據(jù)了解，目前加拿大已批準(zhǔn)莧菜紅按照最大限量300ppm的水平（單獨(dú)或與誘惑紅、檸檬黃等色素混合），用于面包、濃縮果汁、風(fēng)味牛奶等食品。

    然而該限量通常高于莧菜紅的實(shí)際用量，而且如果莧菜紅使用量增加，暴露風(fēng)險(xiǎn)會(huì)增大，鑒于此加拿大衛(wèi)生部將莧菜紅單獨(dú)拿出，新制定使用規(guī)定。誘惑紅、檸檬黃等色素的使用規(guī)定不變。

 

    部分原文報(bào)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.
