Abstract

The extraction of high-methoxyl pectin from the fruit peel of Citrus maxima was studied. The suitablecondition was the extraction at 80 °C without pH adjustment (pH was about 4.5) in 20 times by volume ofwater. For up-scale procedure, the peel was pre-soaked in water for overnight to wash out small molecularwater-soluble substances. Amberlite XAD-16 polystyrene was used to remove phenolic compounds beforeconcentration and precipitation of pectin. This suggested method was simple and inexpensive. The yieldof the obtained pectin was 7.23±0.19%. Its galacturonic acid content and degree of esterification were74.12±2.07% and 76.30 ±3.38%, respectively.
