High consumption of trans-fatty acids (TFAs) is introduced as dietary risk factor of cardiovascular diseases (CVDs). The accuracy of the information shown on the traffic light (TL) labelling has a significant influence on consumers to reduce TFA content in foods. This study is conducted aiming to determine the TFA content in traditional sweets distributed in Isfahan, Iran. Furthermore, the accuracy of the amount of TFAs on TL was considered by comparing it with the experimentally analyzed values.
In this cross-sectional study, a total of 99 Iranian traditional sweets with a TL label were randomly collected from confectionary shops located in Isfahan. TFAs were analyzed by gas chromatography (GC).
TFAs were detected in all samples with the total average of 1.6 ± 0.3% in total fat (range of 0.040 ± 0.001 to 7.900 ± 1.100%). More than half of the samples had less than 2% of TFAs in the total fat. Overall, 81.8% of the studied products with TL labelling showed a discrepancy in the TFAs in the values analyzed in laboratory.
In the present study, the discrepancy of TFAs in the experimentally measured values with TL food labelling was observed in more than 80% of Iranian traditional sweets. Most of the samples contained less than 2% of TFAs that is defined as a limit in Iran Food and Drug Administration (IFDA). These findings could be alarming for the consumers of this kind of products.
高摄入反式脂肪酸（TFA）被认为是心血管疾病（CVD）的饮食风险因素。交通信号灯（TL）标签上显示的信息准确性对消费者减少食品中TFA含量有重大影响。本研究旨在确定伊朗伊斯法罕市销售的传统糖果中的TFA含量。此外，通过将TL上TFA含量与实验分析值进行比较，评估TL标签上TFA含量信息的准确性。
在这项横断面研究中，从伊斯法罕市的糖果店随机收集了99种带有TL标签的伊朗传统糖果。采用气相色谱法（GC）分析TFA。
所有样品均检测出TFA，总脂肪中TFA平均含量为1.6±0.3%（范围为0.040±0.001至7.900±1.100%）。超过一半的样品总脂肪中TFA含量低于2%。总体而言，81.8%带有TL标签的研究产品在实验室分析的TFA值上存在差异。
在本研究中，超过80%的伊朗传统糖果在实验测量值与TL食品标签的TFA含量上存在差异。大多数样品的TFA含量低于2%，这是伊朗食品药品管理局（IFDA）规定的限量。这些发现可能会给这类产品的消费者敲响警钟。
