Flavor control in dairy products and beer with special reference to diacetyl

Creator:: Pack, Moo Young
Abstract:: The stability of diacetyl in fermented milk and the removal of diacetyl from beer were studied. A convenient method for the determination of diacetyl in beer, established by Owades and Jakovac, was modified and applied for flavor analyses of dairy products. Through this method, diacetyl in 12 samples could be...

Assessing Mercury Levels, Health Metrics, and Immune Function in Non-stranded Male California and Steller Sea Lions in Oregon

Creator:: Rae, Samantha N.
Abstract:: California and Steller sea lions (Zalophus californianus, Eumetopias jubatus, respectively) are considered sentinel species because they have long life spans, are long-term coastal residents, feed at high trophic levels, and have large blubber stores that serve as depots for anthropogenic toxicants. There are few studies on sea lion health and...
