Structure and Adhesive Properties of Oxidized Cassawa Starch
Abstract:
Effects of catalyst FeSO4 on molecular mass distribution,contents of carboxyl and carbonyl groups,and adhesive properties of the oxidized starches were investigated.The results show that the catalyst reduced the oxidation time of cassawa starch to 0.5 h,and increased the carboxyl and carbonyl contents in the oxidized starches by more than 105% and 12%,respectively.Gel Permeation Chromatography analysis showed that the molecular mass of the oxidized starch prepared with the catalyst was smaller,and the molecular mass distribution was more uniform than that of the starches oxidized without a catalyst.The solid content of the adhesive prepared by catalytically oxidized starch was as high as 28.9%.The adhesive strength of the adhesive was 57 N after drying for 15 min.
