When exposed to an acidic environment, garlic, which is typically creamy white, can turn blue or green. If garlic is exposed to any acidic component, such as lemon juice or vinegar, for an extended period, it may turn blue or green.
The molecules in garlic cloves are rearranged as a result of the acidity. As a result, polypyrroles are produced, which are the chemicals that provide green or blue color to garlic cloves. Not always, this response happens right away. It may take several hours for it to happen. Although whole cloves of garlic can change color, smaller bits of garlic are more likely to do so.

Even for some traditional Chinese cuisines, blue garlic is in high demand. Among other things, Laba suan is a vinegar-greened garlic condiment. During the Chinese New Year, people consume garlic cloves that are jade in color.
One can just blanch the garlic cloves before fermenting them to avoid the color turning blue. However, some of the flavor will be gone. It is best to simply get used to the strange color and savor the garlic in all its splendor.

Simple Strategies to Avoid Blue or Green Garlic

Garlic Should Be Boiled Before Use

It is best to blanch garlic in advance to avoid it becoming blue or green. Before immersing the garlic in freezing water, dip it in boiling water for 15 seconds. Lowering the sulfur and alliin components will aid in preventing discoloration. Thinly sliced garlic can be quickly toasted in oil, and the resulting garlic oil is delicious and addicting. Garlic is less likely to react to things like vinegar or tap water that is mineral-rich if it has been cooked prior.
However, you can also blanch whole garlic cloves before pickling if you intend to use this garlic for anything like pickles. Simply put your garlic cloves in boiling water or boil them for about 15 seconds, then remove them and plunge them into freezing water to stop the cooking process. Use this with caution as doing so may potentially result in flavor loss!

Creating garlic powder

Garlic discoloration can be completely avoided by powdering or granulating fresh garlic cloves. Why does garlic turn blue? They won’t undergo any chemical reactions and won’t turn blue or green because they have a lesser chemical property. Garlic powder does not contain any alliin, hence it will not at all become blue or green when exposed to acid.
Consider making garlic powder out of them if utilizing raw garlic would be too troublesome. It will swiftly dissolve in your meals and does not include any alliin chemicals that could cause a reaction. Another well-liked alternative is garlic granules. But bear in mind that the flavor won’t be quite as potent as using actual garlic. This is preferable for people who don’t use garlic frequently or don’t like the flavor of it. If you are unable to manufacture your garlic powder, you can also purchase it. But fresher spices are produced when garlic powder is made from scratch. For instance, ground coriander is frequently done at home.

Use less of certain metals

Aluminum, brass, and copper should not be used for preparing garlic. Use wood or stainless steel instead, as these won’t cause the garlic to become blue or green. Instead, use stainless steel while preparing garlic. It is a garlic lover’s best friend because it has no copper and is available practically everywhere.

Utilize freeze-dried onion powder

Garlic can avoid turning green by being covered with freeze-dried onion powder, according to research. The enzymes in the onions react, preventing the garlic from turning any shade of brown. Garlic bulbs were able to persist longer without losing their color thanks to the additional component. It appears that when onions are exposed to garlic, their tear-jerking enzymes react by preventing the development of pigments. Whether raw onions or normal onion powder will have the same impact is unknown. The main drawback is that freeze-dried onion powder could be hard to locate in conventional stores.

Conclusion

Why does garlic turn blue ? The phenomenon of garlic turning blue is an odd and unharmful event caused by chemical reactions involving sulfur compounds in garlic and some outside variables like copper and acids. It’s crucial to note that, despite the color change in the garlic possibly being unexpected, neither the garlic’s safety nor flavor has been compromised. Why does garlic turn blue ? The blue-tinged transformation of garlic serves as a reminder of the intricate chemical makeup of this multipurpose culinary ingredient. Garlic can develop blue or green pigments when in contact with copper or acidic materials, which can be rather showy while cooking.
