Research on the Processing Methods of Plasticizer in Baijiu(Liquor)

A simple, rapid and safe processing method of plasticizer in liquor had been developed by using the physical absorption of active carbon on the premise of guaranteeing liquor taste and liquor flavor. Meanwhile, the experience formula for the addition level of active carbon was determined. Besides, various factors including the materials, structure, and use level of carbon, and the acidity, temperature and solvent effects of the system, and the stirring and settling time etc., which influenced carbon absorption, were investigated. The results showed that, as temperature was less than 50 ℃, alcoholicity was less than or equal to 52 %vol, stirring time was between 10 to 15 minutes, and settling time was above 2hours, the use of coconut shell active carbon could effectively remove plasticizer in liquor with its use level determined by the experience formula.
