| abstract |
The present invention describes methods of treating cellulosic materials with compositions comprising hemicellulose and/or lignin and sucrose fatty acid esters to alter the barrier function of such materials. The disclosed methods use hemicellulose or lignin in combination with sugar fatty acid esters to form films on cellulosic materials, including that the present disclosure provides products made by the methods. The materials thus treated have more effective barrier functions and mechanical properties, and can be used in any application that requires these characteristics. |
