Recently milk power contaminated by melamine,that impacts chinese markets.some of this melamine contain in ppm level.why?what's reasons?there is no report.I rearched chemical abstrats from 2008 to 14th.It's found that impurity come from urea,a feed for cow.(CA 149 31088 etc).my suggestion is to control urea's impurity melamine.It's easily than milk.
最近报导了中国市场乳品中含三聚氰胺向题,其量在ppm水平,耒源并无报导.经查CA证实,系从牛饲料尿素,富集到牛乳.要控制牛乳中三聚氰胺,可以从控制尿素中的三聚氰胺杂质含量,要容易分析.
