对可降解聚乳酸塑料进行生物学安全性评价,为食品包装材料的应用提供依据。参照原中华人民共和国卫生部《化学品毒性鉴定技术规范》中生物学评价的方法和要求,对聚乳酸塑料急性毒性、亚急性毒性试验,致突变毒性(Ames试验、小鼠淋巴瘤细胞突变试验及染色体畸变试验),遗传毒性(睾丸染色体畸变、小鼠精子畸形试验、胎鼠致畸)等系列生物安全性进行研究。结果表明该材料的生物学检测结果均为阴性,提示该材料具有良好的生物学安全性。
Biodegradable polylactic acid plastic biological safety evaluation, provide the basis for the application of food packaging materials. With reference to the methods and requirements of the biological evaluation previously promulgated by the Ministry of Public Health of the People’s Republic of China on the Technical Criteria for the Identification of Chemical Toxicity, the acute toxicity, subacute toxicity test, mutagenicity test (Ames test, mouse lymphoma cell mutation test And chromosomal aberration test), genotoxicity (testicular chromosomal aberration, mouse sperm abnormality test, fetal rat teratogenicity) series of biological safety studies. The results showed that the biological test results were negative, suggesting that the material has good biological safety.
