Abstract

Effect of concentration of sodium bisulfite to vitamin C content, total
sulfite residue and consumer hedonic level of rambutan syrup has been studied. Research method was experiment by complete random design. Vitamin C content was analyzed by the iodium titration, the total sulfite  residue by  distillation analysis  (Rangana, 1977),  and consumer hedonic  level  by  hedonic scale  test  with  80  untrained panelists. Analysis data was done by analysis variance at 5% level of significance and continued with the Tukey test. Based on research result showed that concentration of sodium bisulfite have a significant effect to   vitamin C content and total sulfite residue of rambutan syrup. Vitamin C content and total sulfite residue increased with the increasing concentration of sodium bisulfite. Concentration of sodium bisulfite has a significant effect to aroma of rambutan syrup, otherwise no influence at color andflavor.
