Candies, chewing gums, dried fruits, jellies, chocolate, and shredded squid pieces imported from 17 countries were surveyed for their aluminum content. The samples were bought from candy shops, supermarkets, and convenience stores, and through online shopping. Sample selection focused on imported candies and snacks. A total of 67 samples, including five chewing gums, seven dried fruits, 13 chocolates, two jellies, two dried squid pieces, and 38 candies, were analyzed. The content of aluminum was analyzed by inductively coupled plasma optical emission spectrometry (ICP OES). The limit of quantitation for aluminum was 1.53 mg/kg. The content of aluminum ranged from not detected (ND) to 828.9 mg/kg. The mean concentrations of aluminum in chewing gums, dried fruits, chocolate, jellies, dried squid pieces, and candies were 36.62 mg/kg, 300.06 mg/kg, 9.1 mg/kg, 2.3 mg/kg, 7.8 mg/kg, and 24.26 mg/kg, respectively. Some samples had relatively high aluminum content. The highest aluminum content of 828.9 mg/kg was found in dried papaya threads imported from Thailand. Candies imported from Thailand and Vietnam had aluminum contents of 265.7 mg/kg and 333.1 mg/kg, respectively. Exposure risk assessment based on data from the Taiwan National Food Consumption Database was employed to calculate the percent provisional tolerable weekly intake (%PTWI). The percent provisional tolerable weekly intake of aluminum for adults (19-50 years) and children (3-6 years) based on the consumption rate of the total population showed that candies and snacks did not contribute greatly to aluminum exposure. By contrast, in the exposure assessment based on the consumers-only consumption rate, the estimated values of weekly exposure to aluminum from dried papaya threads in adults (19-50 years) and children (3-6 years) were 4.18 mg/kg body weight (bw)/wk and 7.93 mg/kg bw/wk, respectively, for 50 percentile consumers, and 6.26 mg/kg bw/wk and 12.88 mg/kg bw/wk, respectively, for 95 percentile consumers.
从 17 个国家进口的糖果、口香糖、果脯、果冻、巧克力和鱿鱼丝被检测其铝含量。这些样品是从糖果店、超市和便利店以及网上购买的。样品选择侧重于进口糖果和零食。共分析了 67 个样品，包括 5 个口香糖、7 个果脯、13 个巧克力、2 个果冻、2 个干鱿鱼丝和 38 个糖果。铝含量采用电感耦合等离子体发射光谱法（ICP OES）分析。铝的定量限为 1.53mg/kg。铝含量范围为未检出（ND）至 828.9mg/kg。口香糖、果脯、巧克力、果冻、干鱿鱼丝和糖果中铝的平均浓度分别为 36.62mg/kg、300.06mg/kg、9.1mg/kg、2.3mg/kg、7.8mg/kg和 24.26mg/kg。一些样品的铝含量相对较高。在从泰国进口的干木瓜丝中发现了最高的铝含量 828.9mg/kg。从泰国和越南进口的糖果中，铝含量分别为 265.7mg/kg 和 333.1mg/kg。基于台湾国家食品消费数据库的数据进行暴露风险评估，以计算暂定每周可耐受摄入量的百分比（%PTWI）。基于总人口的消费率，成年人（19-50 岁）和儿童（3-6 岁）的暂定每周可耐受铝摄入量的百分比显示，糖果和零食对铝暴露的贡献不大。相比之下，基于消费者仅消费率的暴露评估，成年人（19-50 岁）和儿童（3-6 岁）从干木瓜丝中每周摄入铝的估计值分别为 4.18mg/kg 体重（bw）/wk 和 7.93mg/kg bw/wk，对于 50%消费者，分别为 6.26mg/kg bw/wk 和 12.88mg/kg bw/wk，对于 95%消费者。
