ADSORPTION OF HETEROCYCLIC AMINES BY INSO LUBLE DIETARY FIBER

Adsorption of IQ, Trp-P-1 and Trp-P-2 on insoluble dietary fiber, cell ulose, CM-cellulose, xylan, chitin, collagen and acid detergent fiber (ADF: containing cellulose and lignin) from nine species of edible pla nts was measured by HPLC. Cellulose and ADF from burdock, dropwort and bamboo shoot showed high adsorptive power for IQ, Trp-P-1 and Trp-P-2 . The results suggest that consumption of edible plants containing cel lulose would help to prevent the internal absorption of heterocyclic a mines formed in cooked fish and meats.
