Abstract:
Objective The adsorption effects of four sorts of dietary fibres from seaweeds on exogenous NO~-_(2) were studied in vitro and in vivo.Methods By simulating the environment of stomach and small intestine in vitro,and feeding rat in vivo.At the same time,the adsorption effect of wheat bran was studied comparatively.Results The results showed that:(1) the adsorption effect of dietary fibres on NO~-_(2) were related with the pH and the species of dietary fibres.Under the simulated stomach environment,the adsorption capacity of Laminaria japonica was the strongest with 1.19 mg?g~(-1),the next was Eucheuma with 0.94 mg?g~(-1),and Sargassum was the weakest with 0.60 mg?g~(-1).The adsorption ratio of Laminaria japonica and Eucheuma was significantly higher than that of wheat bran(P
