Development, Implementation, And Validation Of The Health Density Vending Machine Audit Tool (Hdvmat), Melissa Matthews

Theses - ALL

Vending machines may be contributing to the obesogenic food environment. The Health Density Vending Machine Audit Tool (HDVMAT) was developed to comprehensively evaluate and score vending machines based on machine accessibility, product healthfulness, price, and promotion. A novel nutrient-dense scoring system was created to determine the healthfulness of vended snacks based upon calories and macro/micro-nutrients and of beverages based on type and/or calories. The HDVMAT was implemented in snack and beverage university machines in different states. Nutrition Environment Measures Survey-Vending (NEMS-V) was used to validate the nutrient-density score. Significant differences in HDVMAT snack and beverage scores were found between states. …

Lamb Bacon: How The Method Of Brine Distribution And Addition Of A Dry Rub Influences Yields, Morgan Metheny

Animal Science

This study was conducted to test the whether lamb breasts can substitute as the raw material in producing a bacon product. Due to the difference in fat saturation between pork and lamb, this research was used to test how successful lamb absorbs the brine in order to make bacon. The yield results of two different processing techniques, injection and tumbling, were compared along with comparing the affect of adding a dry rub of seasonings to the lamb surface. The 120 lambs breasts were split into four groups of 30. Each group received a different treatment: plain tumbled, plain injected, seasoned …

Mexican Cuisine - From The Maya To Mcdonalds, Irving W. Levinson

History Faculty Publications

The food a people place on their tables tells us much about their history and their culture. In México, we have two very different traditions of cooking that came together gradually during the past hundred or so years. The traditions were those of the Spaniards on the one hand and of the Indians and mestizos who comprised the majority of Mexicans during the colonial era.

Detection Of Pahs In Commercial And Wild Caught Fish Oil Using Scanning Fluorescence Spectroscopy, Edwin Antonio Pena

Seton Hall University Dissertations and Theses (ETDs)

The DeepWater Horizon (DWH) oil spill contaminated a large area in the Gulf of Mexico in summer 2010. It is likely that many aquatic species in the Gulf were affected by the spill. Crude oil contains polycyclic aromatic hydrocarbon (PAHs). Some PAHs are carcinogenic to fish and humans. The purpose of this project was to develop menhaden fish oil as a biomonitoring tool for crude oil contaminants such as PAHs using scanning fluorescence spectroscopy (SFS). Menhaden (Genus Brevoortia) is one of the most ecologically and economically important marine fish species along the Atlantic and Gulf coast; however, it is …

Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell

National Invasive Species Council

Conclusion

The success of any harvest incentive program to address aquatic invasive species will depend upon numerous biological, socioeconomic, and legal considerations. Programs that encourage harvest may be a successful management tool in targeting small, distinct populations; in high priority areas within a larger invasion; or they may play a supplementary role within larger control programs. Their use, however, will require careful review, planning, and monitoring to ensure success and that they do not unintentionally lead to further spread of invasive species, cause additional harm to native species, or waste valuable resources.

Candy Flavorings In Tobacco, Jessica E. Brown, Wentai Luo, Lorne M. Isabelle, James F. Pankow

Chemistry Faculty Publications and Presentations

Professor James F. Pankow reveals striking similarities between the patterns in the flavoring chemicals used in flavored tobacco products and those in popular candy and Kool-Aid products. The authors analyzed 12 artificially flavored candy and fruit drink products and compared them to 15 widely-available flavored tobacco products. They found significant overlap in the chemical signatures of the flavor chemicals. Several of the tobacco products contained flavor chemicals at much higher concentrations than in the non-tobacco products.

Characterizing And Improving The Oral Sensations And Preference Of Polyphenol-Rich Aronia Berry Juice, Jeeha Park

Honors Scholar Theses

Background: Aronia berries (chokeberries) have very high levels of health-promoting polyphenols yet cause "choking" sensations due to bitterness and astringency. We aimed to describe oral sensations and palatability of aronia juice by variations in harvest time and oral sensory phenotype. Sensory blocking combinations were tested to improve juice acceptability. Methods: Ripe aronia berries were harvested at 7 time points and juiced for oral sampling by 50 adults who underwent bitter taste phenotyping. The adults reported quality intensities of prototypical tastes, foods, and aronia juices. Ethyl butyrate (10ppm) and/or sucrose (0.15 and 0.3M) were added to prototypical oral stimuli and aronia …

Investigating Antibiotic Resistance Levels Of Salmonella Internalized In Lettuce Leaves, Jason B. Thomas

McNair Scholars Research Journal

An Evaluation Of The East Indianapolis Food Desert, Angelina Qin

Undergraduate Honors Thesis Collection

The Indy East Food Desert (IEFD) appears to suffer from many common conditions noted by various scholars as food desert identifiers. Yet, its situation still remains unique. Though there is a prevalence of minority populations, low-income households, and low-education attainment levels, there are also factors of low-access, poor food options (within the limited food outlets in the neighborhoods), and poor eating habits which shape the situation of the community. In an attempt to alleviate the food desert problems, the Indy East Food Desert Coalition (IEFDC) was formed. IEFDC partnered with Butler University's Center for Urban Ecology in order to assess …

Analysis Of Volatile Compounds And Their Changes During Liquor Aging Of Chinese Liquor 'Gujing Gongjiu', Qingchuan Liu

All Theses

Chinese liquor 'Gujing Gongjiu' is a traditional Chinese distilled alcoholic beverage that is categorized into a strong-aromatic fragrance liquor. It has a strong mixed floral, fruity, and sweet flavor with a smooth taste. Volatile compounds were extracted by headspace solid-phase microextraction (HS-SPME) from Gujing liquors that were aged for 1, 5, 10, and 20 years. Optimization of HS-SPME method was performed to determine the best experimental condition for extraction of liquor volatiles. Gas chromatography-mass spectrometry (GC-MS) was used for quantitative and qualitative analysis of liquor volatiles. Volatile compounds were identified by Kovat's retention indices and their mass spectrum. The influence …

Effect Of Bromelain On Duck Breast Meat Tenderization, Ahmet Buyukyavuz

All Theses

ABSTRACT This study was conducted to determine the effect of bromelain on duck breast meat tenderization. Duck breasts were marinated with different concentrations (0, 1.5, 3 and 4.5%; C2, B1.5, B3 and B4.5, respectively) of bromelain and a solution composed of 92% refrigerated water, 6% salt and 2% sodium tripolyphosphate by using a vacuum food tumbler machine. A second non-marinated control (C1) was also included. Marination tumbling was operated at 8 RPM for 8 minutes. Physico-chemical and quality parameters were determined on raw and cooked samples. A significant reduction (p<0.05) in pH was observed in all bromelain treated samples when compared to C2. Although there was a significant reduction in pH of B1.5 when compared to C1, there was no significant difference among B3, B4.5 and C1. A significant increase was observed in water holding capacity of B3 and B4.5 when compared to C1. While a significant reduction was observed in lightness (L*), no differences were observed in redness (a*) and yellowness (b*) values of marinated samples (C2, B1.5, B3 and B4.5) when compared to C1. However, a significant increase in lightness (L*), and a significant decrease in redness (a*) and yellowness (b*) were observed in cooked bromelain treated samples. No differences were observed in razor shear forces, moisture content and water activity between treatments. There was no significant difference in cook yield of all marinated samples (C2, B1.5, B3, and B4) when compared to the C1. A significant reduction (p<0.05) in Warner-Bratzler shear force values was observed in all marinated samples when compared to untreated control (C1). Based on results, use of bromelain in marination solutions under the conditions tested here would not be cost effective.
