Recently, concerns about the volatile hazardouscompounds including acetaldehyde, methanol, and fusel oils inalcoholic beverages, which cause hangover such as headache anddizziness after consumption, have been raised. The volatilehazardous compounds might also lead to an increased incidenceof liver diseases and even cancers with a high consumption ofalcoholic beverages, Acetaldehyde is a volatile compound naturallyfound in alcoholic beverages and used as flavor in many foods.However this is also regarded as possibly being carcinogenic tohumans. Furthermore, acetaldehyde with alcoholic consumption isrecently classified as Group 1, carcinogenic to humans. On theother hand, methanol is generated from demethoxylation of pectinby pectinolytic enzyme during alcoholic fermentation. Higheralcohols occur naturally in alcoholic beverages as by-products ofalcoholic fermentation and are generally regarded as importantflavor compounds. In the current study, we reviewed on the healthconcern, maximum levels, analytical methods, and current levelsof hazardous volatile compounds in alcoholic beverages.
