Effect Of Bentonite Additions Prior To Fermentation On Protein Stability In Edna Valley Sauvignon Blanc, Tymari Lore, Matthew Brain, Geraldine S. P. Ritchie

Food Science and Nutrition

Sauvignon blanc often requires large amounts of bentonite in order to remove haze proteins and make the wine heat stable. However, large bentonite additions can affect the sensory perception of the wine. We studied the effect of adding small amounts of bentonite before fermentation on the subsequent amount required after fermentation to heat stabilize the wine. Protein stability was evaluated in two lots of Sauvignon blanc juice from two blocks of the same Edna Valley vineyard. Bentonite (Volclay KWK, American Colloid Co.), 4.6 g suspended in 200 mL water, was added to 19 L of juice prior to fermentation. The …

Micronutrient Deficiencies As A Result Of Bariatric Surgery, Ashlie Lewis

Food Science and Nutrition

The most effective method of sustainable weight loss in obese patients is bariatric surgery. However, micronutrient deficiencies that can result after bariatric surgery can cause health problems that may outweigh its benefits. Micronutrient deficiencies are most common in patients who undergo Roux-en-Y gastric bypass or biliopancreatic diversion with or without duodenal switch. The majority of vitamin B12 and folate deficiencies studies showed significant prevalence rates in their patient populations. Most concluded that routine oral B12 supplementation was ineffective at resolving deficiency; very high oral doses (> 350 μg) or intramuscular injections of crystalline B12 were typically required. Studies of iron …

The Evolution Of Seeds, Ada Linkies, Kai Graeber, Charles A. Knight, Gerhard Leubner-Metzger

Biological Sciences

The evolution of the seed represents a remarkable life-history transition for photosynthetic organisms. Here, we review the recent literature and historical understanding of how and why seeds evolved. Answering the 'how' question involves a detailed understanding of the developmental morphology and anatomy of seeds, as well as the genetic programs that determine seed size. We complement this with a special emphasis on the evolution of dormancy, the characteristic of seeds that allows for long 'distance' time travel. Answering the 'why' question involves proposed hypotheses of how natural selection has operated to favor the seed life-history phenomenon. The recent flurry of …

Environmental Variables Influencing The Severity Of Pierce's Disease In California Grapevines, Christopher James Boisseranc

Master's Theses

This project was designed to correlate environmental variables with the development of Pierce’s Disease (PD), an infection caused by the gram negative bacterium Xylella fastidiosa (Xf), in grapes (Hopkins et al. 2002). PD is one of the most difficult crop pathogens to manage because it is vectored by insects and its continued presence in the vine is usually fatal. PD is influenced by the interaction of host, disease and vector, and probably many other environmental variables. The general objective was to study and identify the most important variables involved in the expression of Pierce’s Disease.
