Seafood processing is a sector of the seafood supply chain in which individuals and communities along Oregon’s coast rely on for food, livelihood, economic, and cultural relationships. Many coastal resilience studies focus on the seafood harvest (fishing) communities leaving the seafood processing sector relatively understudied. The objective of this thesis...
Nisin, an antimicrobial peptide used in food preservation was
evaluated for thermal stability. Nisin retained antimicrobial
activity after having been heated at 121°C for seven hours.
Anhydrous nisin and concentrated nisin solutions (5-10 mg/ml) were
still active after having been heated up to 190°C or 230°C. When
exposed to high...
Wine is known to have been enjoyed since ancient times. Although early civilizations where unaware of scientific mechanisms of the properties of wine, empirical methods allowed them knowledge of its intoxicating effects as well as its healthful properties. These properties lead the ancients to use wine for many purposes including...
A wildfire burned over 40,000 ha of conifer and mixed conifer-hardwood forest in
the Silver Creek drainage of southwestern Oregon in the fall of 1987 allowing me to
assess big game use of a large natural burn. I used fecal pellet group counts to estimate
habitat use and effects of...
As the global demand for seafood increases each year, there is a growing need to expand sustainable aquaculture in the interests of food security and resilience of coastal communities. Pacific oysters, Crassostrea gigas, are grown in West coast estuaries - where cultures often overlap with the federally protected native eelgrass,...
Cannabis sativa L. is emerging as an economically important crop, particularly for its high levels of cannabinoid production. One of these cannabinoids, cannabigerolic acid (CBGA), is the precursor to many well-researched cannabinoids such as the psychotropic delta-9-trans-tetrahydrocannabinolic acid (Δ9-THCA i.e., THCA) and the medically relevant cannabidiolic acid (CBDA). CBGA has...
Wetland restoration mitigates effects of agricultural development on water quality, flooding, and habitat loss. Multi-objective optimization for wetland locations and sizes has not included objective functions for water quality, hydrology, and habitat in unison, limiting analysis of trade-offs among these ecosystem services. This study establishes two methods to improve the...
The concept of terroir is commonly used as marketing tool to highlight unique characteristics of regional food products, however there is little scientific evidence of terroir pertaining to cheese. The purpose of this research was to investigate the potential impact of milk origin, pasteurization, and commingling on the sensorial, chemical,...
In an effort to develop an optical-acoustical understanding of ultrasound contrast agent microbubble dynamics in a micro-environment that resembles blood vessels, this thesis presents experimental work on optical trapping and acoustical probing of ultrasound contrast agent microbubbles confined in regenerated cellulose capillaries. First, we showed by acoustical means that the...
