Nitrate and nitrite are the most applied food additives to inhibit microbial growth. The main risk of nitrate and nitrite presence in food is the formation of nitrosamines during food preparation and digestion. However, dietary intake of nitrite and nitrate from food has potential cardiovascular benefits. Accordingly, 160 samples from meat and poultry were randomly collected to evaluate the level of occurrence nitrate and nitrite using an HPLC method and estimate the daily intake (EDI) of Egyptian adults and children. The levels of nitrate and nitrite ranged between 1.3-557 mg/kg and 6-812 mg/kg, respectively. The EDI was compared with the accepted daily intake (ADI) represented in the hazard index (HI) scale. The nitrite results clarify that all HI values were above 1 for all commodities, while for nitrate it exceeded 1 only for canned meat and basturma, when consumed by children.
硝酸盐和亚硝酸盐是最常用的食品添加剂，以抑制微生物的生长。硝酸盐和亚硝酸盐在食品中存在的主要风险是在食品制备和消化过程中形成亚硝胺。然而，从食物中摄入亚硝酸盐和硝酸盐对心血管有潜在的益处。因此，随机采集了 160 份来自肉类和家禽的样本，使用 HPLC 方法评估硝酸盐和亚硝酸盐的发生水平，并估算埃及成年人和儿童的日摄入量（EDI）。硝酸盐和亚硝酸盐的水平分别在 1.3-557 毫克/千克和 6-812 毫克/千克之间。将 EDI 与ADI（危险指数（HI）量表中的接受日摄入量）进行了比较。亚硝酸盐的结果表明，所有商品的所有 HI 值均高于 1，而对于硝酸盐，当儿童食用罐头肉和basturma 时，其值仅超过 1。
