Copper chlorophyll extract, also known as copper chlorophyllin, is a derivative of chlorophyll that has been chemically modified by replacing the central magnesium ion with copper. This modification enhances its stability and allows it to be used as a food coloring agent. Copper chlorophyll extract provides a vibrant green color to food and beverage products, similar to chlorophyll extract. It is commonly used in various food items, including candies, chewing gums, and beverages, to add an appealing green hue. Like chlorophyll extract, copper chlorophyll extract is generally considered safe for consumption and may also offer antioxidant properties. However, it's important to note that excessive consumption should be avoided, and individuals with specific dietary restrictions or health conditions should consult a healthcare professional.
