We didn't do anything radical, but we'd add some contrast and a little bit of saturation.

我们没动任何大手脚，但我们增加了一些对比度和一点点饱和度。

Fermentation can take place without the presence of extracted nutritive liquor, but proceed vacuum deoxygenation and add carbon dioxide to saturation and packed into final product.

浸提得到的营养液也可不参与发酵，而进行真空脱氧，加纯净二氧化碳饱和处理，即可包装得到成品。
