The physicochemical properties of pectin depend mainly on the plant source and conditions selected for isolation and purifi-cation of pectin. Extraction is therefore an important step in the isolation and recovery of pectin . Mineral acids such as hydrochloric acid and nitric acid
had been employed to extract pectin from cocoa husks. However, using mineral acids in pectin production generate effluents which lead to environmental problems and economical inconveniences. In addition, water and citric acid had been employed to extract pectin from cocoa husks. Particularly, information on the effect of processing methods on the yield and quality of pectin from cocoa husks (Malaysia) using various extractants is not available. The objective of the present study was to investigate the effect of extraction conditions
including temperature, time and substrate–extractant ratio on the yields, uronic acid contents, degrees of methylation and degrees of acetylation of pectins obtained from cocoa husks
using different extractants and pHs.
