据了解，目前加拿大已批准苋菜红按照最大限量300ppm的水平（单独或与诱惑红、柠檬黄等色素混合），用于面包、浓缩果汁、风味牛奶等食品。

    然而该限量通常高于苋菜红的实际用量，而且如果苋菜红使用量增加，暴露风险会增大，鉴于此加拿大卫生部将苋菜红单独拿出，新制定使用规定。诱惑红、柠檬黄等色素的使用规定不变。

 

    部分原文报道如下：

 

    Food additives are regulated in Canada under Marketing Authorizations （MAs） issued by the Minister of Health and the Food and Drug Regulations. Approved food additives and their permitted conditions of use are set out in the Lists of Permitted Food Additives that are incorporated by reference in the MAs and published on Health Canada's website. A petitioner can request that Health Canada approve a new additive or a new condition of use for an already approved food additive by filing a food additive submission with the Department's Food Directorate. Health Canada uses this premarket approval process to determine whether the scientific data support the safety of food additives when used under specified conditions in foods sold in Canada.
