What pollute as water natural resources is increasingly serious, increasing person begins to use bottled mineral water or bucket outfit mineral water serves as drinking water, but we can see bottle body is writing mineral water to have the expiration period normally, is this how to return a responsibility? Still do not have the expiration period hard into water?
What is we analyse the expiration period first, so called expiration period, the water inside the time limit that sets in this namely won't produce metamorphism, is that what brought about metamorphism?
As a result of,the putrefaction of food basically is microbial, oxidation, rodent, temperature, enzymatic kind, helminth of moisture, insect and illumination cause, and besides microbial besides, other factor won't constitute menace to mineral water. But, the mineral water that accords with national level is microbial content very little, also furnish without enough nutrient in mineral water live multiply.
So mineral water does not have the expiration period, clean mineral water can put on 500 years not to deteriorate, can degenerative is the container that packs mineral water.
The plastic bottle that holds mineral water is met after passing period of time soak chemistry material, although these are chemical material is not certain and harmful, but the flavour of mineral water can produce change. And, plastic bottle can appear after experiencing period of time ageing, wear away, at that time, the circumstance that once bottle appears,damages, microbial can breed in great quantities, cause metamorphism of mineral water happening.
Should check body to whether have damaged when we buy mineral water among daily life so, reserve requirement is good, whether be and examine mineral water inside the expiration period.
