The aim of this work is the utilization of sugar industry waste: sugar beet pulp and
molasses, as a new approach for manufacture of raw chemicals that can be further
converted into valuable products for food packaging industry. Dextransucrase is one of the
main enzymes which catalyze the transfer of D-glucopyranosyl residues from sucrose to
biopolymer dextran. New approach proposed the use of sugar beet pulp as a supporter for
cells immobilization and molasses as the source of nutrient for production of
dextransucrase by natural isolate from water kefir grain. Afterwards, the dextransucrase
was purified and incubated in 5% sucrose/sodium acetate buffer solution (pH 5.4) at 30◦C
for 48 h, in order to produce dextran. Dextran obtained by this procedure was used for
preparation of edible biobased coating to prolong shelf-life of tomato. In order to improve
mechanical properties of these coatings, poly(glycerol) was added. The dextran coatings
were characterized by mechanical an...d thermal properties. Moreover, the tomato was
coated with dextran film and evaluated periodically for various quality parameters. The
tensile strength and elongation at break of dextran coatings was 1.62 MPa and 230%,
respectively. Dextran coatings showed adequate thermal stability and could be safely used
for applications up to 200oC. The coated-tomato reduced texture softening, weight loss
and acid production compared with the uncoated tomato, which implied the prolongation
of tomato shelf-life.
