Abstract: It was discussed the influence of temperature, acidity and time of extraction on yield of pectin extracted from shaddock skins. Optium conditions were: at 90－95℃, added 0. 395% in weight of hydrogen chloride and abstracted for 45min. Optium decolored conditions were: at 15℃, added 5－7% in volume of hydrogen peroxide(30wt. %), placed for 1-2days.

Key words: Shaddock skins Pectin Decoloration
