Risk management in particleboard production system design : a simulation study of the stochastic optimization problem

Creator:: Velazquez, Sergio Serrano
Abstract:: Effects of stochastic variations of parameters in the planning and design of a particleboard production system are studied. The solution obtained from a linear deterministic optimization model is compared against both the solution derived from the traditional stochastic programming techniques and the distribution of optimal objective function values obtained from...

Effect of Moderate Pressure Treatments on Microstructure, Texture, and Sensory Properties of Stirred-Curd Cheddar Shreds

Creator:: Serrano, J., Velazquez, G., Lopetcharat, K., Ramírez, J. A., and Torres, J. A.
Abstract:: A moderate high-pressure processing (HPP) treatment is proposed to accelerate the shredability of Cheddar cheese. High pressure processing (345 and 483 MPa for 3 and 7 min) applied to unripened (1 d old) stirredcurd Cheddar cheese yielded microstructure changes that differed with pressure level and processing time. Untreated and pressure-treated...

Effect of pressure-assisted thermal sterilization on conjugated linoleic acid (CLA) content in CLA-enriched milk

Creator:: Martinez-Monteagudo, Sergio I., Saldana, Marleny D. A., Torres, J. Antonio, and Kennelly, John J.
Abstract:: Conjugated linoleic acid (CLA) has been recently studied for its health-promoting and disease-preventing properties. The objective of this study was to evaluate the effect of pressure (100-600 MPa), temperature (60-120˚C) and treatment time (0-14 min) on CLA content in milk and anhydrous milk fat (AMF) rich in CLA. In milk...

Effect of high hydrostatic pressure and temperature on volatile off-flavors formation in milk

Creator:: Vazquez Landaverde, Pedro A.
Abstract:: The aroma of milk has been often defined as bland and pleasant, yet characteristic. Conventional thermal processing of milk can certainly extend shelf life, but inevitably changes its flavor. High pressure processing has been suggested as an alternative for milk pasteurization with improved fresh flavor retention. The objective of this...

Selection of Process Conditions by Risk Assessment for Apple Juice Pasteurization by UV-Heat Treatments at Moderate Temperatures

Creator:: Gayán, E., Torres, J. A., Álvarez, I., and Condón, S.
Abstract:: The effect of bactericidal UV-C treatments (254 nm) on E. coli O157:H7 suspended in apple juice increased synergistically with temperature up to a threshold value. The optimum UV-C treatment temperature was 55 °C yielding a 58.9% synergistic lethal effect. Under these treatment conditions, the UV-heat (UV-H[subscript 55 °C]) lethal variability...

What says your heart: community, learning, and education in a Nahua indigenous village

Creator:: Anderson, Jessica
Abstract:: The purpose of this thesis is to understand the experiences that Nahua children, in rural Mexico, have as they attend schools that are primarily influenced by formal Western education in relation to their own ways of learning and knowing. This research took place over the course of three months within...

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...

Multidisciplinary Approach to Evaluate the Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Soil Microbiota and Quality of Strawberries

Creator:: Nam, Jun Haeng
Abstract:: Oregon strawberries are known for their high quality, intense flavor, sweetness, and rich red color. With optimal weather conditions, including rainy and mild seasons, Oregon has one of the best strawberry farming environments. Amongst the factors for a suitable strawberry farming environment, soil significantly influences strawberry growth and quality. The...
