Survival Assessment, Inactivation Kinetics Models, and Farm-to-Table Quantitative Risk Analysis of Food Pathogens

Creator:: Deng, Kai
Abstract:: About 48 million cases of Foodborne illnesses (FBIs) are estimated to occur every year in the US. These are diseases caused by contamination of foods with bacteria, viruses, protozoa, parasites and toxic chemicals. Clostridium difficile infections (CDIs) are an important health-care and community associated problem. Since C. difficile spores have...

Development of antioxidant dietary fibers from wine grape pomace and their applications as functional food ingredients

Creator:: Tseng, Angela Y.
Abstract:: Wine grape pomace (WGP), the byproduct from winemaking, is a good source of polyphenols and dietary fibers, and may be utilized as antioxidant dietary fibers (ADF) for food applications. The objectives of this thesis research were to first determine the phenolic compounds, antioxidant and antimicrobial activities in red WGP under...

Development and characterization of shelf-life and sensory properties of restructured albacore tuna (Thunnus alalunga) rolls

Creator:: Roblero, Josef G.
Abstract:: Albacore tuna (Thunnus alalunga) rolls were developed using two albacore meat levels and three different treatment combinations. Albacore meat levels of 82 and 88% (Alb82 and Alb88) of the total weight formulation were examined. The different treatments consisted of 0.3% sodium tripolyphosphate (STPP), 0.3% STPP plus nitrites (150 ppm), and...

Investigation of film forming properties of beta-chitosan from jumbo squid pens (Dosidicus gigas) and improvement of water solubility of beta-chitosan, Investigation of film forming properties of β-chitosan from jumbo squid pens (Dosidicus gigas) and improvement of water solubility of β-chitosan

Creator:: Chen, Jeremy L.
Abstract:: The objectives of this project were to investigate the critical factors impacting the physicochemical and antibacterial properties of β-chitosan based films derived from jumbo squid (Dosidicus gigas) pens, and to evaluate the feasibility of improving water solubility of β-chitosan through Maillard reaction. The studies examined the effect of molecular weight...

Investigation of Optimal Extraction Conditions and Microencapsulation Technique for Stabilizing Anthocyanins and Polyphenols from Fruit Materials

Creator:: Wang, Wenjie
Abstract:: The objectives of this research were to investigate the optimal conditions for anthocyanins extraction from different anthocyanin rich fruit and to develop microencapsulation formulation for improving stability of anthocyanin extracts. In the extraction optimization study, two extraction methods, "conventional solvent extraction (CE)" and "ultrasound-assisted extraction (UE)" for three different anthocyanin-rich...

Rheological and spectroscopic characterization of surimi under various comminuting and heating conditions

Creator:: Poowakanjana, Samanan
Abstract:: Optimization of comminuting and heating conditions for surimi gel preparation obtained from three fish species: Alaska pollock (AP) (Theragra chalcogramma), Pacific whiting (PW) (Merluccius productus), and threadfin bream (TB) (Nemipterus spp.) was the focus of this study. Three parameters during comminution were separately evaluated: chopping time, chopping temperature, and salting...
Resource Type:: Dissertation
Full Text:: strongly recommended as it will allow the comminution process to be extended as long as possible until

Extraction and quantification of vitamins from raw, HTST, UHT, and PATP milk and of diatom-produced chitin and glucosamine

Creator:: Chotyakul, Nattaporn
Abstract:: Analytical chemistry is an essential qualitative and quantitative tool to describe foods and biomaterials and their changes during production, processing and distribution. In this work, rapid analytical procedures for the extraction and quantification of components in fluid milk and diatom fermentation broth were developed. Analytical methods to measure the concentration...

The Incorporation of Novel Water-Soluble Potato Protein Extract in Pacific whiting (Merluccius productus) Fillets Through Brine Injection Technology to Improve Quality

Creator:: Pasewark, George D.
Abstract:: Pacific whiting (Merluccius productus) is one of the most abundant fisheries on the American west coast. However, these fish are historically underutilized due to quality issues resulting from fillet softening that occurs as a result of both endogenous and exogenous (Myxosporidian parasite infection) cathepsin protease action during either storage (cathepsin...

Genomic mapping of efflux pumps in Listeria monocytogenes and their contribution to cadmium and fluoroquinolone tolerance

Creator:: Domen, Andrea
Abstract:: Listeria monocytogenes is the third most deadly foodborne pathogen in the United States. The young and elderly, as well as pregnant and immunocompromised people are the population most susceptible to serious illness and death from listeriosis infections. Unlike most foodborne pathogens, L. monocytogenes does not live a solely enteric lifestyle....
