Isolation and characterization of pectin from peel of Citrus tankan.
A pectin was extracted from the peel of Citrus tankan with a yield of 2.75%. The uronic acid content was 80.0%, and the degree of methoxylation was 63.2%. The pectin was composed of D-GalA, D-Gal, L-Ara and L-Rha in the molar ratio of 100:11.3:3.6:2.6. The molecular weight was estimated to be approximately 9.2 x 10(4). The pectin formed a gel by conventional procedures.
