Abstract
Polysaccharides from solid wastes of the processing tomato industry (Lycopersicon esculentum Hybrid Rome) were extracted using a simple and rapid method, purified and chemically characterised.
The yield of biopolymers represented 7.5 % of lyophilised biomass.
The polysaccharide showed a complex structure.
On the basis of NMR data, the repeating unit was constituted by eight monosaccharides, three of them with an
manno configuration, four residues with an gluco-galacto configuration and one residue showing a 
gluco-galacto configuration.
The specific viscosity (
) of the biopolymer, performed at different values of concentration and pH, showed a dependence with respect to the concentration, and the maximum value of viscosity was obtained at pH 3.0.
