繼伊利奶粉汞超標事件之后,又一家乳品企業(yè)出現(xiàn)質(zhì)量問題。近日有消費者在微博上爆料光明部分優(yōu)倍奶混入了清洗用堿水,隨后光明乳業(yè)在其官網(wǎng)發(fā)布解釋說明,并召回產(chǎn)品。
請看中國日報網(wǎng)報道:
An investigation conducted by the bureau Wednesday found that food-grade lye that was used to clean pipes had leaked into and contaminated a production line at one of the company's plants on Monday, a bureau spokesman said early Thursday.
上海市質(zhì)監(jiān)局發(fā)言人周四早上稱,該局周三對此事做了調(diào)查,發(fā)現(xiàn)光明乳業(yè)某廠周一進行生產(chǎn)時,不慎將用來清洗管道的食用級堿水滲入生產(chǎn)線上的牛奶中。
上面報道中的food-grade lye就是食用級堿水,食用堿常被用作食品curing agent(固化劑)和肉類tenderizer(嫩化劑)。食用堿不同于工業(yè)用堿,后者腐蝕性極強,一般用做drain opener(下水疏通劑)和detergent(清潔劑)。
從2008年melamine milk(三聚氰胺奶)事件開始,國內(nèi)幾大乳企頻頻爆出過質(zhì)量門。從去年年底的蒙牛牛奶aflatoxin(黃曲霉毒素,一種致癌物)超標,再到近期伊利baby formula(嬰兒配方奶粉)和whey powder(乳清粉)含excessive mercury(汞超標),讓國人對國產(chǎn)乳制品的信心急速下滑。
