Separation And Characterization Of Reconstituted Skim Milk Powder Treated With Mineral Chelators, Amy Kringle

Master's Theses

The proteins found in milk are largely important in the functionality of many dairy products and dairy processes. The casein micelle system in milk is a complex and highly studied system. The micelle is thought to be a sponge like structure containing four caseins, α_s1, α_s2, β, and κ casein, and bound together with colloidal calcium phosphate. When a chelating agent such as a citrate, phosphate, or polyphosphate are added to milk systems, the CCP is bound to the chelator and removed from the micelle. It has been shown through past research that the use of …

Effect Of Lactose Source, Lactose Level, And Type Of Emulsifying Salts On The Properties Of A Processed Cheese Product, Gabrielle Alyss Gunter

Master's Theses

Previous studies on the use of nonfat dry milk, whey protein concentrate 34 and lactose powders in processed cheeses or cheese analogs found that increasing the percentage of lactose was associated with an increase in browning and crystallization. There has been little work done of the effects of lactose in processed cheese functionality. Therefore, the objective of this research is to build on and understand the effects of lactose from by three commercially produced dairy powders (nonfat dry milk (NFDM), whey protein concentrate 34 (WPC), lactose) and two different emulsifying salts on properties of processed cheese. Processed cheeses were made …

Building An Assessment-Focused Information Literacy Program For Agriculture And Related Disciplines: A Collaborative Approach, Katherine O'Clair

Library Scholarship

Students pursuing degrees in STEM fields, including agriculture and related sciences, need to develop discipline-specific information skills in order to be successful in their educational pursuits and to meet tomorrow’s challenges in their future work as agriculture professionals. Oftentimes, information literacy programs are situated in general education or liberal arts courses, leaving the discipline-specific courses to incorporate information literacy only when and where possible. As STEM librarians, we know this is not sufficient, but the challenge of building a STEM-specific information literacy program can be overwhelming, especially when instructors have little time to incorporate any additional content into their already-packed …

Nutrition And Health-Related Quality Of Life In Older Adults In The Us, Nhanes 2009–2012, Jessica Anne Hews

Master's Theses

Few studies have investigated the relationship between diet quality and health-related quality of life (HRQOL), especially in the older adult population that is most at risk for poor diet and health. Self-perceived HRQOL is a more powerful predictor of morbidity and mortality than objective measures of health. The aim of this thesis was to examine the association between nutrition-related factors (especially diet quality) and HRQOL in community-dwelling older adults aged 60 and above. This research used cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2009-2010 and 2011-2012 cycles to select and include diet quality variables, meal-related variables, …

Common Arguments For The Moral Acceptability Of Eating Meat: A Discussion For Students, Dan Lowe

Between the Species

This paper is a teaching tool which instructors of animal ethics may assign to students to help them evaluate those students’ most frequent arguments for the moral acceptability of eating meat. Specifically, the paper examines (and finds inadequate) the arguments that eating meat is morally acceptable because it is (1) historically widespread, (2) necessary, and (3) natural. The aim of discussing these arguments is to pave the way for a more fruitful and focused discussion of the canonical texts of the animal ethics literature.

The Commonsense Case For Ethical Vegetarianism, Mylan Engel Jr.

Between the Species

The article defends ethical vegetarianism, which, for present purposes, is stipulatively taken to be the view that it is morally wrong to eat animals when equally nutritious plant-based foods are available. Several examples are introduced (i) to show that we all agree that animals deserve some direct moral consideration and (ii) to help identify and clarify several commonsense moral principles—principles we all accept. These principles are then used to argue that eating animals is morally wrong. Since you no doubt accept these principles, the argument demonstrates that consistency with your own beliefs and values commits you to the …

Review Of Slaves Of Our Affection: The Myth Of The Happy Pet, Katherine Allen

Between the Species

This article reviews Charles Danten’s Slaves of Our Affection: the Myth of the Happy Pet, outlining and evaluating Danten’s arguments for the abolition of the pet trade. The review delineates Danten’s main points; that the commodification of companion animals is antithetical to their welfare, that veterinarians, pet food manufacturers and breeders serve the dictates of the economic bottom line rather than the interests of animals, and that the majority of pet owners, while well-intentioned, are ill-equipped to meet the physiological and psychological needs of their animal companions.

The reviewer asserts that Danten’s arguments are generally successful, but suggests that …

Digestibility Of Two Complete Pelleted Diets By The Horse (Equus Caballus) As A Model Animal For Nondomestic Hindgut Fermenters, Emily M. Schwartz

Master's Theses

Estimating nutrient and energy requirements of exotic animals is a necessary component of nutrition management in zoos and other wildlife facilities. In the absence of species-specific data, domestic animal models are often referenced. Herbivorous hindgut fermenters, such as horses, zebra, and rhinoceros, rely on microbial fermentation in the cecum and colon to utilize dietary structural carbohydrates. The study objective was to measure the digestible energy of two (LOW, HIGH) complete pelleted diets by the horse as a model for nondomestic hindgut fermenters. Seven, individually housed, adult Quarter Horse (Equus caballus) geldings were assigned to one of two diets as 100% …

Predicting Invasive Range Of Eucalyptus Globulus In California, Anthony J. Lopez

Master's Theses

Eucalyptus globulus is the subject of intense debate in California. Its invasive potential, aggressive growth, reproductive biology, and association with fire make the prediction of spread important in California. Two modeling simulations, Climex and Maxent, will illustrate the distribution and potential growth range of E. globulus in California based on climate and presence. Modeling the potential range of growth will predict invasive spread. The anticipated result is the continued spread of E. globulus in coastal regions with adequate moisture and suitable climate.

Fruit And Vegetable Consumption Of College Students: What Is The Role Of Food Culture?, Christiane Schroeter, Lisa A. House

Agribusiness

Our primary objective is to assess the role of culture by linking college students’ current consumption of fruits and vegetables with their produce consumption levels while with family. Using a Tobit model, we analyzed data from an online survey with college students. Family consumption of fruits was highly predictive of the individual’s consumption of fruits. For each unit increase in the reported consumption of fruits (vegetables) with the family, the respondents’ fruit (vegetable) consumption at school increased by 0.65 (0.30) units compared to the base consumption level of 1.95 (1.82) times of fruit intake per day.
