喝過期半年的汽水 還有救嗎?

Aspartame in diet sodas will naturally break downover time, especially if stored in highertemperatures, and in both diet and regular sodas thecarbon dioxide will produce further carbonic acid(incidentally making itself flat), but aside from achange in flavour, the beverage is likely to becompletely safe to drink -- and will probably stilltaste good.

汽水中的天冬甜素會隨著時(shí)間自然削弱，尤其是被儲存在高溫條件下的時(shí)候，無論是飲用汽水還是普通蘇打水中，二氧化碳都會產(chǎn)生更多的碳酸(可能會使它變癟)，但是除了味道上有所變化，飲料還是完全可以放心飲用的-而且味道可能依然很好。

It would take a very, very long time for the flavour to be affected enough to be completelyunacceptable -- and even then it would still be safe.

讓味道變得完全不可接受需要很長，很長的時(shí)間-但即使到那時(shí)汽水還是可以被放心飲用的。

Even if all of the remaining carbon dioxide has broken down into sour acid (which would takeyears in an unopened can), it's still far more dilute and less acidic than your stomach acid, assuming you can handle the terrible flavour.

就算所有剩下的二氧化碳都弱化成酸(在沒打開的罐子里應(yīng)該需要好幾年的時(shí)間)，和你的胃酸相比它還是更淡的，沒有那么酸，只要你能忍受它糟糕的味道的話。

Soda is usually consumed well before this becomes a problem, of course.

當(dāng)然，在這成為一個(gè)問題之前，汽水一般已經(jīng)被賣得差不多了。

 

 

One caution should be made: any sodas that contain real fruit juice, like orange soda, grapesoda, etc., should be viewed as potentially unsafe after their expiration. They can mould orferment rapidly once the container is opened, in the case of aluminum cans, and glass orplastic bottles which have less perfect seals should be viewed as unsafe even before opening.

值得注意的是：任何含有純果汁的碳酸飲料，比如橙子味汽水、葡萄味汽水等等，過期之后都被認(rèn)為是無法安全飲用的。一旦密閉容器被打開，它們可能會很快地發(fā)霉或者發(fā)酵，鋁罐、玻璃或者塑料罐都可能密封得沒有那么好，甚至往往在被打開之前就是不安全的。

PS: The date on the packaging is the "Optimum Taste Date." This is the date by whichcompanies recommend you to consume the beverage in order to enjoy the optimum taste.

另：包裝上的日期是“最佳飲用期”。這是食品公司的建議，為了品嘗到最佳的味道，最好在這個(gè)日期之前喝完飲料。
