FIELD: chemical technology. SUBSTANCE: plant raw is washed preliminary with electroactivated solution of inorganic chloro-containing salt at pH 1.5-3.0 and redox-potential E1190-1000 mV. Then hydrolysis is carried out using electroactivated solution of the same salt at pH 1.5-2.0 and redox-potential E1190-1100 mV at increased temperature. Pectin solutions were concentrated and precipitated with ethanol. EFFECT: improved method of pectin preparing. 1 tbl
