Abstract
Birch wood xylan, plasticized with glycerol and
reinforced with a nano clay, bentonite, was coated onto
paper as a barrier layer. Bentonite increased the
viscosity of plasticized xylan solutions, which had a
positive influence on coating ability. X-ray diffraction
traces of the xylan bentonite coatings confirmed that the
interlayer distance of the bentonite particles had
increased indicating that the xylan and/or glycerol
resides in the interlayer region. The water vapour
barrier properties were enhanced by dispersing bentonite
into the glycerol-plasticized xylan coating. The
improvement in properties varied from moderate to
significant (340 to 56 g m-2 d-1). The permeability of
diagnostic aroma compounds also decreased. Scanning
electron micrographs confirmed that the best
xylan-glycerol-clay coatings were intact without any
pinholes.
