To improve the physical and mechanical cardboard properties in technology the mod-ification of starch is frequently used. The work objective was to study the effect of biocata-lytic treatment of potato starch on the physical and mechanical cardboard properties based on recycled paper. The laboratory-made cardboard, consisting of 70 % hardwood hemicellu-lose and of 30 % MS-5B (GOST 10700-97) wastepaper, was used as the cellulose carrier. As the binder was used potato starch, pretreated with enzymes Pseudomonas amylodera-mosa isoamylase or Bacillus licheniformis pullulanase (Optimax L-1000). The square formed cardboard samples with a side length of 14 cm were impregnated with enzyme-pretreated starch paste, counting 200 units of enzyme activity per 1 g of dry matter for 3 hours at 50 °C and constant stirring. The impregnated cellulosic carriers were dried convec-tively on plates of organic glass at room temperature. The stretching test of materials was performed according to ISO 1924-2–85 in a laboratory test facility that included tensile test-ing machine TC 101-0,5b (Ivanovo) and the computer. The experiments demonstrated that pretreatment of starch with isoamylase enzyme led to a slight increasing in cardboard strength properties in comparison with cardboard, impregnated with non-fermented starch, whereas starch treatment with pullulanase enzyme, on the contrary, led to a reduction of almost all of the analyzed parameters.AuthorsO.S.
