ABSTRACT: The research study properties of the
starch-based foam from mixed between tapioca starch and octenyl succinate
starch (OSA starch), have addition alpha-chitin prepared by hot compression
molding method. Tapioca starch with 50% OSA starch was investigated. For composite foam tapioca starch mixed by adding
alpha-chitin at 5% - 30% of starch weight, it
was found that water absorption was reduced. The higher alpha-chitin content in blending foam, the denser of foam
structure observed which resulted in increasing of the foam density. The
maximum bending stress of composite starch was
decreased, but increasing the maximum bending strain.
