Distilled water: Does it expire?

[nirdle_phogi]

---

ang plastic na botelya maoy ma-expire.. labi na kun mainitan..

[mr_kyme]

I'm curious about the brand vit water.

[yerl88]

the question is ma-expired ba or dili?

the answer is YES, kay ngano? tungod sa iyang hydrogen power gamay almost 2-8.
Simple.

wala man expiry date ang water oi.. were talking about the decomposition of the plastic.. dire sa ato country, low quality plastic man ato gamit to contain water.. try gani ninu ibutang sa freezer ang bottled water for even just a week, molain na lage ang lasa...

the best containers for water is..... glass bottle (no color) and clay jar.. all natural. hehehehe.. nothing beats nature kc..

changes in water taste done in PET bottles usually happens when the product is not well stored. PET or poly-ethylyne terephthalate is an oil-based material and exposure to warm climates at longer periods causes it to degrade.

water (non-distilled) usually changes taste after freezing. it is due to many factors: one is sedimentation of particles and dissolve solids. another is death of some organic bacteria present. coliform makes the water a bit sweet. hehe. and also if chlorinated, chlorine expires thru a short time.

According to the International Bottled Water Association, the FDA has not established a shelf life for water, so you can store those bottles indefinitely. As long as the packaging is intact and unopened, you shouldn't need to worry about any type of bacteria or microorganisms growing in the water. If the bottle has been opened, however, it can grow bacteria and algae if it is not consumed within 2 weeks.

The reason why water taste different after long period of storage is that, water picks up flavors from its packaging. These flavors, combined with warm storage temperatures, contribute to the "generation of musty tastes. It won't affect your health anyway.

Try to transfer the contents to a glass bottle, and see if the taste is similar after a few days/weeks. Beside this, let the remaining distilled water remain in the plastic container (your control).

People have totally forgotten the scientific method (experimentation).

I like jayredd's answer than rodions.

I agree. We are not talking about differences in the taste. It could taste different and yet still not "expired". Otherwise, there should be a standard taste for all bottled waters and there is none.

So whether you are drinking Evian, Volvic or the carbonated Perrier or the local Viva, the differences in taste is not the determinant of being expired.

In Rodion's proposed experiment, there could be differences in the taste between the control and the portion transferred to a different container but it does not prove that one or the other is expired.

Sorry, but it's not a scientific method to address the question at hand. It could only prove that taste could be altered depending on the container.

this is quite an interesting topic...

if i may add, why are there expiry sa mga distilled or even mineral bottled water is --one factor that affect is its packaging which is plastic.. if you have noticed in your plastic bottles, there's a corresponding number incased in the recycled sign... most of the bottled water ryt now is using number 1 bottles... it does not necessarily mean that one-time use lang (though it's highly encouraged na one-time use because of probable bacterial infestation - labi nang sige ta lips to lips sa bottle...)... the number there actually represents the number (sort of code) of the kind of plastic being used (and i think there are 7 types of plastics used for industrial purposes...) Plastics has the tendency to LEACH - meaning some chemicals from the container tends to transfer to the liquid especially when heat is involved.. and so, if madugayan ang water plus a hot environment, expected mo-lain ang taste sa water plus again, distilled water is known to have a pH of about 5-5.8 (in other words, its quite acidic)... and distilled as a harmful type of water... that would in another thread siguro....

hope this can help / add to the information above...

Agree! kaau ko nmo brad.

Its not that water has change its chemical properties. Its the container that contaminates the water.

oh yeah.. i've tried it.. we left our house for a 1 week vacation, then when we came back. the water tasted SPOILED! HAHA
