The hot acid extract was filtered through a Whatman No. 1 filter paper. The filtrate was coagulated using an equal volume of 95% ethanol and left for 2 h to allow the pectin to float on the surface. The gelatinous pectin flocculants were then skimmed off. The extracted pectin was then filtered and washed 2 - 3 times with ethylalcohol to remove any remaining impurities. Finally, the precipitate was dried at 35 - 40°C in hot air oven and percentage yield was calculated.
