before they begin producing beans causes a boom and bust cycle of prices of vanilla. Some organizations have tried to ameliorate the problems these cycles and low prices pose to vanilla farmers by creating certifications for companies that promise that they will not pay less than …

The Slow Food Movement: A 'Big Tent' Ideology, Mark N. Wexler, Judy Oberlander, Arjun Shankar

Journal of Ideology

The Slow Food Movement (SFM) has been characterized as a reminder of the centrality of the kitchen in the “good old days”. It has also been referred to as a poor use of science posing as a rallying point for the beleaguered middle class trying to reclaim psychological territory lost to the fast-paced commercialization of what was once private or leisure time. This paper argues that both these criticisms contain more than a kernel of truth. However, each misses the mark when it comes to explaining the relative successes of SFM. In this paper, we explore SFM’s basic ideological premises. …

Over 30% of adults in the U.S. are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) rather than carbohydrate (CHO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n = 4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in a randomized, crossover design study with a one-week washout period (time between the administration …

Effect Of Applied Magnetic Field On Surface Morphology, Optical And Electrical Property Of Tin (Iv) Oxide (Sno2) Nanomaterial For Meat Spoilage Detection, Gil Nonato Santos, Mary Gillian Santos, Jonathan C. Briones, Michael P. Delmo, Eriberta B. Nepumuceno, Joshua Miguel C. Danac

Angelo King Institute for Economic and Business Studies (AKI)

The specter of botcha or “double dead” meat is a persistent, if not underestimated, threat in Filipino markets. In 2014, the National Meat Inspection Service (NMIS) recorded the confiscation of more than 12 metric tons of so-called hot meat, unfit for human consumption. The hazard that consuming this and other forms of spoiled meat poses to human health cannot be overstated, especially because spoiled meat can harbor dangerous pathogens or parasites such as Salmonella, Staphylococcus, Pseudomonas Aeroginosa, and Trichinella.

Let's Stop Worrying And Learn To Love Transparency: Food And Technology In The Information Age, Scarlettah Schaefer

Journal of Food Law & Policy

Food and technology have had a long and tempestuous relationship. Current methods of food production and processing in the industrialized world depend heavily on technological developments. However, all technologies are not created equal. Some can produce food that is safer, more sustainable, more nutritious, or longer lasting. Some can have the opposite effect: increasing opportunities for adulteration, increasing the difficulty in detecting food fraud, and contributing to both foreseeable and unforeseeable health or ecological costs. Increasingly sophisticated technologies often become less apparent to the average consumer. For example, consider irradiated meat or genetically modified foods as opposed to freezer storage …

Acanthamoeba Spp. As Reservoirs For Transmission Of Norovirus, Tun-Yun Hsueh

Graduate Theses and Dissertations

Human noroviruses (HuNoV) are the most common cause of foodborne disease outbreaks in the United States and the most common food commodities implicated in HuNoV outbreaks are leafy greens; however, the vehicle of transmission and point of contamination are often unknown. Here, we hypothesize that common free-living amoebae (FLA) ubiquitous in the environment may act as reservoirs of HuNoV and facilitate the transmission of these pathogens to fresh produce. The objective of this research was to first evaluate the interaction/association between HuNoV surrogates and Acanthamoeba by incubating them together and analyzing virus titer associated with amoeba through an 8 day …

College Students’ Perceptions Regarding Sensory Aspects Of Conventionally Produced And Unconventionally Produced Foods: Implications For Marketing To The Millennial Generation, Christina Crowder, Catherine W. Shoulders, K. Jill Rucker

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Consumers vote every day on which products line the shelves of grocery stores, co-ops, and niche markets. Public unrest with regard to the environmental, animal welfare, food purity, and human health impacts of agricultural production practices have led to the rise of unconventionally produced (UP) food products. While the sales of UP foods is increasing, studies regarding the qualities of such products that impact consumer purchases have yielded inconsistent results. This study examined students’ perceptions of sensory aspects of conventionally produced (CP) and UP foods to better understand how sensory aspects impact decisions to purchase. Students reported consistent perceptions regarding …

Cloned Meat, Voluntary Food Labeling, And Organic Oreos, Donna M. Byrne

The University of New Hampshire Law Review

[Excerpt] “In December 2006, the Food and Drug Administration (FDA) announced that it had reviewed all the available evidence and was poised to approve meat and milk from cloned animals and their progeny. I remember telling one of my colleagues, a patent law professor, who should be as comfortable with technology as anyone, about this development, and his response was, “Yuck. I’m not eating it!” To which of course I replied, “Humph. You won’t know the difference.” Meat or milk from a clone or its descendant is virtually identical to meat or milk from a non-clone, said the FDA, as …

Drying Of Post-Harvest Rough Rice With Silica Gel: A Preliminary Investigation, Stephen J. O'Brien, Terry J. Siebenmorgen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Rice drying operations can encounter problems of over drying and losses in head rice yield (HRY) through the formation of fissures. Typical rice drying methods also utilize large volumes of expensive fossil fuels to dry the kernels. Drying of rice with a solid desiccant such as silica gel has several potential advantages that avoid some of these problems. Two cultivars of long-grain rough rice, ‘Cheniere’ and ‘Wells’ with harvest moisture contents of 17.8% and 22.0%, respectively, were dried over a 48-h period with various ratios of rough rice-to-silica gel. It was found that an intimate mixture of 3:1 rough rice …
