FIELD: chemistry.
SUBSTANCE: method involves treating the feedstock with an aqueous formalin solution, holding in hydrochloric acid acidified water, extracting with an aqueous solution of ammonium oxalate, filtering and concentrating the extract on an ultrafiltration column with simultaneous dialysis, lyophilic drying of the desired product. Vegetable feedstock is pre-soaked in water at room temperature for 20-24 hours. Holding in hydrochloric acid acidified water is carried out at the pH of 0.8-3.5 and the temperature of 45-52°C for 3-4 hours. And as a feedstock, dried upground part of Sosnovsky hogweed or Siberian hogweed is used.
EFFECT: invention allows to obtain pectin with an increased yield of the desired product.
