Industrially isolated pea starch was physically processed using: gelatinization, autoclaving and cooling cycles, and dehydration by spray-drying. The experimental pea starch preparation, with crystallographic pattern of the B-type had 30% d.m. of resistant starch as the RS₂/RS₃-type and showed a hydrophilic-hydrophobic character. During in vitro studies the sorption of some biologically active components was recognised. Specially, the sorption of deoxycholic or taurocholic acids and ions of toxic metals as lead and cadmium was noteworthy. Also, the sorption of cholesterol was observed. Physically modified pea starch preparation is suggested as additive to ‘functional foods’ and as agent preventing the colon diseases.
