| 目的?探究一次性竹木筷中过氧化氢残留情况，评估其潜在的质量安全风险，并提出质量安全提升对策，为完善行业标准及监管措施提供科学依据。方法?
模拟一次性竹木筷在实际使用条件进行过氧化氢迁移试验，采用分光光度法测定蒸馏水中过氧化氢的迁移量，按照危害识别、危害特征描述、暴露量评估和风险表征四个步骤，评估其安全性。结果?实验显示，一次性竹木筷中过氧化氢迁移量为40 ~ 110 mg/kg，常规人群（非婴幼儿）的膳食暴露风险系数为3.3×103% ~ 9.1×103%，远超国际默认安全阈值（20%），一次性竹木筷中过氧化氢残留可能会对人体造成一定的健康风险。 结论 风险评估结论说明一次性竹木筷中过氧化氢残留已构成显著暴露风险，长期使用可能存在安全隐患，亟需纳入食品安全重点监控范畴，建议加强生产管控、完善行业标准、强化市场监管并提高公众认知，竭力保障保障公众人身健康安全。 |

| Objective The residual hydrogen peroxide in disposable bamboo and wood chopsticks was investigated to assess potential quality safety risks, with quality improvement strategies proposed to provide scientific basis for enhancing industry standards and regulatory measures. Methods A migration experiment simulating actual usage conditions was conducted, where hydrogen peroxide migration into distilled water was determined by spectrophotometric method. Safety assessment was performed through four-step process: hazard identification, hazard characterization, exposure assessment, and risk characterization. Results Experimental data revealed that hydrogen peroxide migration ranged from 40 ~ 110 mg/kg. The dietary exposure risk coefficient for general population (excluding infants) was calculated as 3.3×103% ~ 9.1×103%, significantly exceeding the internationally accepted safety threshold (20%). This indicated potential health risks associated with hydrogen peroxide residues. Conclusion The risk assessment concluded that residual hydrogen peroxide in disposable bamboo chopsticks posed significant exposure risks, suggesting potential safety hazards from long-term use. Immediate inclusion in food safety monitoring systems was recommended. Enhanced production control, improved industry standards, strengthened market supervision, and public awareness campaigns were proposed to safeguard public health and safety. |
