h*****7 发帖数: 2120 | 1 我在网上查 infant formula,碰到有人抱怨formula (including organic infant
formula) 里的 DHA/ARA 都是用一种toxic hexane (己烷) 提炼的(Hexane is a
neurotoxin and a hazardous air pollutant).
我不是学化学的,不太懂。有人懂这个么?那个 infant formula 没这个?那大人吃的
prenatal, milk 里的 DHA 也是这么提炼的?有多危险? | p********5 发帖数: 7433 | 2 任何东西,量的问题。
多了,水都会害死人。
少了,砒霜都能治病。
你问的这些东西的含量,肯定很低,对你的身体没有关系。
怀宝宝,喂宝宝,实验室毒得多的东西多了去了,两个宝宝还好。 | h*****7 发帖数: 2120 | 3 怪不得现在的小孩毛病这么多。上网查了一下, Baby's Only Organic 不是用有毒化
学药剂提炼的。可惜只有toddler formula.网站提示,consult pediatrician for
under 1 year old. | l******o 发帖数: 1864 | 4 我是制药的,hexane(己烷)因为比较毒,所以最后药物检验时要求含量很少。为了减
少除hexane(庚烷)的费用,我们现在化学合成的时候都改用heptane了。说明正规食
品和药品都设有hexane含量标准,超标了不合格的。至于厂家使用hexane提取,最后要
花钱再除hexane,那是他们自己的事。 | h*****7 发帖数: 2120 | 5 根据我的研究 (主要是网上搜寻),有组织/人打电话询问,厂方回答,hexane(己烷
)会自己挥发 before it reaches customers. 这说明他们没有花钱除 hexane?!
网上搜来的:
FDA has not approved use of this type of DHA/ARA extracts (however, they
have not prohibited its use). Imagine that! The same agency that approves
cloned food based on very limited data, did not approve these extracts due
to negative health impacts founds in several studies -- I don't know about
you, but that surely gives me reason to pause before using such products.
These extracts do not fall within the standards for use in organic foods;
however, upon petition to the USDA National Organic Program to use it in
organic foods Martek received no response. In such a case, no response would
indicate that the ingredient is NOT approved for use in organic food;
however, some companies are putting it into organic foods anyway: Happy Baby
organic baby food, Horizon and Stremick’s organic milk, and NuGo organic
nutrition bars are examples, so it will require additional work to avoid
said ingredients. This usage is ILLEGAL and Cornucopia is petitioning to get
it stopped.

| l******o 发帖数: 1864 | 6 对不起,收回我想当然的推论。其实我对食品不太清楚,可能没有药品监管得严格吧。
hexane是非常容易挥发的,做化学实验的人都知道,洒到桌子上一些,几分钟就不见了
,但是根据产品的性质还是可能会有残留。有些化合物,提纯过程中接触到hexane,就
是很难除净,毒性大的东西标准又高,最后那点残余靠自然挥发达不到FDA的标准的。
要加热啦重结晶啦或者和没有毒的溶剂共沸啦来除。
至于除hexane的费用,在药厂里,即使是自然挥发也会通过废气管道,处理费气费液都
是要钱的。更别说为达到标准用的其他程序的钱了。食品业不清楚。
