Extraction of Prebiotics from Jackfruit Seeds

Abstract

This research is to study extraction of prebiotics from Jackfruit seeds. Jackfruit seeds were preliminary

extracted using a lab-scale batch extractor to investigate effects of different solvents (distilled water. 50%

ethanol and 95% ethanol). particle sizes of ground jackfruit seeds (1.0-2.0, 2.0-2.8 and 2.8-5.6 mm). and solid

to solvent ratios (1 :2, 1:4, 1:6 and 1:8 w/v) by carried on the experiments at room temperature (30°C) for

60 minutes. The optimal conditions from the preliminary studies were using of 50% ethanol as a solvent,

a jackfruit seed at the particle size of 1.0-2.0 mm. and a solid-to-solvent ratio of 1:8, which gave about 6%

yield. These conditions were applied to pilot-scale batch extractor in addition to further study of extraction

temperatures (30 and 60°C) and extraction times (0, 30. 60. 90, 120. 150. 180. 360 and 480 minutes). After the

extraction time of 90 minutes. extraction equilibrium was reached. The extracted yield at temperature of 60°C

was only slightly higher than that extracted at room temperature. Therefore, the extraction at room temperature

was more economically suitable.
