Beschreibung
Zusammenfassung:	FIELD: natural substances. SUBSTANCE: invention relates to method for purification of pectin preparation. Method involves the complete dissolving squeezed out pectin coagulate, pectin precipitation, its washing out with ethyl alcohol and dissolving coagulate in ethylenediaminetetraacetic acid (EDTA) disodium salt an aqueous solution taken in preferable concentration 0.05 N. Method allows preparing pectin with high quality based on the enhancement of degree of its esterification. EFFECT: improved purification method, increased yield of ready product. 2 cl, 1 tbl, 3 ex
