Abstract

The needs of excipients in pharmaceutical industry and raw materials in food industry such as starch, elevate the local plants to be utilized as an alternative source. Rambutan seed has the potentiality to be used as the one of the starch sources. The aim of the study was to produce starch and do the characterization included the heavy metal determination of starch obtained from rambutan seed. The starch was obtained by grinding the rambutan seed with water in ratio of 1:5. The characterization parameters were the organoleptic and microscopic features; yield value; moisture content; viscosity; and FT-IR spectra. The heavy metals measured were lead (Pb), copper (Cu) and zinc (Zn) by using Atomic Absorption Spectrophotometer instrument. The results showed that the rambutan seed starch had granular shape and gave 23.5% of yield value, 4.24 ± 0.78% of water content, 270.83 ± 7.22 cP of viscosity (in 5% solution), acceptable concentration of the existed heavy metal. It can be concluded that the rambutan seed can be suggested to be utilized as an alternative source for the industry to produce standardized starch.
