湖南省现制饮料中甜味剂膳食暴露及对青少年风险评估

Dietary intake and risk assessment of sweeteners in prepared beverages among adolescents in Hunan province,China

[目的]了解湖南省现制饮料中甜味剂的含量情况以及对青少年的潜在健康风险。[方法]在全省范围内的饮品店采集现制饮料样品850份,采用高效液相色谱法和气相色谱法检测现制饮料中甜味剂含量。结合青少年现制饮料消费情况,对比甜味剂每日允许摄入量(ADI),评估湖南省青少年群体现制饮料中糖精钠、甜蜜素、安赛蜜的暴露水平。[结果]湖南省青少年群体现制饮料甜蜜素的平均每日暴露量及P97.5暴露量分别为0.0248(占ADI的0.230%),0.1570(占ADI的1.430%)mg/kg BW,安赛蜜的平均每日暴露量及P97.5暴露量分别为0.0176(占ADI的0.120%),0.0912(占ADI的0.608%)mg/kg BW,甜味剂的摄入量均低于安全摄入值。[结论]目前,湖南省现制饮料甜味剂膳食暴露量对青少年群体健康造成的风险较低,处于可接受水平。

[Objective]To verify the content of sweeteners in ready-made beverages in Hunan province,China,and the potential health risks to adolescents.[Methods]Total 850 samples of prepared beverages were collected from beverage stores across Hunan province,and the content of sweeteners in ready-made beverages was detected by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS).Combined with the consumption of ready-made beverages among adolescents,the exposure levels of sodium saccharin,cyclamate and acesulfame in ready-made beverages among adolescents in Hunan province were evaluated.[Results]The average daily exposure and P97.5 exposure of ready-made beverage cyclamate in adolescents in Hunan Province were 0.0248 mg/kg BW(0.230%of ADI)and 0.1570 mg/kg BW(1.430%of ADI),respectively,and the average daily exposure and P97.5 exposure of acesulfame were 0.0176 mg/kg BW(0.120%of ADI)and 0.0912 mg/kg BW(0.608%of ADI),respectively.The intake of sweeteners was below the safe intake value.[Conclusion]At present,the dietary exposure of freshly prepared beverage sweeteners in Hunan Province poses a low risk to the health of adolescents and is at an acceptable level.
