Optimization Of Fermentation Conditions For The Utilization Of Brewing Waste To Develop A Nutraceutical Rich Liquid Product, Shilpi Gupta, Amit Kumar Jaiswal, Nissreen Abu-Ghannam
Utilization of brewers’ spent grain (BSG), for the development of a fermented liquid product rich in value-added phenolic compounds was investigated. Changes in and liberation of phenolic compounds and antioxidant activity during fermentation of BSG was studied. The effect of various particle size (PS), solid liquid (SL) ratio, fermentation time and rotation speed was optimized using response surface methodology (RSM) for the purpose of improving bacterial growth and the enhancement in the release of polyphenolic compounds. Contour maps generated using the response surface equation showed that the experimental variables significantly affected the response. A production of 10.4 log cfu ...

Food Defense Among Meat Processing And Food Service Establishments In Kentucky, Morgan Webb-Yeates
Masters Theses & Specialist Projects
Agroterrorism is the deliberate introduction of a plant or animal disease with the
goal of causing fear, economic instability, illness, or death. After the 2002 terrorist
attacks on the World Trade Center, the security of the food supply is of increasing
concern to the United States. A major incidence of agroterrorism or food tampering would have far reaching impacts on the economy and public health. The first objective of this project was to determine knowledge and concern of agroterrorism in meat processing facilities in Kentucky, and to determine knowledge and concern of food tampering and food defense in food service ...
Isolation And Partial Characterization Of Bioactive Fucoxanthin From Himanthalia Elongata Brown Seaweed: A Tlc-Based Approach, Gaurav Rajauria, Nissreen Abu-Ghannam Dublin Institute of Technology
Isolation And Partial Characterization Of Bioactive Fucoxanthin From Himanthalia Elongata Brown Seaweed: A Tlc-Based Approach, Gaurav Rajauria, Nissreen Abu-Ghannam
Seaweeds are important sources of carotenoids, and numerous studies have shown the beneficial effects of these pigments on human health. In the present study, Himanthalia elongata brown seaweed was extracted with a mixture of low polarity solvents, and the crude extract was separated using analytical thin-layer chromatography (TLC).The separated compounds were tested for their potential antioxidant capacity and antimicrobial activity against Listeria monocytogenes bacteria using TLC bioautography approach. For bio-autography, the coloured band on TLC chromatogram was visualized after spraying with DPPH and triphenyltetrazolium chloride reagents which screen antioxidant and antimicrobial compounds, respectively, and only one active compound was ...

Antilisterial Characteristics Of Volatile Essential Oils, Leeann L. Slaughter
Theses and Dissertations--Animal and Food Sciences
This study explored the in vitro and in situ antilisterial inhibitory activity of 16 essential oils during indirect exposure: Spanish Basil oil (Ocimum basilicum), Bay oil (Pimenta racemosa), Italian Bergamot oil (Citrus bergamia), Roman Chamomile oil (Anthemis nobilis), Sir Lanka Cinnamon oil (Cinnamomum zeylanicum), Citral, Clove Bud oil (Syzygium aromaticum), Cumin Seed oil (cuminum cyminum), Eucalyptus oil (Eucalyptus globulus), Eugenol, Geranium extract (Pelargonium graveolens), Marjoram oil (Origanum majorana), Neroli extract (Citrus aurantium), Peppermint oil (Mentha piperita L.), Rosemary oil (Rosmarinus officinalis L.),and Spanish Sage oil (Salvia officinalis L.). All essential oils were tested against Listeria monocytogenes (ATCC 4644). In ...
Impact Of Rearing Conditions On The Microbiological Quality Of Retail Poultry Meat, Bridgshe Hardy University of Tennessee, Knoxville
Impact Of Rearing Conditions On The Microbiological Quality Of Retail Poultry Meat, Bridgshe Hardy
Poultry and poultry products are a leading source of foodborne pathogens and illnesses. The rearing conditions of poultry can be an influential factor on the presence of foodborne pathogens including Campylobacter and Salmonella because some types of rearing practices have increased risks in terms of biosecurity. However, there is a gap in knowledge of food safety in raw chicken products and no studies have reported the microbiological quality of turkeys produced under different rearing environments. Thus, the aim of this study was to compare conventionally and organically-reared whole chicken and turkey carcasses purchased from three retail outlets in Knoxville, TN ...
Isolation, Antibiotic Resistance, And Molecular Characterization Of Campylobacter From Poultry, Swine And Dairy Cows, Willie James Taylor University of Tennessee, Knoxville
Isolation, Antibiotic Resistance, And Molecular Characterization Of Campylobacter From Poultry, Swine And Dairy Cows, Willie James Taylor
This study was conducted to determine presence, antibiotic resistance, and genetic relatedness of Campylobacter on diverse farm types. Cloacal fecal samples from poultry (broilers, layers, and turkey breeders), and fecal rectal samples from non-poultry animals (farrowing sows, finisher pigs, and lactating dairy cows) were tested for Campylobacter using BAM protocols. Agar disk diffusion method was used to determine antibiotic resistance, and PFGE analysis to determine genetic relatedness of isolates recovered within the different farm types. Campylobacter was detected in 34.8% (range of 6.7 to 62.0%, P < 0.001) of cloacal samples from poultry, in 61.4% (range of 55.0 to 69.0%, P < 0.05), and 26.0% (range of 19.0 to 34.0%, P < 0.05) of rectal samples from pigs, and dairy cows, respectively. Antibiotic resistance was detected in 30.2% (range of ...
Evidence Of Transmission Of Escherichia Coli O157:H7 To The Tissues Or Phyllo-Plane Of Wheat, From Contaminated Soil, Seeds Or Water, Bismarck Antonio Martinez University of Nebraska - Lincoln
Evidence Of Transmission Of Escherichia Coli O157:H7 To The Tissues Or Phyllo-Plane Of Wheat, From Contaminated Soil, Seeds Or Water, Bismarck Antonio Martinez
Dissertations & Theses in Food Science and Technology
Escherichia coli O157:H7 is a human pathogen that can cause a wide spectrum of disease symptoms, such as bloody diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS). Escherichia coli O157:H7 illness are mainly associated with undercooked beef; however, in recent years outbreaks have been linked to fresh produce such as spinach, lettuce, and sprouts. In 2009, flour was implicated as a contamination source in the consumption of raw cookie dough resulting in 77 illness-cases. The objective of this research was to determine the possible route of transmission of E. coli O157:H7 into the phyllo-plane of wheat using ...

Analysis Of Microbial Diversity By Amplicon Pyrosequencing, Ryan Legge
Dissertations & Theses in Food Science and Technology
Microorganisms numerically dominate terrestrial biodiversity, and play important biochemical and geochemical roles in the environments they inhabit. To understand structure and function of complex ecosystems, it is essential to identify primary drivers of microbial diversity and community structure. Historically, the study of microbial ecology was reductive, limited to microbes able to be cultured and enumerated. Microbes meeting this criterion were thought to comprise the dominating members of the environments they were isolated from, however, estimates suggesting up to 99% of the endogenous species are uncultivable with existing methodologies; a concept that reflects experimental failure, rather than a verifiable conclusion. Therefore ...
