Low-moisture food (LMF) processing environments pose a persistent food safety risk due to Salmonella survival and harborage on surfaces. This work investigates persistent bacterial populations (PBPs) in LMF production environments, focusing on identifying a suitable surrogate and evaluating sanitation strategies. Three potential surrogates, Escherichia coli MP 26, Enterococcus faecium, and Pediococcus acidilactici, were compared to Salmonella PBPs formed in nonfat dry milk (NFDM) on stainless steel coupons stored at 25°C under 30% or 70% relative humidity (RH) using two different inoculation methods. E. faecium showed survival patterns most similar to Salmonella, with no significant differences in log reductions (p > 0.05), …

Food science provides an opportunity to engage high school students in Science, Technology, Engineering, and Mathematics (STEM) by connecting classroom concepts to real-world applications. Despite the field’s relevance to public health, food safety, sustainability, and innovation, food science remains largely absent from high school curricula, and few students recognize it as a viable STEM pathway. This research addressed this gap by evaluating immersive summer camp experiences and teacher-focused curriculum review as strategies to increase food science awareness and interest among students and educators. A literature review traced the historical development and current landscape of K–12 food science education, identifying barriers …

Cardiovascular diseases are one of the leading causes of mortality worldwide in which hypertension is a risk factor. Present pharmacological interventions require long-term adherence to the therapy and are often associated with undesirable side effects. Moreover, treatments have overlooked the role of the microbiome in the development of hypertension. Egg white hydrolysate (EWH) has exhibited antihypertensive properties with potential to be used as a natural alternative for the prevention and management of hypertension. However, EWH peptide’s effect on the gut microbiome remains yet to be elucidated. Studies have described that a portion of the ingested protein can remain undigested as …

This article presents the development of a 3D food printing (3DFOODP) system incorporating a core-shell structure to encapsulate a model compound, methylene blue (MB). A coaxial nozzle configuration was employed to fabricate 3D-printed samples, featuring a starch core and a pH-responsive alginate-pectin (Al-P) shell. The optimal 3D printing conditions were determined as 11 wt% starch as the core along with 2 wt% Al-P with 0.02 M CaCl2 as the shell at printing temperatures of 95 degrees C and ambient temperature (23 degrees C), respectively. The overall 3D printability at this condition was 98 %, closely matching the digital 3D design. …

Dissertations and Theses (Open Access)
Prion diseases are fatal neurodegenerative disorders caused by the misfolding of the normal prion protein (PrPC) into its infectious form (PrPSc). While the zoonotic potential of chronic wasting disease (CWD) remains uncertain, the presence of prions in food products raises public health concerns. Additionally, therapeutic strategies for prion diseases remain limited. This thesis presents a methodological exploration of the Protein Misfolding Cyclic Amplification (PMCA) technique to address these challenges in two key areas: (1) detecting CWD prions in processed meats subjected to common cooking procedures, and (2) identifying potential anti-prion compounds through a high-throughput PMCA adaptation. …

This study aims to investigate detergent sodium deoxycholate (SDC) and sodium dodecyl sulphate (SDS) treatments, with a focus on each detergent's ability to enhance the extraction of immune-related proteins from camel milk fat globular membrane. Milk was separated into cream and skimmed milk. The cream was then treated using 0.4 % SDS, 2 % SDC, 6 % SDC or 10 % SDC. Extracted proteins were trypsin digested and analysed using liquid chromatography-tandem mass spectrometry. Higher SDC concentrations (6 % and 10 %) resulted in marginal improvements in protein identification (44 unique protein groups). Protein abundance distributions showed minimal differences across …
