一、無碘鹽的碘含量多少

為了補碘(dian)(dian)(dian)(dian)，市面上的鹽(yan)(yan)通(tong)常會添加(jia)碘(dian)(dian)(dian)(dian)酸鉀，這(zhe)種(zhong)鹽(yan)(yan)也叫(jiao)加(jia)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)，加(jia)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)一(yi)般每100克(ke)(ke)鹽(yan)(yan)中，含碘(dian)(dian)(dian)(dian)量為2500微克(ke)(ke)左右；不(bu)過(guo)對于部分不(bu)需要從鹽(yan)(yan)中攝入碘(dian)(dian)(dian)(dian)的人來(lai)說，會食用無(wu)(wu)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)，那(nei)么(me)無(wu)(wu)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)是一(yi)點碘(dian)(dian)(dian)(dian)都沒(mei)有嗎(ma)？無(wu)(wu)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)會不(bu)會含有碘(dian)(dian)(dian)(dian)呢？

鹽(yan)(yan)(yan)的(de)(de)(de)主要成分是(shi)氯(lv)化鈉，鹽(yan)(yan)(yan)中的(de)(de)(de)碘(dian)含(han)量(liang)(liang)是(shi)額外添加的(de)(de)(de)，無碘(dian)鹽(yan)(yan)(yan)一般碘(dian)含(han)量(liang)(liang)為(wei)0；不(bu)過也有例外的(de)(de)(de)情(qing)況(kuang)，鹽(yan)(yan)(yan)有海(hai)(hai)鹽(yan)(yan)(yan)、井(jing)鹽(yan)(yan)(yan)、礦(kuang)鹽(yan)(yan)(yan)等多種，其中無碘(dian)海(hai)(hai)鹽(yan)(yan)(yan)一般是(shi)指未加碘(dian)的(de)(de)(de)海(hai)(hai)鹽(yan)(yan)(yan)，雖然沒有額外加碘(dian)，不(bu)過海(hai)(hai)鹽(yan)(yan)(yan)中本身會(hui)有一定的(de)(de)(de)天然碘(dian)含(han)量(liang)(liang)，這(zhe)種無碘(dian)鹽(yan)(yan)(yan)通常會(hui)標記，碘(dian)含(han)量(liang)(liang)低于(yu)5mg/kg。

二、無碘鹽是不是不咸

食(shi)鹽(yan)是(shi)家庭不可(ke)或(huo)缺(que)的調料，對于高碘地區(qu)或(huo)需要控制碘攝入的特殊疾病患者來說，可(ke)以(yi)考慮(lv)吃無碘鹽(yan)。鹽(yan)提(ti)供(gong)的是(shi)咸(xian)味，那么(me)無碘鹽(yan)有咸(xian)味嗎(ma)？

實際上，無碘鹽和普通(tong)的加(jia)(jia)碘(dian)鹽在咸(xian)(xian)(xian)度(du)方面沒有什么(me)太大的區別，甚至某種程(cheng)度(du)上，無碘(dian)鹽還要(yao)稍微(wei)咸(xian)(xian)(xian)一些，因為(wei)鹽咸(xian)(xian)(xian)不咸(xian)(xian)(xian)跟加(jia)(jia)不加(jia)(jia)碘(dian)沒有關系(xi)，主要(yao)看的是(shi)氯(lv)(lv)化(hua)鈉的含量，無碘(dian)鹽是(shi)純鹽，不添加(jia)(jia)碘(dian)酸(suan)鉀，氯(lv)(lv)化(hua)鈉的含量比加(jia)(jia)碘(dian)鹽還要(yao)高一些，因此咸(xian)(xian)(xian)度(du)會更高，使用無碘(dian)鹽的時候可(ke)以(yi)稍微(wei)少放(fang)一些鹽。

總的來說，無(wu)碘鹽(yan)并不是不咸，它和加碘鹽(yan)的味道沒(mei)有太大區(qu)別，如果不想吃太咸的話，可(ke)以考慮食用(yong)低(di)鈉(na)鹽(yan)。
