用储奶袋保存母乳安全吗?关键在于储存方法--亲稳网络舆情监控室
2013-05-11

  许多即将恢复工作的哺乳妈妈总会遇到这样一个烦恼:母乳喂养。储奶袋的出现替她们解决了许多后顾之忧,然而,她们又有了新的困惑。请关注——用储奶袋保存母乳安全吗?

许多即将恢复工作的哺乳妈妈总会遇到这样一个烦恼:breastfeeding.The emergence of milk storage bag for them to solve many of the trouble back at home,however,They have the new confusion.Please attention - with the milk storage bag to save breast milk safety?

  储奶袋,又名母乳保鲜袋,是一种食品包装用的塑料产品,主要用于储存母乳。妈妈们可以在母乳充足时将乳汁挤出,装在储奶袋中进行冷藏或冷冻,以备将来奶水不足或因工作等原因无法按时为孩子哺育时使用。因为储存时间长和其他一些特殊的设计,储奶袋受到了职场妈妈的青睐。不过,也有很多妈妈疑虑什么样的储奶袋才安全?

储奶袋,Also known as fresh milk bags,Is a kind of food packaging plastic products,Mainly used for the storage of breast milk.The breast milk when mothers can be abundant in human milk,In a refrigerated or frozen milk storage bag,For future milk supply or can't on time due to work of nurture for children.Because of the储存时间长and其他一些特殊的设计,Store milk bags got the favour of working mothers.but,Mother also has a lot of doubts about what it is safe to store milk bags?

  

纳米银”只是一种噱头 "Nano silver"Is just a gimmick

  储奶袋材质是否安全,正成为哺乳期妈妈们关注的焦点。

储奶袋材质是否安全,Is the focal point of the lactating mothers.

  有一位妈妈反映,使用含纳米银的储奶袋后,解冻后的奶变味了。对此,有网友专门发文提醒妈妈们,不要购买纳米银储奶袋。

有一位妈妈反映,After using nanometer silver store milk bags,Thawed milk sour.For this,Some special post to remind mothers,Don't buy milk storage bag silver nanoparticles.

  “纳米银,包括银离子,都具有杀菌的功能,但是杀菌效果如何还要看具体的产品,因为银的杀菌效果与用量是密不可分的。纳米银储奶袋中的母乳变味,可能有很多原因。首先,纳米金属一般具有较高的活性,具有催化某些反应的能力,可能会产生一些意想不到的反应。其次,奶本身在存放过程中也会发生变化,只是速度很慢。这种情况需要专门检测才能知道发生了什么变化。但可以推测,变味的奶中有含硫化合物,含硫化合物一般具有特殊的味道。”北京化工大学材料科学与工程学院的徐日炜副教授在接受科技日报采访时指出,“纳米银的毒性近期一直受到关注,纳米金属因为尺寸很小,容易与细胞相互作用,可能存在风险。因为毒性大小是与接触量有关的,如果在安全剂量范围内,则无需太担心。”

"Nano silver,Including the silver ions,All has the function of sterilization,Bactericidal effect but how to also look at specific product,Because of bactericidal effect of silver and the dosage is inseparable.Nano silver store milk sour milk in the bag,There could be many reasons.First of all,Nano metal has higher activity in general,Has the ability of some catalytic reaction,Is likely to result in some unexpected reactions.The second,Milk itself will also change during storage,Just very slow.This kind of situation need special tests to know what has changed.But it can be speculated that,Sour milk of sulfur-containing compounds,Sulfur compounds are generally has a special flavor."Beijing chemical university associate professor of materials science and engineering college of Xu Rihui said in an interview with science and technology journal,"Of silver nanoparticles toxicity has been concerned recently,Nano metal because the size is very small,Easy to interact with cells,There may be a risk.Because of the toxicity is related to exposure,If the safe dose range,You do not need to worry too much."

  而此前北京大学前沿交叉学科研究院和中国食品药品检定研究院曾对纳米银的安全性进行过评价,指出“纳米银有潜在的生殖毒性和遗传毒性,细胞毒性和剂量成分相关。”

而此前北京大学前沿交叉学科研究院and中国食品药品检定研究院曾对Nano silver的安全性进行过评价,Pointed out that"Nano silver有潜在的生殖毒性and遗传毒性,细胞毒性and剂量成分相关."

  北京化工大学材料科学与工程学院的励杭泉教授表示:“储奶袋的材质本身是没有问题的,保鲜母乳的关键在冷冻,而不在储奶袋。使用洁净的普通塑料袋照样可以保存4个月,不要让厂家偷换概念。纳米银理论上是可以杀菌的,但是价格不菲,厂家更多的只是为了达到宣传的效果。”

北京化工大学材料科学与工程学院的励杭泉教授表示:"Milk storage bag of the material itself is no problem,Key in the frozen fresh milk,Not in store milk bags.Use clean ordinary plastic bags can save 4 months,Don't let the manufacturer to steal.Silver nanoparticles are theoretically can sterilization,But the price does not poor,Manufacturer's more just to reach the effect of propaganda."

  

正规储奶袋是安全的 Regular milk storage bags are safe

  对于储奶袋的安全性,徐日炜指出:“只要生产厂商是严格按照卫生标准制作的,没有乱加东西,一般就不会有问题。”他解释:“储奶袋的材质主要是聚乙烯,也就是通常所说的PE。它是一种最广泛使用的塑料。有些储奶袋标注的材质LDPE(低密度聚乙烯)或LLDPE(线性低密度聚乙烯)都是聚乙烯的一种,只是密度和结构不一样,但在安全性上没有太大差别。有的储奶袋还会加入PET,使它的阻隔性更好一些。这些材质本身都没有问题,关键要看添加剂是否安全。”

对于储奶袋的安全性,Xu Rihui pointed out:"As long as the manufacturer is in strict accordance with the hygiene standards,Don't mess with things,Generally there will be no problem."He explained:"Milk storage materials mainly is the polyethylene bags,Known as PE.It is one of the most widely used plastics.Some milk storage bag label the material of LDPE(Low density polyethylene)Or LLDPE(Linear low density polyethylene)Is a kind of polyethylene,只是密度and结构不一样,But not much difference in safety.Some milk storage bags will also join the PET,Make it a better barrier property.The material itself, there is no problem,The key to see whether the additive is safe."

  徐日炜进一步指出:“很多人害怕塑料产品中添加双酚A,双酚A确实有毒,而以聚碳分子作为原料的产品在一定的温度条件下,可能会释放出双酚A,不过聚乙烯、PET等都不会有这个问题,现在的产品一般都会标注是否含双酚A,在选择时要多加注意。”

徐日炜进一步Pointed out that:"Many people fear that bisphenol A is added to the plastic products,Bisphenol A are poisonous,With polyethylene carbon molecules as raw materials of products under the certain conditions of temperature,May release bisphenol A,but聚乙烯/PET, will not have this problem,Products now are generally indicate whether contains bisphenol A,When the choice must pay more attention."

  “虽然储奶袋材质本身没有问题,但不同品牌的产品仍然存在质量差别,因此,应选择一些生产标准更高的厂家产品。如果制作过程比较精细的话,很多问题是可以避免的。”徐日炜建议。

"Although milk storage bag material itself has no problem,But the quality of different brand products still exist differences,so,Should choose some manufacturer of higher standard products.If the process is fine,A lot of problems can be avoided."Xu Rihui advice.

  也有妈妈建议:一周之内所有储奶袋的效果都差不多,但是两周之后就可以看出不同了。因此在选择之前,可以先试验两周,再决定最后选择哪个品牌的储奶袋。

也有妈妈建议:Almost all store milk bag effect within a week,But after two weeks you can see the different.So before choosing,To test for two weeks,And then make a decision finally choose which brand of milk storage bag.

  

关键在于储存方法 Is the key to store method

  最近有网友在母婴论坛上爆料:还未使用过的储奶袋有异味,有的储奶袋冷冻之后袋子易裂开。一位来自河南的网友发帖称,使用某品牌的储奶袋后,母乳的颜色发黄了,还有的发蓝;而颜色没变的母乳味道尝起来也怪怪的,像豆浆的味道,还有些酸味。

最近有网友在母婴论坛上爆料:Haven't used milk storage bag is faulty,Some milk bag bag is easy to crack after frozen storage.A netizen from henan post said,After using a certain brand of milk storage bag,Breast milk yellow color,There is the blue;And the color did not change milk flavor taste is strange,Like the taste of soy milk,Still have some sour.

  对此,徐日炜解释,袋子裂开是因为使用的材料低温性能差,低温时变脆,受力后就容易裂开。而对于储奶袋存有异味的原因,徐日炜认为:“保鲜袋类的产品通常会采用射线消毒,这种高强度的粒子束在杀死细菌的同时也会留下异味。除此之外,为了使油墨印刷在PE表面获得足够的粘接,会对其表面进行氧化,这也会产生异味。”

For this,Xu Rihui explain,Break bag because the materials used in cryogenic performance is poor,Low temperature time-varying crisp,Is easy to crack after stress.For milk storage bags have peculiar smell,Xu Rihui think:"Bags, products usually adopt radiation disinfection,这种高强度的粒子束在杀死细菌的At the same time也会留下异味.In addition to this,In order to make the ink printing on the surface PE get enough glue,On the surface of oxidation,It also can produce peculiar smell."

  “如果奶中的部分分子发生了变化,可能是有材料进入了奶中,比如说颗粒分散到奶中,形成了特殊的结构,就会使其显色。这类奶建议不要再食用。”徐日炜说。

"If milk changed part of the molecule,May have a material into the milk,Such as particle dispersion in the milk,Formed a special structure,Will make its color.Advice: don't eat this kind of milk."Xu Rihui said.

  励杭泉认为,母乳储存的关键在于冷冻方法,而不在储奶袋。如果使用过程中操作不当,母乳依然会面临被破坏的风险。

励杭泉认为,Stored breast milk is the key to freezing method,Not in store milk bags.If you use the improper operation in the process,Breast milk will remain at risk of destruction.

  徐日炜建议,储奶袋最好不要循环使用,因为“塑料本身的分子是会运动的,并且其运动范围很大,这样就会有东西黏附在上面,这些东西可能会发生质变;塑料制品又不可能完全清洗干净。因此循环使用安全风险就会增大。”

Xu Rihui advice,Milk storage bags had better not be recycled,Because of the"The plastic itself is movement of molecules,And its movement range is very large,So there will be something attached on it,These things can happen qualitative change;Plastic products and can't completely clean.So cycle use safety risk will increase."

  有网友建议:因为奶和水会分离,所以加温的时候,一定要先摇一摇,再用温水泡,不要直接加热。在冰箱中保存的时候,尽可能直立放置,这样可以避免袋子泄漏造成污染,并且最好不要和其他食品放在一起。“其实最好还是给宝宝喝新鲜的母乳,如果一定要冷冻母乳的话,冷冻的时间也不宜太长,因为就算母乳没有变质,长时间冷冻的母乳宝宝也不太爱喝。”她建议。

有网友建议:Because of the奶and水会分离,So turn up the heat,Be sure to shake first,With warm water to soak,Do not heat directly.Kept in a refrigerator,Stand as much as possible,So that you can avoid leakage pollution caused by the bag,并且最好不要and其他食品放在一起."Actually it is better to drink fresh milk for your baby,If must be freezing mother's milk,Frozen time also shoulds not be too long,Because there is no deterioration even mother's milk,Long also not too love to drink frozen breastfed babies."She suggested that.
