Abstract

Physico-chemical properties  and enti-becterial agent of liquid smoke palm shell  for food preservation has been performed.  The liquid smoke  was made by dry distillation method, and then partially purified by precipitation­ filtration and distillation. Chemical components were assayed using GC-MS and  anti  bacteria.  capacity  was  assayed  using agar  diffusion  method. Results showed that differences in purification treatment leads to a different physico-chemical  properties  and  anti bacterial  capacity of liquid  smoke produced.  Partially purified  of pure  liquid smoke produced  followed by distillation process have characteristic of clear, impurities of 0.09% and pH of 3.07 .Dominant chemical compounds found in the various treatments were cyclopentanone, 2-furancarboxaldehyde. acetic acid. and acid propanoate.  Partial purified liquid smoke by precipitation-filtration showed inhibition on bacterial growth of E. Coli and S. aureus. but could not inhibit the  growth  of  Salmonella,  whereas partial  purified  of  liquid  smoke  by distillation did not have inhibitory effect on the growth of E. Coli, S aureus and Salmonella.
