Allgemeine Beschreibung

4-Ethylguaiacol wurde als einer der wichtigsten Aromastoffe in grünem Tee, Rotwein und Sojasauce identifiziert.

Anwendung


  • Co-culture fermentation by Saccharomycopsis fibuligera and lactic acid bacteria improves bioactivity and aroma profile of wheat bran and the bran-containing Chinese steamed bread.: This study examines the impact of co-culture fermentation on the bioactivity and aroma of wheat bran, with a focus on the contribution of 4-Ethylguaiacol to flavor enhancement in food processing, emphasizing its potential for improving the nutritional and sensory quality of baked goods (Tang et al., 2024).

Wood creosote, a mixture of phenolic compounds, suppresses in vitro contractions of rat intestine. To identify a compound in wood creosote able to inhibit intestinal motility, we screened its constituent phenolic compounds and found 4-ethylguaiacol (4-EG) as an active compound.

Immobilization of salt-tolerant yeasts considerably decreases the total time required for the flavour development in soy-sauce processes. For immobilization of cells, alginate gel is mostly used as support material. However, alginate is not very suitable for use in soy-sauce processes

Contamination of wine by Dekkera/Brettanomyces bruxellensis is mostly due to the production of off-flavours identified as vinyl- and especially ethyl-phenols, but these yeasts can also produce several other spoiling metabolites, such as acetic acid and biogenic amines. Little information is

Analyses of commercially available wines suggested non-Brettanomyces sources of 4-ethylphenol and 4-ethylguaiacol. Grapes, enological additions, exposure to plastics, and oak-barrel aging were potential inputs considered. Investigations of whole grape bunch samples from two major red wine Vitis vinifera cultivars (L.

Volatile phenols produced by Brettanomyces dekkera have been associate with off-flavors of wines. A versatile liquid chromatography-tandem mass spectrometry together with an HPLC-DAD-fluorescence methods were developed for the quantitation of two phenols, 4-ethylphenol (4EP) and 4-ethylguaiacol (4EG), in red and
