Abstract


Xilitol poliester was produced by esterification involving xilitol and fatty acid metil ester (FAME) from DALMS (destilate fatty acid from palm oil). The reaction was affected by : reaction time, temperature and reactant molar ratio. Optimum condition based on response surface methodology (RSM) analysis was as follows : reaction time 6,78 h, reaction temperature 144,5ºC, substrate molar ratio 10, 3:1 and convertion of xilitol poliester 86,4%. Xilitol poliester produced was composed of short chain fatty acid. The physical properties of xilitol poliester (smoke point, melting point, refractive index, spesific gravity and viscosity) were little bit lower than those of palm oil. Analysis of hydrophilic lipophilic balance showed that xilitol poliester may be used as emulsifier. Hydrolitie activity of pancreatic lipase to xilitol poliester lower than that of palm oil. Perokside value of xilitol poliester was lower than that of palm oil.
