Color of Seyval blanc Juice and Wine as Affected by Juice Fining and Bentonite Fining During Fermentation
Abtracts. Two experiments were conducted to examine the effects of fining agents applied prior to and/or during fermentation on the color of Seyval blanc wine. In experiment one, kieselsol (Ke) at 719 mg/L; polyvinylpolypyrrolidone (PVPP) at 719 mg/L; bentonite (Bn) at 960 mg/L; combinations of these levels of Ke, PVPP, and Bn; sulfur dioxide (SO2) at 100 mg/L; and a control were applied to the...
متن کاملMethoxypyrazines in Sauvignon Blanc Wines, Detection of Addition of Artificial Aroma
Rajchl A., Čížková H., Voldřich M., Lukešová D., Panovská Z. (2009): Methoxypyrazines in Sauvignon blanc wines, detection of addition of artificial aroma. Czech J. Food Sci., 27: 256–266. Methoxypyrazines are the principal aroma components responsible for the vegetative and herbaceous green bell-pepper flavour of Sauvignon blanc wines produced in Moravia. The aroma profiles of 8 samples of Mora...
متن کاملHeat-Unstable Proteins in Wine. I. Characterization and Removal by Bentonite Fining and Heat Treatment
The effect of bentonite fining on the total proteins and the heat-unstable (80°C, 6 h; 4°C, 12 h) proteins in GewLirztraminer, White Riesling, Sauvignon blanc, and Sylvaner wines was investigated. Protein molecular weights (MW), isoelectric points (pl), and glycoproteins were determined by using lithium dodecyl sulfate polyacrylamide gel electrophoresis (LDS PAGE) and two-dimensional isoelectri...
متن کاملHeadspace solid-phase microextraction-gas chromatography-mass spectrometry for profiling free volatile compounds in Cabernet Sauvignon grapes and wines.
The complex aroma of wine is derived from many sources, with grape-derived components being responsible for the varietal character. The ability to monitor grape aroma compounds would allow for better understanding of how vineyard practices and winemaking processes influence the final volatile composition of the wine. Here, we describe a procedure using GC-MS combined with headspace solid-phase ...
متن کاملChanges in the Phenolic Composition and Antioxidant Activity of Pinotage, Cabernet Sauvignon, Chardonnay and Chenin blanc Wines During Bottle Ageing
The effect of bottle ageing on the antioxidant activity of Pinotage, Cabernet Sauvignon, Chardonnay and Chenin blanc wines, using the 2,2'-azino-di-(3-ethylbenzothialozine-suIphonic acid) radical cation (ABTS*) and 2,2-diphenyl-l-picrylhydrazyl radical (DPPH') scavenging assays, was determined. Storage at 0°C, 15°C or 30°C for a period of 12 months resulted in a significant (p < 0.05) decrease ...
