Pickled garlic is a popular condiment often paired with dishes like noodles and vermicelli, and is also used in various dipping sauces. It not only enhances flavors but also offers several health benefits. However, sometimes pickled garlic turns green, which can be concerning for consumers. So, what causes this color change, and is it safe to consume?
Why Does Pickled Garlic Turn Green?
The green color of pickled garlic is a result of a natural chemical reaction between the compounds in garlic and acetic acid in vinegar. This is a normal occurrence and does not indicate spoilage or unsafe product. The green hue is caused by the reaction between the natural sulfur in garlic and traces of metals such as copper, iron, or other compounds in the vinegar that induce a green color.
Therefore, even if your pickled garlic turns green, it is still safe to eat. To avoid this discoloration, you can try reducing the amount of vinegar used or opt for a higher-quality vinegar for pickling.
