Pengaruh Waktu Penyimpanan Distilat Hasil Distilasi dari Sirup Fruktosa Terhadap Kadar Acetaldehydenya yang Diukur dengan Teknik Kromatografi Gas
ABSTRACT: Acetaldehyde is a
compound of aldehyde group that is very volatile and toxic. This compound can
be found in fructose syrups used in carbonate beverages. The syrups had been
distilled then analysed using gas chromatography. The concentration of
acetaldehyde was 289.78 g/g in the distillates kept for one week, 295.30 g/g
in those kept for two weeks, 429.45 g/g in those kept for three weeks, and
449.38 g/g in those kept for four weeks. The optimum column temperature was
programmed with initial temperature of 40 oC held on for four minutes, then
increasing by 40 oC/minute to 200 oC. It can be concluded that the longer the distillates
have been kept, the greater the concentration of acetaldehyde in the
distillates. A further research to investigate the present of microbe in the
distillates and the effect of pH should be conducted
