臭氧注入聚乙烯包装袋密封消毒一次性餐具的研究
目的 解决塑料一次性餐具、淋膜纸碗等不经清洁直接接触食品的制品出厂时的微生物质量管控缺失的问题。方法 采用臭氧注入聚乙烯包装袋密封消毒的方法, 对一次性餐具阳性样品进行消毒测试, 并参照相应国家标准及检验方法对其总迁移量和脱色试验项目进行测试评估。结果 当O3浓度达到555.6 mg/m3后密封保持4 h, 淋膜纸碗、聚丙烯塑料餐盒、聚苯乙烯塑料勺3种不同材质的一次性餐具均得到了良好的消毒效果。当O3浓度达到555.6 mg/m3后密封保持48 h, 3种不同材质的一次性餐具的总迁移量和脱色试验测试结果符合国家相应标准要求或产品性能未发生明显变化。结论 臭氧注入聚乙烯包装袋密封消毒一次性餐具有可行性, 可为生产者有效管控微生物指标提供参考和借鉴。
Objective To solve the problem of lack of microbial quality control when leaving the factory for products such as plastic disposable tableware and coated paper bowls that directly contact food without cleaning. Methods The method of disinfection in polyethylene sealed bag with ozone injection was used to disinfect the positive samples of disposable tableware, and the total migration and decolorization were tested and evaluated by reference to the corresponding national standards and test methods. Results Seal to hold 4 hours when O3 concentration reached 555.6 mg/m3, paper bowls, polypropylene plastic boxes and polystyrene plastic spoons, three different materials of disposable tableware had good disinfection effect. Seal to hold 48 hours when O3 concentration reached 555.6 mg/m3, total migration and decolorization test results of three different materials disposable tableware meet national standard requirements or no significant change in product performance. Conclusion Disinfection for disposable tableware in polyethylene sealed bag with ozone injection is feasible, which can provide reference for producers to effectively control microbial indicators.
