Effect of the red and green linearly polarized light upon polysaccharide depolimerization-repolymerization

in starch granules (in English)

Polimery 2007, No 11/12, 874


Summary

Aqueous suspensions of normal corn, waxy corn and potato starches were illuminated for 5-50 h with linearly polarized light (LPL) of 480-560nm (green) and 600-680nm (red). Similarly as with white LPL, depolymerization followed by repolymerization of starch polysaccharides, that is amylose and amylopectin, resulted from such illumination. Quantitative effects caused by illumination with the green and red LPL depended on the botanical origin of starch but qualitative effects were similar to those observed on illumination of those starches with white LPL.


Key words: linear polarized light, colour light, starch, botanical origin, depolymerization, repolymerization
