摘　　要：目的了解我国茶叶包装材料的使用情况,构建不同类别茶叶不同食品接触材料的接触面积/体积比(S/V)基础数据库。方法采集市场销售的不同包装和类型的7大类茶叶,通过直接测量法及应用3D表面积测量仪获得413份茶叶样品的接触面积,结合不同类别茶叶产品的质量、规格等数据信息,计算其S/V。结果茶叶的接触材料均为单一材质,不同类别茶叶接触材料的S/V的平均值为93.0 dm^(2)/kg,范围为3.5~595.6 dm^(2)/kg。99.8%(412/413)的茶叶接触材料S/V≥6.0 dm^(2)/kg,87.2%(360/413)的S/V介于6.0~200.0 dm^(2)/kg之间。结论我国大部分市售茶叶的S/V大于欧盟评估时采用的6.0 dm^(2)/kg,利用本次调查研究获得的参数将会降低食品接触材料风险评估中的不确定性。Objective To study the use of packaging materials for tea in China and establish the database of surface area to volume ratios(S/V)of different food contact materials for different types of tea.Methods Seven categories and 413 tea samples with different packaging forms were purchased from markets and online stores.Food contact surface area of each sample was determined by direct measurement or via 3D surface area measuring instruments.The S/V was calculated based on the food contact surface area and the quality or specification data of the tea products.Results All the contact materials for tea were made of a single material,and the mean S/V was 93.0 dm^(2)/kg,ranging from 3.5 to 595.6 dm^(2)/kg.99.8%(412/413)of the S/V was equal or higher than 6.0 dm^(2)/kg,and 87.2%(360/413)was in the range of 6.0-200.0 dm^(2)/kg.Conclusion The S/V of most commercially available tea products in China was higher than 6.0 dm^(2)/kg,a parameter used for risk assessment by European Food Safety Authority(EFSA).Therefore,using the S/V constructed by this investigation can decrease the uncertainty in the food contact material risk assessment.
