This application note provides a method for the determination of iron content in wine using METTLER TOLEDO's EasyPlus UV/VIS spectrophotometer.
Why Is Iron Determination in Wine Important?
Wine is the most consumed alcoholic beverage in the world, obtained by the fermentation of grapes. Wine has a trace amount of metal present in it. The concentration of the metal component in wine depends on the type of grape, soil, environmental factors, and contamination during the manufacturing process. The presence of iron in wine can lead to cloudiness and precipitation. Hence, it is crucial to determine the concentration of iron in wine to maintain its quality.
How Is Iron in Wine Determined?
When reduced to Fe(II), iron forms a red-colored complex with 1,10-phenanthroline. The absorbance of this complex is measured at 510 nm using a METTLER TOLEDO EasyPlus UV/VIS spectrophotometer for the quantitative determination of iron in wine.
