Effects of glycerol incorporation on Semi-Refined Carrageenan film properties
Bakti Berlyanto Sedayu
Victoria University, Australia
Derived from renewable, abundant seaweed, carrageenan-based films are
becoming popular as food packaging material. In this work, semi-refined
carrageenan (SRC) plasticized with glycerol were developed and characterised.
The mechanical strength, moisture content, and optical properties of the
films generally increased significantly with increasing glycerol concentration,
however, the water vapor permeability decreased. In particular, the tensile
strength and elongation at break increased at plasticizer additions of up to
40% and 50% (w/w) respectively. The addition of glycerol also improved
the thermal stability and surface morphology of the films. The results show
that the properties of the SRC films were comparable with refined carrageenan films suggesting that SRC has potential to be
furthered developed into less expensive food packaging materials.
