Is it okay to consume blue pickled garlic?

Blue garlic might not look appealing, but it’s completely safe to eat and tastes good.

Kindly notice that there is no much scientific backing for the concept of their being safe. It is all that normally people share.

Enzyme Reactions: Finding the Culprit

The color change in garlic is caused by enzyme reactions. Garlic has enzymes like alliinase that, when combined with other compounds, create colored pigments.

In simpler terms, the enzymes in garlic can break down sulfur compounds into a type of acid. When this acid encounters tiny amounts of metals, it turns into a blue or green color.

Why are my pickles changing to a blue hue?
