Abstract
Pectin is extracted from citrus fruits or fruit peel by a process in which the parent material is treated with a restricted quantity of a softening or swelling agent prior to, or simultaneously with, its extraction with a neutral or acidified aqueous solvent. The softening agents used are alkyl or aryl esters of aliphatic or aromatic acids, such as ethyl or butyl acetate, methyl or ethyl benzoate or salicylate; xylene; halogen substituted hydrocarbons such as chloroform; or inorganic sulphocyanides such as calcium sulphocyanide; or mixtures of these. The softening agents are added in quantity not exceeding one-fifth that of the material treated and remain present during the extraction. The extraction is preferably carried out at about pH2 and when mineral acids such as sulphuric or hydrochloric are used it is preferred to add a buffer consisting of a weak acid or a salt thereof, such as tartaric or citric acids, sodium phosphate, or potassium tartrate. The Provisional Specification contains an example according to which a much larger proportion of butyl acetate is employed.
