N  aMoisture isotherms of cassava bagasse composites impregnated with cassava starch acetate solutions.h[electronic resource]  c2003  aThe industrial processing of cassava to obtain starch generates a great variety of residues, with bagasse being the main solid residue produced. The improper disposal of this material represents an environmental problem and could be avoided by using this residue as a raw material to obtain biodegradable products. The bagasse produced during the process to obtain starch from cassava was used to prepare composites for disposable trays. Samples of the composites were impregnated with cassava starch acetate at atmospheric pressure and under vacum condition. Moisture isotherms were determined and adjusted by GAB model. It was observed that the impregnation promoted an important decrease in sample higroscopicity, mainly at high relative humidities. These results suggest that starch acetate impregnation can be an alternative to water proofing biological materials like the composites obtained in this work.  abagasse  acassava  aimpregnation  aisotherms  astarch acetate1 aLAROTONDA, F.
