Abstract
Aloe vera is a plant that grows in Indonesia and its functional benefit has been
discovered .Aloe vera gel has been utilized in many functional food industries and
its skin becomes waste. Gel of aloe vera contains pectin. This research was aimed
to utilized both gel and skin of aloe vera to produce pectin. The effect of different
solvent (EDTA pH 8, SHMP pH 6, and HCl pH 3), temperature (60, 70, 80, 90oC)
and time (40, 60, 80 minutes) in pectin extraction towards the characteristics of
pectin powder (moisture content, ash content, yield, equivalent weight, methoxyl
content, galacturonic content, degree of esterification, and gel strength) were
studied. The result showed that solvents, temperature and time extraction qffected
pectin#scharacteristics. Pectin that extracted with SHMP pH 6 at 70oC and 60
minutes had the best characteristics. Aloe vera pectin had equivalent weight
882,02%, methoxyl content 4.20%, and galaturonoic content 43.80%. Aloe vera
pectin is Low Methoxyl Pectin with degree of esterification 45.63% and gel
strength 24.216 g.cm.
