Development Of An Intact Mass Spectrometry Method For The Detection And Differentiation Of Major Bovine Milk Proteins, Emily F. Harley-Dowell
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 …
The Effects Of Sous Vide Cooking And Cysteine Proteases On Instrumental And Sensory Textural Properties Of Lower Value Cuts Of Beef, Ian Smith
All Theses
Sous vide cooking has the potential to increase the value of lower quality cuts of beef. Understanding the textural properties following a cook-chill sous vide process is crucial to maximizing this potential. The use of enzymes may further increase the value of these products if able to positively alter the texture of the final product.
The first research objective was to use instrumental texture analysis to evaluate potential relationships between enzymatic treatments and sous vide processing time of lower value cuts of beef. Three cuts were evaluated: infraspinatus (top blade), semitendinosus (eye of round), and beef tongue. Infraspinatus and semitendinosus …

Comparison Of Dna Extraction Methods For The Detection Of Canned Tuna Species With Dna Mini-Barcoding, Aubrey J. Emmi, Biola Fatusin, Rosalee S. Hellberg
Food Science Faculty Articles and Research
Tuna is susceptible to species mislabeling due to its high demand, quick rate of production, and wide range of price points. DNA barcoding, a sequencing-based technique, allows for the detection of species mislabeling by targeting a standardized region of DNA. A mitochondrial control region (CR) DNA barcode has been found to be capable of species discrimination for tuna, but it is challenging to recover the entire DNA fragment from canned tuna. While a short fragment of CR, referred to as a “mini-barcode,” has shown some success with canned tuna species identification, more research is needed to improve identification rates. The …
