Research progress for the contamination of ultra violet stabilizers and absorbers and their determination methods

The wide applications of ultra violet stabilizers and absorbers in industry caused the elevation of the contaminated levels in environmental media and livings. Because of many violet stabilizers and absorbers have estrogenic effects on livings, and more concerns are attracted on them. In order to prevent the aging process of plastic food contact materials, violet stabilizers and absorbers are employed in the process of manufacture. Therefore, these chemicals could migrate into food when the plastic food contact materials were used for food package. The migration quantity needed to be determined to prevent proceeding the limits. In this paper, the research progress for the contaminated level, hazardous effects of ultra violet stabilizers and absorbers was carried to imply that the migration from plastic food contact materials to food could cause food safety problem. Finally, the relative determination methods for ultra violet stabilizers and absorbers were reviewed to prospect the surveillance technique and measures for the ultra violet stabilizers and absorbers in plastic food contact materials.
