Oxide modified Konjac glucomannan(KGM)were compound with potato starch for the preparation of new plants capsules. An orthogonal test was conducted to investigate the effects of the ratio of oxidation konjac glucomannan(OKGM)/potato starch,glue concentration,reaction temperature and reaction time on the preparation of OKGM-potato starch composite film. The results showed that it would be the optimal parameters of the composite film when the OKGM/potato starch ratio was 1∶3,glue concentration was 1.25%,reaction temperature was 60℃,and reaction time was 3 h. Under this condition,the tensile strength of the composite film was 20.8 MPa,the break elongation was 21.3%,the light transmittance was 21.9%,the coefficient of moisture permeability was 5.1×10-9 g/(mm·h·mmHg),the coefficient of moisture absorption was 7.6%,the droplets permeation time was 33 min/mm,and these performances are all satisfied the requirements of hollow capsules,so they can be used in the preparation of plant capsules.
