Food Addit Contam Part A Chem Anal Control Expo Risk Assess. 2018 Mar;35(3):425-438. doi: 10.1080/19440049.2017.1411619. Epub 2017 Dec 28.
This research investigated the intakes of six intense sweeteners: acesulfame-K (E950), aspartame (E951), cyclamate (E952), saccharin (E954), sucralose (E955), and steviol glycosides (E960) in the diets of Irish adults, using data from the National Adult Nutrition Survey. A food label survey that included products currently available on the Irish market supplemented the analysis. Sweetener intakes were investigated using three different exposure scenarios; beginning with a crude assessment which assumed that all foods permitted to contain the additives of interest always did contain them, and at their maximum permitted level (Tier 1). Refined assessments estimated intakes of the six sweeteners using food consumption data up to brand level with additive occurrence data from a survey of products currently available on the Irish market (Tier 2) and sweetener concentration data (Tier 3). Results of all exposure assessment scenarios demonstrate that intakes of each of the sweeteners of interest by the total population were below the relevant ADI level (mg kg bodyweight), even by high consumers (P99). The three sweeteners consumed in highest amounts were acesulfame-k, aspartame, and sucralose. The main sources of these sweeteners in the diet were 'cider and perry', 'energy reduced and no added sugar (ER and NAS) carbonated flavoured drinks', 'table-top sweeteners', 'dairy products', 'solid food supplements', and 'sauces'. Intakes of the six intense sweeteners are currently not a concern among Irish adults. However, exposure to these chemicals should be monitored on a regular basis due to evolving market and consumption patterns.
本研究利用来自全国成人营养调查的数据，调查了爱尔兰成年人饮食中六种高强度甜味剂的摄入量：乙酰磺胺酸钾（E950）、阿斯巴甜（E951）、甜蜜素（E952）、糖精（E954）、三氯蔗糖（E955）和甜菊糖苷（E960）。一项包括爱尔兰市场上现有产品的食品标签调查对该分析起到了补充作用。使用三种不同的暴露情景对甜味剂摄入量进行了调查；首先是粗略评估，即假设所有允许含有相关添加剂的食品始终含有这些添加剂，且处于其最大允许水平（第1层）。精细评估使用了截至品牌层面的食品消费数据以及来自爱尔兰市场现有产品调查的添加剂出现数据（第2层）和甜味剂浓度数据（第3层），来估计六种甜味剂的摄入量。所有暴露评估情景的结果表明，即使是高消费者（第99百分位数），感兴趣的每种甜味剂的总摄入量均低于相关的每日允许摄入量水平（毫克/千克体重）。摄入量最高的三种甜味剂是乙酰磺胺酸钾、阿斯巴甜和三氯蔗糖。这些甜味剂在饮食中的主要来源是“苹果酒和梨酒”、“低能量且无添加糖（ER和NAS）的碳酸风味饮料”、“餐桌甜味剂”、“乳制品”、“固体食品补充剂”和“调味汁”。目前，六种高强度甜味剂的摄入量在爱尔兰成年人中并非问题。然而，由于市场和消费模式不断变化，应定期监测对这些化学物质的暴露情况。
