Optimasi Pemurnian Asap Cair dengan Metoda Redistilasi

Abstract

furifcation of liquid smoke is vety important for the safety of the liquid smoke, because of content of tar and some carsinogenic substances. This research was done using redistillation process, with three factor treatment including : 1) distillation temperature, distillafon time and condensation temperature. The range of distillation temperature was ( 100 "C, 100-125"C, 125-150 9: and ) 150 "C. Distillation time was 30, 60 and 90 minutes, and condensation temperature was : 10-1 5"C, 15-25°C and 25-30°C. The results indicated no detected tar content in the purified liquid smoke, and optimum condition for redistillation process was : 122.5% for distillation temperature, distil/afion time was 69 minutes and condensation temperature was 24 "C. At this optimum condition the value of phenol, carbonyl and total acid were 2.24%, 5.60% and 15.7%, respective&.
