Effects Of Uv Filter Pollutants On The Growth Of Cucurbits And Possible Implications For Humans, Leia Staples

Undergraduate Theses

One main area of concern is the use of personal care products and pharmaceuticals in society and their long-term persistence when released into the environment (Chaturvedi et al. 2021). Cucurbits, however, are well-known for taking up pollutants (Namiki et al. 2013, Christou et al. 2019, Komives et al. 2009), so it essential to ensure that these pollutants do not negatively affect growth or productivity of plants. These plants are particularly useful in society because they have many health benefits and are consumed regularly by humans.

Dna Barcoding Methodologies For The Identification Of Fish Species In Cooked Products, Rosalee S. Hellberg

Food Science Faculty Books and Book Chapters

Deoxyribonucleic acid (DNA) barcoding is a sequencing-based method that utilizes a standardized genetic region to identify species in combination with a reference database. DNA barcoding methodologies have been extensively applied to the identification of species in cooked seafood. While the typical genetic target associated with DNA barcoding is a ~650-bp region of the gene coding for cytochrome (cyt) c oxidase subunit I (COI), additional genetic targets include partial regions of the cyt b and 16S ribosomal ribonucleic acid (rRNA) genes. Most categories of cooked seafood can be identified using ~400- to 700-bp regions of these genes; however, canned seafood and …

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …

Development Of An Intact Mass Spectrometry Method For The Detection And Differentiation Of Major Bovine Milk Proteins, Emily F. Harley-Dowell

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

The authentication of products with claims regarding protein sources or compositions is a challenge for traditional analytical methods, which generally lack the required specificity whole protein analysis can provide. For example, the establishment of milk as “A2” is achieved through genetic testing of cows before milk production, with no methods to authenticate milk products themselves. Establishment of A2 milk is completed through genetic testing of the cows before milk production, but with no methods to authenticate the milk products themselves. Intact protein mass spectrometry (MS) has the potential to directly authenticate protein products, including specific proteoform claims. The development of …
