春節(jié)假期接近尾聲，回家過(guò)年的你是否在親友團(tuán)聚的餐桌上喝了不少飲料？

“隔夜飲料”，一直是不少網(wǎng)友關(guān)心的話題。

Beverages are a staple of festive gatherings with family and friends. Whether it's safe to drink leftover beverages from the night before has long been a topic of discussion online.

“千萬(wàn)不要喝隔夜飲料”話題下，不少網(wǎng)友現(xiàn)身說(shuō)法：

當(dāng)然，也有網(wǎng)友發(fā)出疑問(wèn)：

所以，隔夜飲料究竟能不能喝？開(kāi)蓋后的飲料，飲用最佳時(shí)間是多久呢？

答案是：不止隔夜飲料，開(kāi)封后超過(guò)12小時(shí)的飲料，都不建議繼續(xù)飲用！

Is it safe to drink beverages left out overnight? And how long do opened drinks actually last? The rule of thumb is that once a beverage has been opened, it's best to consume it within 12 hours, overnight or not.

飲料的瓶蓋一旦被擰開(kāi)，就意味著這些口感各異的液體所處的無(wú)菌環(huán)境被破壞了。特別是室溫存放，更容易導(dǎo)致細(xì)菌繁殖。

中國(guó)農(nóng)業(yè)大學(xué)食品科學(xué)與營(yíng)養(yǎng)工程學(xué)院副教授吳曉蒙建議：開(kāi)瓶后沒(méi)有喝完的飲料，最好是密封冷藏保存，而且要盡快喝完！一般情況下，飲用時(shí)間不得超過(guò)12小時(shí)！

此外，相比倒出來(lái)喝飲料，對(duì)嘴喝飲料的微生物污染概率更高！不同飲用方式給飲料帶來(lái)的微生物污染風(fēng)險(xiǎn)也不同。

試驗(yàn)測(cè)試發(fā)現(xiàn)，直接對(duì)嘴喝的飲料，51%的樣本被檢出瓶中剩余飲料里有微生物生長(zhǎng)，主要是口腔微生物群（比如鏈球菌和葡萄球菌）；而倒出來(lái)喝的飲料，只有18%的樣本被檢出剩余飲料中有微生物生長(zhǎng)，主要是環(huán)境微生物（比如霉菌）。

此外，試驗(yàn)還發(fā)現(xiàn)用嘴接觸瓶口的方式造成的飲料被污染程度也有差別。相比于用嘴含住整個(gè)瓶口，只用嘴接觸一半瓶口的喝法，污染到瓶里的細(xì)菌相對(duì)較少。

The experiment also showed that the way a person drinks from a bottle can influence contamination levels. Drinking with only the lips touching half of the bottle opening introduced fewer bacteria into the liquid compared to drinking with the mouth wrapped fully around the rim.

這時(shí)候，有好奇網(wǎng)友發(fā)問(wèn)：那我不對(duì)嘴喝，倒一半在杯子里，剩一半放冰箱下次喝呢？

吳曉蒙副教授分析說(shuō)，飲料在包裝未開(kāi)封前屬于密封狀態(tài)，開(kāi)蓋和飲用后很容易接觸到嘴里或者空氣中的細(xì)菌、真菌等微生物。在后續(xù)存放過(guò)程中，只要有合適的外界條件（溫度和濕度）和適當(dāng)?shù)酿B(yǎng)分，這些微生物就會(huì)迅速繁殖！

Expert explained that beverages are sealed and remain sterile until opened. Once the package is opened and consumed, the drink is easily exposed to bacteria, fungi, and other microorganisms from the mouth or surrounding air. If conditions such as temperature, humidity, and nutrient levels are favorable, these microbes can multiply rapidly during storage.

雖然預(yù)包裝飲品開(kāi)蓋后，在室溫下放置2個(gè)小時(shí)后再飲用，不會(huì)引起太大的問(wèn)題，但并不建議大家這樣做，如果大量飲用，可能會(huì)帶來(lái)危害。一些鮮榨果汁、現(xiàn)做奶茶類飲料以及蛋白質(zhì)含量較高的飲料，建議要一次性喝完。

節(jié)儉是美德，但開(kāi)封后的飲料真的不適合留著慢慢喝。

如果一定要喝，記住以下3點(diǎn)：

① 盡量將飲料倒入干凈的杯子中飲用，尤其大瓶飲料，不要對(duì)瓶吹。

Try to pour the beverage into a clean cup for drinking, especially with large bottles—avoid drinking directly from them.

② 對(duì)嘴喝過(guò)的飲料，最好在1~2小時(shí)內(nèi)喝完，尤其是現(xiàn)做的奶茶，更要1小時(shí)以內(nèi)，原料越復(fù)雜越要盡快喝完。

For beverages that have been sipped directly from the container, it is best to finish them within 1–2 hours, especially freshly made milk tea, which should be consumed within an hour. The more complex the ingredients, the quicker it should be finished.

③ 實(shí)在沒(méi)法兒立即喝完的飲料，密封冷藏好，但冷藏時(shí)間最好不要超過(guò)12小時(shí)（畢竟冷藏只能減緩微生物生長(zhǎng)，不能完全阻止）。

If you really can't finish it immediately, seal it tightly and refrigerate it, but you'd better not keep it refrigerated for more than 12 hours (since refrigeration only slows microbial growth and does not completely prevent it).

你家的冰箱里還有沒(méi)有喝剩的飲料？如果有，一定要抓緊處理掉哦。
