The aim of this work was to evaluate the influence of deacetylation
degrees (DD, 0-50-100%) and concentrations of glycerol (G, 0-5-10%) on the film
solution rheology and physical properties of salep glucomannan film. Solution
rheology experiments demonstrated that the deacetylation can be used as a tool
to regulate film solution flow, its spread and also coating applications.
Deacetylated salep films were produced with and without glycerol. The non-plasticized film was obtained with no
cracks and bubbles. The
deacetylation of purified glucomannan with the aid of glycerol significantly
changed the physical properties of the film by increasing its density, opacity
whereas light transmittance and moisture content were decreased due to the
formation of associations between acetyl free regions of the glucomannan
chains. Overall, 100% DD films with 10% glycerol demonstrated better physical
characteristics. Findings suggest that deacetylation is promising chemically
modification method for the production of food packaging materials.
