Say

It's like it's gone bad.

So, today

In order to make everyone feel safe to eat garlic

I'll tell you

How did Laba garlic become “green”?

It turns out that garlic turns green because a chemical reaction occurs during the pickling process, producing green pigment.

Garlic contains some sulfur compounds, amino acids and organic acids, which are originally colorless, but they will react in an acidic environment to produce yellow and blue pigments, which will appear green when superimposed on each other.

The blue pigment is more active and will decompose if exposed to high temperature or strong light, leaving only the yellow pigment. So sometimes, we will find that Laba garlic will turn yellow.

Therefore, it is recommended that when pickling Laba garlic, you should place it in a place with relatively low temperature and not easily exposed to light.

In addition, Laba garlic is not suitable for everyone. People with poor stomach and digestion should try to eat less.
