Encapsulation protects iron from degradation or oxidation possibilities due to its\nencapsulation material. Glucomannan (GM) is a neutral polysaccharide consist of D-mannose\nand D-glucose connected with -1,4 linkage. Deactylation transforms solubility of glucomannan\nas well as its gel structure. These properties support for excipient application. The aim of this\nwork was to determine performance of deacetylated glucomannan as iron matrix. Deacetylation\nwas conducted heterogeneously. Deacetylation did not change the backbone of GM. Higher\nalkali concentration has better ability to encapsulate iron. Extended deacetylation time and alkali\nconcentration affect insignificantly on the performance of encapsulation to protect iron from\noxidation. The release of iron from the matrix influences by deacetylation degree.
