Abstract

In this paper, the optimum conditions for extraction of crude pectin from coffe pulp were investigated. The factors that were studied include: grain sizes coffee pulp, solvent/pulp ratio, extraction duration, temperature, pH extraction. The optimum condition has been found at: grain size-0.7x0.7 mm; solvent-H2SO4; solvent/pulp ratio-19/1; temperature-100oC; pH-1; extraction duration-1 hour. The amount of pectin in optimum conditions was 12.22%, the crude pectin/coffee pulp was 16.25%.
