The assurance of the quality a wine, both from point view tasting and food safety, its compliance with current regulations have led to development electrochemical sensors for analysis several analytes during last five years. On one hand, content glucose, alcohol, acetaldehyde, organic acids, phenolic compounds, sulphur dioxide, mercaptans, biogenic amines, preservatives some yeast can affect stability organoleptic properties. other them cause harmful effects on health consumer. So, early diagnosis is extremely important in wine samples. Enzymatic non-enzymatic sensors, which generally uses nanostructured materials or chemically modified electrodes enhance sensitivity selectivity, been reported this aim. ability these types be miniaturized their ease use make ideal candidates point-of-care devices.
