Estimates of dietary exposure of children to artificial food colours in Kuwait

To assess the intake of artificial food colour additives by 5-14-year-old children in the State of Kuwait, a 24-h dietary recall was conducted twice on 3141 male and female Kuwaiti and non-Kuwaiti children from 58 schools. The determination of colour additives in 344 foods items consumed was performed using high-performance liquid chromatography with diode array detector. A comparison with the Food and Agriculture Organization and World Health Organization acceptable daily intakes (ADIs) was undertaken to evaluate the potential risk associated with the consumption of artificial colour additives by children in Kuwait. The results indicated that out of nine permitted colours, four exceeded their ADIs by factors of 2-8: tartrazine, sunset yellow, carmoisine and allura red. Further, follow-up studies to provide insight into potential adverse health effects associated with the high intakes of these artificial colour additives on the test population are warranted.     

Food colors: Existing and emerging food safety concerns

Food colors are added to different types of commodities to increase their visual attractiveness or to compensate for natural color variations. The use of these additives is strictly regulated in the European Union, the United States, and many other countries worldwide. There is a growing concern about the safety of some commonly used legal food colorants and there is a trend to replace the synthetic forms with natural products. Additionally, a number of dyes with known or suspected genotoxic or carcinogenic properties have been shown to be added illegally to foods. Robust monitoring programs based on reliable detection methods are required to assure the food is free from harmful colors. The aim of this review is to present an up to date status of the various concerns arising from use of color additives in food. The most important food safety concerns in the field of food colors are lack of uniform regulation concerning legal food colors worldwide, possible link of artificial colors to hyperactive behavior, replacement of synthetic colors with natural ones, and the presence of harmful illegal dyes—both known but also new, emerging ones in food. The legal status of food color additives in the EU, United States, and worldwide is summarized. The reported negative health effects of both legal and illegal colors are presented. The European Rapid Alert System for Food and Feed notifications and US import alerts concerning food colors are analyzed and trends in fraudulent use of color additives identified. The detection methods for synthetic colors are also reviewed.     

Exposure assessment to synthetic food colours of a selected population in Hyderabad, India

An exposure assessment of synthetic food colours was carried out among 1-5- and 6-18-year-old individuals by the food frequency method. Children had an intake of solid food consumption in the range 2-465 g day^-1 and liquid food consumption in the range 25-840 ml day^-1 with added colours. Among the eight permitted colours in India, six were consumed by the subjects of the study. The intakes of some subjects exceeded the acceptable daily intake for colours such as tartrazine, sunset yellow and erythrosine, which is 7.5, 2.5 and 0.1 mg kg^-1 body weight, respectively. Therefore, a uniform permissible limit of 100 mg kg^-1 prescribed under the Prevention of Food Adulteration Act in India for all foods is not justified. The limits need to be revised according to the Codex Alimentarius Commission, which permits different maximum levels of additives to various food categories based on both the extent of consumption and the technological justification for its use.     

Encapsulation of carthamin and safflor yellow B in calcium alginate beads — technical stabilization of the colours

New techniques were introduced to stabilize the royal red colour of carthamin and the orange yellow colour of safflor yellow B. Carthamin and safflor yellow B were enclosed separately into calcium alginate capsules, through which the colours were protected from serious bleaching. Coating of the carthamin beads with safflor yellow B membrane resulted in further reducing the loss of colour by about 25%. the data are evaluated for the practical application of the bio-dyes in food processing.

Recent trends in the use of food additives in the United Kingdom

The E number system for food additives was introduced in the 1960s and the E was intended to reassure consumers that permitted additives were safe. In the 1980s full ingredient declarations had to be provided on food products for the first time and manufacturers were permitted to use either the name or the number of the additive on the ingredient list. This paper outlines some of the trends in the sourcing, use and labelling of additives since the introduction of full ingredient listing. Generally, sourcing has become more global with a large number of suppliers being based in China. From an initial use of E numbers in ingredient lists, manufacturers are increasingly using the names of additives. This trend is being extended to avoid the use of anything the consumer might consider an additive, particularly in connection with colours and preservatives. Specifically, the colours used in the Southampton study on the impact of food colours on hyperactivity in children have largely been replaced by colouring foodstuffs, and the preservative used in the study, sodium benzoate, has been replaced by potassium sorbate in the majority of soft drinks. © 2014 Society of Chemical Industry

食品中缩节胺形成机制研究进展

缩节胺是我国农业上普遍使用的一种植物生长调节剂,对棉花、番茄等农产品的生长、发育具有很好的促进能力。然而植物生长调节剂和其他农药一样,也存在某些毒性危害,但缩节胺的毒性和残留在我国并没有得到足够的重视。随着毒理学的发展,科研人员发现部分植物生长调节剂会有致癌作用。同时研究发现在特定的食品加工过程中,由于高温等操作会导致缩节胺的自然形成。食品中形成的缩节胺已成为影响食品安全的重要潜在因素,也吸引了人们对其危害的日益关注。本综述主要探讨了食品中缩节胺的形成机制,阐述参与缩节胺生成所需的甲基供体,总结其毒性研究,以期为缩节胺的控制奠定理论基础。     

食品中偶氮类色素检测方法的研究进展

食品在加工的过程中容易丢失原本的颜色,食品加工者为了使食物看起来更美味,向其中添加廉价的合成色素。但偶氮类合成色素对人体存在致癌风险,许多国家已禁止在食品中添加偶氮类合成色素,并严格监管该类食品在国内的流通及进出口。本文综述了食品行业中针对偶氮类合成色素的各种检验方法,以期为食品安全监督检测相关机构提供参考。当前国内外食品中禁用偶氮色素检验方法主要包括光谱法、色谱法、电化学、酶联免疫法、化学发光及其他检测方法等,这些方法在方便、快捷、准确等方面取得了较大的进步,但是仍然面临一些问题,如灵敏度低、定性能力差、假阳性率高,成本高和前处理复杂等。因此开发操作简便、高通量的检测技术和仪器将是未来的发展方向。
