氯化鎂

別名鹵片、鹽鹵

是以(yi)水氯鎂石或直接用(yong)制鹽母液為原料制成。

工業氯(lv)化(hua)鎂多用于(yu)化(hua)學(xue)、建材(cai)、冶金(jin)、機械(xie)、交通、醫藥及農業等行業食用氯(lv)化(hua)鎂可(ke)作為食品(pin)添加劑(ji)用于(yu)豆類制品(pin)生產(chan)中峠為穩定劑(ji)或凝固劑(ji)。

    為什么會在(zai)食(shi)品中使用

    在《食品添加劑(ji)(ji)使用(yong)(yong)標準》中(zhong)規定(ding)氯化(hua)鎂可作為穩定(ding)劑(ji)(ji)或凝固劑(ji)(ji)用(yong)(yong)于豆(dou)類制品中(zhong)但不允(yun)許用(yong)(yong)工業品代替食用(yong)(yong)級產品使用(yong)(yong)。

    目前不(bu)法分子違規使用(yong)工業氯(lv)(lv)化(hua)鎂(mei)為一是(shi)用(yong)工業氯(lv)(lv)化(hua)鎂(mei)代替食用(yong)氯(lv)(lv)化(hua)鎂(mei)用(yong)于豆類制品生產中以達到降低成本的(de)目的(de)賠(pei)是(shi)用(yong)工業氯(lv)(lv)化(hua)鎂(mei)浸泡(pao)(pao)木(mu)耳(er)木(mu)耳(er)經浸泡(pao)(pao)后菌朵很大菌葉肥厚感官較好(hao)盠且重量(liang)可增加23倍。

    違規使用(yong)的鑒(jian)別

    使用工業氯化鎂(mei)作為(wei)凝固劑生產(chan)出來的豆制品(pin)色澤(ze)和氣味與合格產(chan)品(pin)沒(mei)有明顯的區別因此鑒(jian)別起來比較困難。

    經工業氯化(hua)鎂浸泡(pao)的(de)木(mu)耳手(shou)掰(bai)時會(hui)有崩裂(lie)的(de)現象邊緣也會(hui)不自(zi)然地朝里卷曲品嘗時會(hui)感覺(jue)到甜味回家泡(pao)開后沒(mei)有木(mu)耳應有的(de)彈(dan)性。

    有何危害

    食品(pin)添(tian)加劑氯化(hua)鎂(mei)適量食用(yong)對人體不會(hui)造成什么傷害但工(gong)業氯化(hua)鎂(mei)因為它其中雜(za)質(zhi)較多且(qie)含有硫酸鹽及各種重金屬(shu)等(deng)有害物質(zhi)因此翠期食用(yong)會(hui)造成急性(xing)(xing)中毒和慢(man)性(xing)(xing)危害可能引起(qi)尿毒癥、膽結(jie)石(shi)、腎結(jie)石(shi)等(deng)疾病。

    違(wei)規使用(yong)的監管

    近年來各級質(zhi)檢部門開展了多次針對非法使用工(gong)業氯化鎂的(de)整治行動但由于木耳銷售有(you)很(hen)大比例是在農貿市場散裝(zhuang)銷售追(zhui)溯較困難這給監(jian)管(guan)工(gong)作造(zao)成了很(hen)大的(de)難度忠(zhong)給了不法分子以可乘(cheng)之機
