This paper deals with the extraction of pectin from tangerine orange rind by using acidic aqueous solution as extractant, precipitating with alcohol and analysing by Orthogonal Design. The best technological conditions are as follows: the acidity of extractant at pH2 the reaction time for 2 hrs, the concentration of alcohol for precipitating pectin at 50% by volume, and the final fine rate of pectin is 12.6%.
