[Food hygienic indexes on biodegradable polymers].
Current specifications for food packaging made of polyolefine plastics were applied to biodegradable plastics. No lead and cadmium were detected in any biodegradable plastic samples with the exception of bacterial cellulose, which contained trace amounts of lead and cadmium. Potassium permanganate consumption amount was less than the current specification level for polyofines. Sugars leached from bacterial cellulose was 22 +/- 1 microgram per 100 cm2 as glucose, and amino acids leached from poly-gamma-methylglutamate films was 8 +/- 3 micrograms per 100 cm2 as glutamic acid.
