The Cause of Green Pickled Garlic is mainly due to chemical changes that occur during the pickling process. When dry garlic is placed in vinegar, the acidic environment breaks down the garlic’s cell walls. This damage allows amino acids and sulfur compounds naturally present in garlic to mix. As a result, the process releases isoalline, which then reacts with the amino acids to form blue-green pigments called anthocyanins. These pigments naturally exist in garlic, but their amount increases significantly during this chemical reaction, causing the green color.
Moreover, the green color can also result from reactions between the sulfur compounds in garlic and metals like copper, which may be present in the water or utensils used for pickling. For example, when garlic comes into contact with copper, the reaction forms copper sulfate, giving the garlic a blue-green hue. The use of cast iron, aluminum, or copper containers during pickling also contributes to this color change. Understanding these causes helps in controlling the process to maintain the desired appearance and quality of pickled garlic.
