During the 1880s, people realized they could extract monocalcium phosophate from mines instead, no beef bones required.

在 1880 年代，人们意识到他们可以从矿山中提取磷酸二氢钙，而不需要牛骨头。

Like the cream of tartar reaction, when you mix monocalcium phosphate, baking soda, and water, you get carbon dioxide bubbles.

就像牙垢反应的奶油一样， 当您将磷酸二氢钙、小苏打和水混合时， 会产生二氧化碳气泡。

Enter the chemist Eben Horsford, who figured out how to make an acid called monocalcium phosphate from beef bones in 1856.

进入化学家 Eben Horsford，他在 1856 年想出了如何从牛骨中制造一种叫做磷酸二氢钙的酸。

So Horsford mixed monocalcium phosphate and sodium bicarbonate together and then added some cornstarch to help keep everything dry and prevent early reactions.

因此，Horsford 将磷酸二氢钙和碳酸氢钠混合在一起，然后加入一些玉米淀粉，以帮助保持一切干燥并防止早期反应。
