Pectin extraction from minced cocoa husks was carried out according to the method of Min et al. (2011) with some modifications. The minced cocoa husks was treated with 85% ethanol [substrate:ethanol, 1:4 (w/v)] for four times at 70 C for 20 min. The mixture was then filtered with a microcloth (60 lm) to obtain the residues. An extractant (water, citric acid at pH 2.5, citric acid at pH 4.0, hydrochloric acid at pH 2.5 or hydrochloric acid at pH 4.0) with a specific substrate–extractant ratio [1:25(w/v) or 1:10(w/v)] was added to the residues and incubated at a specific temperature (95or 50 C) and time (1.5 or 3.0 h). The slurry was then filtered with a microcloth. The filtrate was mixed with three volumes of 95% ethanol and centrifuged at 14,500g for 10 min. The precipitate obtained was washed with 70% ethanol and subsequently with 95% ethanol. The precipitate was then dried using a vacuum oven at 50 C.
