EXTRACTION OF PECTIN FROM Mesona chinensis BENTH

Abstract

In this study, the extraction conditions of pectin from Mesona chinensis Benth were
examined. The highest yield of pectin was 20.67% in the extraction condition of citric acid 12% at 85 ºC in 90 minutes. The results of analysis and characterization of pectin showed that the pectin equivalent weight (7042.25), methoxyl content (3.162%), anhydrouronic acid (42.944%) and the degree of esterification (41.083%). Based on the value of methoxyl content and the degree of esterification, pectin from Mesona chinensis Benth can be categorized as low-methoxyl pectin.
