[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Shiga toxin-producing Escherichia coli (STEC) infections are clinically associated with hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS), ...
Development of active food packaging materials incorporated with nanocellulose and investigation of their toxicity
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nanocellulose is a renewable, lightweight, and biodegradable biomaterial that has potential applications in the food packaging industry. Nanocellulose ...
Antibacterial, plasmonic, and toxic properties of engineered nanoparticles
(University of Missouri--Columbia, 2016)
There has been increasing application of novel nanomaterials in recent years in the area of agriculture and food science. This dissertation aims to study novel nanomaterials and investigate their applications in food safety, ...
Valorization of purple corn pericarp using two-pot emerging thermal and non-thermal extraction technologies and evaluation of product quality, structure, and bioactivity
(University of Missouri--Columbia, 2023)
The pericarp of purple corn has traditionally been thought of as being a byproduct. However, it is an excellent source of high-value polyphenols (such as anthocyanins, proanthocyanins, etc.) that could be extracted and ...
Development of antimicrobial composite materials for food packaging applications
(University of Missouri--Columbia, 2022)
Due to increasing environmental concerns regarding plastic waste, the development of composite film materials from biodegradable polymers and natural food additives is gaining more attention. Over the last few decades, the ...
Puffing of okara/rice blends using a rice cake machine
(University of Missouri--Columbia, 2005)
Okara is the by-product of soymilk and tofu manufactures. It is cheap and nutritious having great potential to be applied in healthy snack foods. In this study, a puffed soy/rice cake product was developed and consumer ...
Prevention of biofilm formation on food contact surfaces by nanoscale plasma coating
(University of Missouri--Columbia, 2016)
Microbial biofilm formation can lead to a series of important safety problems in food industry because, once formed, the microbial cells are much harder to remove compared to plankton cells and can lead to circulating ...
Detection of viable Escherichia coli O157:H7 in food by propidium monoazide real-time polymerase chain reaction
(University of Missouri--Columbia, 2013)
Escherichia coli O157:H7 associated with food has caused many serious public health problems in recent years. However, only viable cells of this pathogen can cause infections, and false-positive detection caused by dead ...
Enhancing microbiological safety of water and food
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Human and animal feces are the main sources of pathogens associated with foodborne and waterborne disease outbreaks. The studies in Volume I proposed ...
Detection of viable escherichia coli in environmental water using a combined propidium monoazide staining-real-time PCR
