Optimization of headspace temperature and time sampling for identification of palm sugar volatile components using response surface methodology

The aim of this work was to optimize equilibration temperature and time for analyzing volatiles components in palm sugar (Arenga pinnata) by headspace solid phase micro-extraction (HS-SPME) method. A 50/30 lm DVB/CAR/PDMS fiber was used to adsorb the volatile components from the headspace region. A...
