Temperature and Light Effects on Ethyl Carbamate Formation in Wine During Storage

Abstract: MATERIALS & METHODSThe formation and/or increase of ethyl carbamate during storage of wine was monitored at 43°C 32°C and 22°C in the dark, at 22°C under fluorescent light and in a greenhouse with naturally fluctuating temperature and light conditions simulating commercial display of wines. The ethyl carbamate concentration of fifteen selected red and white table and dessert wines was determined initially, and after 3, 6, and 12 months storage. In most wines ethyl carbamate increased as a function of time and … Show more

“…Outro fator a ser considerado é a radiação luminosa 29,30 , que pode exercer uma influência na formação de carbamato de etila após a destilação, favorecendo a oxidação radicalar do cianeto a cianato e, assim, formando carbamato de etila (Eq. 4).…”

“…In a previous work, we reported the influence of light on the formation and storage of this contaminant in wine. Tegmo-Larsson and Spittler (33), researching the influence of light and storage on the formation of EC, evaluated the formation and/or increase in 15 samples of red and white table wines stored at three temperatures (43, 32 and 22°C) in the dark and at 22°C under fluorescent light. The concentration of EC was determined initially and after 3, 6 and 12 months of storage.…”

“…The ethanolysis of citrulline and urea to LAB strains able to derive energy from arginine catabolism may be more competitive in the stressful environment of wine form EC proceeds at elevated temperatures (Ough et al 1988) or at low to normal wine storage temperatures (Tegmo-(acid and alcohol) than those strains unable to do so. These strains may also excrete citrulline which can be used as a Larsson and Spittler 1990 ;Stevens and Ough 1993 ;Kodama et al 1994). The excretion of urea from arginine metabolism produced from arginine degradation may, in part, confer biological stability upon wine.…”

“…Spontaneous (natural) MLF in wine should be discouraged as the characconducted by Leuc. oenos strains (Tegmo-Larsson et al 1989 ;Tegmo-Larsson and Henick-Kling 1990a), while others claim teristics of indigenous LAB are not known. These strains may degrade arginine to produce citrulline that could promote the that MLF increases EC formation in wine Sponholz , 1992Ingargiola 1992).…”
