Incorporação de urucum como aditivo antioxidante em embalagens biodegradáveis a base de quitosana

Abstract

The objective was to develop and characterize a biodegradable packaging using chitosan as polymeric matrix, plasticized with glycerol, as well as evaluate the effect of adding a natural antioxidant additives (annatto) in antioxidant protection in packaging. The cans were prepared by casting containing 1.5% of chitosan, 0.15% glycerol and 0.25 to 1.0% of coloring. Palm oil packed with the fi lms containing the additive was monitored at 0, 7, 15, 30 and 45 days of storage under accelerated oxidation conditions (63% UR/30ºC). Palm oil packed in the fi lm that contained the highest percentage of annatto (1.0%) was the least oxidized during the study period. It was found that, as they increase the losses of phenolic compounds in the formulations of the fi lms, there is a reduction in the peroxide increases the packaged product, thus demonstrating that instead of the product, the compounds of the package’s who are suffering oxidation.
