Phosphoric acid is often used today to prolong the shelf life of alcoholic beverages.

酸现在常被用来延长酒精饮料保质期。

The residues were indeed high in phosphoric acid, a product of barley grains added during the fermentation process.

这些残留物中确实含有大酸，酸是在发酵过程中添加大麦颗粒产物。

So how does the body respond to such a large amount of phosphoric acid when you drink a can of Coke.

" The use of hops was unknown to the ancient Egyptians, and we think that they used phosphoric acid to preserve their beer."

“古埃及人不知道啤酒花用途，我们认为他们用酸来保存啤酒。”

Phosphate ion has a three charge, so it bonds with three hydrogen ions to form phosphoric acid.

酸根离子带有三个电荷， 因此它与三个氢离子结形成酸。

Because there's still phosphoric acid in a lot of sodas, but that carbonic acid also gives it that extra crispness.

因为许多汽水中仍然含有酸，但碳酸也赋予了它们额外清爽感。

But thanks to the lack of sugar and phosphoric acid plus all those extra minerals in there it was also a hundred times better than soft drinks.

但多亏了其中缺乏糖和酸，加上其中所有额外矿物质，它也比软性饮料好一百倍。

Phosphoric acid via barley would have made it possible to mass produce beer, store it for extended periods, and even transport it—all consistent with the important role beer played in ancient Egyptian society.

酸通过大麦使得大规模生产啤酒成为可能，还能长时间储存， 并且甚至可以运输——这一切都与啤酒在古埃及社会中扮演重要角色相吻。

" The use of hops was unknown to the ancient Egyptians, and we think that they used phosphoric acid to preserve their beer." The residues were indeed high in phosphoric acid, a product of barley grains added during the fermentation process.

" 古代埃及人不知道使用啤酒花，我们认为他们使用酸来保存啤酒" 。 这些残渣确实含有大酸，这是在发酵过程中添加大麦粒产物。
