摘要
纸包装油墨中含有有毒有害物质并可通过包装材料迁移进入内装食品从而危害人体健康。模拟实际印刷条件制作真实油墨迁移单元,研究纸张胶印油墨中4种主要增塑剂(3种邻苯二甲酸酯类增塑剂和近年流行的环保增塑剂乙酰基柠檬酸三丁酯)向奶粉的迁移,考察其在100、70、50、25 ℃的迁移行为,探讨增塑剂的性质及其在纸张中的分布等因素对迁移行为的影响。结果表明:4种增塑剂的最大迁移率在6.7%~67.8%之间。纸包装油墨中增塑剂的迁移防护性能还有待提高。
The safe use of printing materials for food packaging is a major area of investigation. The hazardous substanceslike plasticizers in printing inks can migrate into the food through the packaging material. However, there have beenfew studies reporting the migration kinetics of the the plasticizers to food from ink. In this study, a novel method wasdeveloped for the study of migration of plasticizers from the printing inks through paper to milk powder at 100, 70, 50 ℃ and 25 ℃,respectively and for different contact times ranging from 5 min at 100 ℃ to 40 days at 25 ℃. The inks were offset printed bysimulating the real situation, hadwhich has never been used in migration research. The plasticizers investigated included thecommonly used dibutyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DOP) and a new type of theenvironmentally-friendly plasticizer, acetyl tributyl citrate (ATBC). Gas chromatography coupled with ?ame ionization detector(GC-FID) was used for the determination of ethanol extracts of these plasticizers from both printed paper and milk powder. Theresults showed that the paper did not provide an appropriate barrier against the migration of the plasticizers from printing inks. Themaximum migration of DBP and ATBC reached almost 67.8% while that of DEHP and DOP was about 6.7%. The contact time,the temperature and the properties of the compounds are the factors affecting the real mass transfer.
