Walnut (Juglans regia) Phenols: I. Changes during ripening. II. Antagonisms for certain microorgainisms

Creator:: Diehl, John Harvey
Abstract:: Phenols from defatted walnuts were extracted with absolute methanol. The phenols were divided into four groups on the basis of molecular size. The antagonism of each group towards Escherichia coli, Staphylococcus aureus, and Aspergillus flavus was determined. Small polymers were the best antagonists of E_„ coli and Staph. aureus followed...

The reaction of (+)-catechin with N-Hydroxymethylacetamide : a model for cross-linking PVA resins with tannins

Creator:: Wallace, Kathryn Anne
Abstract:: Equal molar amounts of (+)-catechin and N-Hydroxymethylacetamide were reacted under acidic conditions. Thin-layer chromatography (TLC) was used to monitor the reaction. The reaction products were isolated by column chromatography using Sephadex LH-20 and elution with 95 percent ethanol. Three reaction products isolated included one disubstituted and two monosubstituted compounds. The...

Assessing the impact of temperature on grape phenolic metabolism

Creator:: Cohen, Seth D.
Abstract:: Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...

Development of a method to measure protein in red wines : a survey of protein, mannan and tannin in Pinot noir wines

Creator:: Smith, Mark R.
Abstract:: A number of methods to isolate and quantify protein in Pinot noir wines were evaluated. The combination of precipitation by acetone containing 10% w/v trichloroacetic acid followed by quantification with the Bradford assay, reported in yeast invertase equivalents yielded the most accurate results when compared to micro-Kjeldahl analysis. The technique...

Investigating the effects of temperature on secondary metabolism in Vitis vinifera L. cv. merlot berries

Creator:: Cohen, Seth D.
Abstract:: Grapes (e.g. Vitis vinifera L.) are one of the more important fruit crops from an economic standpoint with world market values over 550 million US dollars in 2007 and 2008, second to apples (United States Department of Agriculture). While a satisfactory level of ripeness is of primary concern, the quality...
