An attempt was made to prepare the Citrus peel's pectin in the process of manufacturing orange juice from Natsudaidai peel by using the Ion exchange resin.1) For the extraction of pectin from Citrus peel, dilute hydrochloric acid (0.1%) was used.2) Extracted pectin was precipitated by the addition of CuCl_2 solution (0.02%) and filtered by the cloth.2) This pectin-Cu salt (1000g) was dissolved by the addition of hydrochloric acid (4cc.). This pectin-Cu-HCl solution was very viscous solution.4) This viscous pectin-Cu-HCl solution was filtered by the Ion exchange resin (Cation- and Anion-).5) The prepared pection solution was free from Cu, colorless, and had neither bitter nor sourish taste. Its jelly strength was 5〜6.6) Dry pectin prepared from this pectin solution had a very high jelly strength (over the grade 110), and its properties were superior to the Citrus pectin products in the market, which were manufactured by other methods.
