OPTIMASI PEMURNIAN ASAP CAIR DENGAN METODA REDISTILASI [Optimation of Liquid Smoke Purification by Redistilation Method]

Abstract

Purification of liquid smoke is very important for the safety of the liquid smoke, because of content of tar and some carsinogenic substances. This research was done using re-distillation process, with three factor treatment including : 1) distillation temperature, distillation time and condensation temperature. The range of distillation temperature was ‹ 100°C, 100-125°C, 125-150°C and ›150°C. Distillation time was 30, 60 and 90 minutes, and condensation temperature was : 10-15°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°C for distillation temperature, distillation 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%, respectively.
