文摘

LLE allows a simple, cheap and reliable quantification of volatile phenols in wine. LOQ using GC–MS/SIM are well below the sensory threshold of these volatile phenols. Linear range is wide enough for direct application in most frequent contaminations. Activated carbon reduced significantly the concentration of volatile phenols. Isinglass, CMC and chitosan reduced headspace concentration of the volatile phenols.
