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. …

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.

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

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 …

Starch-Pectin Matrices For Encapsulation Of Ascorbic Acid, Yiwei Liu

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Starch and pectin are two food-grade carbohydrates widely utilized in the food industry. Starch and pectin polymers have been investigated in encapsulating functional food ingredients and in pharmaceutical applications. Resistance to enzyme hydrolysis, differential solubilities, depending on the pH, and the ability to ‘protect’ unstable molecules are considered some of the beneficial properties of starch and pectin polymers, for encapsulation applications. Food ingredients could be delivered in a controlled manner to a specific target by encapsulating in micro-scale particles, i. e., microencapsulation. Two studies were conducted to investigate the ability of selected starch-pectin blends in microencapsulating ascorbic acid (vitamin C) …
