Định Nghĩa và Ý Nghĩa của "color retention agent"

What is a "color retention agent"?

A color retention agent is a food additive used to help maintain the color of food products over time by preventing or delaying color changes caused by exposure to light, air, heat, or other factors, especially during storage, transportation, and shelf life. These agents work by stabilizing pigments or preventing oxidation reactions that can lead to discoloration or fading. They are often added to products such as fruit juices, canned fruits and vegetables, cured meats, bakery items, and processed snacks. Common color retention agents include antioxidants, sulfites, and specific enzymes that inhibit enzymatic browning. Color retention agents are regulated by food authorities to ensure they are safe for consumption and used within recommended levels.
