Alginate is a kind of Kelp polysaccharide which can be degraded to oligomeric alginate.Oligomeric alginate was reacted with FeCl₃,and a series of Fe(Ⅲ)-oligoalginate complexes were obtained.When pH12,the complexes are stable in aqueous solution and reduced by Vitamin C and readily absorbed by human body.Meanwhile,the Fe(Ⅲ)-oligoalginate complexes prepared from oligomeric alginate with molecular mass of 21.4 kDa and 9.8 kDa contained 34% Fe.At 6~8 h after feeding the mouse with the complexes,the serum iron concentration of the mice rose obviously and the bioavailability of the complexes was 1.067.So they can be used as iron supplement.
- oligomeric alginate,
- Fe(Ⅲ)-oligoalginate,
