Characterization of Liquid Smoke from Dried Water Hyacinth Using GCMS (Gas Chromatography-Mass Spectrophotometry) to Utilize Weeds as Food Preservative

Water hyacinth is a weed in Rawa Pening because of its rapid growth. A handling effort very crucial thing and must be done immediately. This study aims to characterize organic compounds liquid smoke from dried water hyacinth. ­­­­Characterization was carried out on which pyrolyzed at 200°C 600°C. Pyrolysis times were run 2 hours 6 hours. Liquid distilled before testing chemical composition using GCMS brand Shimadzu type QP 2010S. The results characterization are used decide that can utilized as food preservative. test report the produced had an acid percentage ranging 29.63% 37.23%, phenol 1.04 6.11%, remaining carbonyl 55.99% 68.90%. highest component value obtained 600°C pyrolysis conclusion preservative it contains acid, phenol, free Benzo (a) pyrene, cause cancer. So requirement for achieved, whereas generates acquisition natural preservatives utilize weeds. research helps us weeds resist environment manufacture preservatives.
