Which additive is known as yellow dye #5?

The additive known as yellow dye #5 is tartrazine. This synthetic dye is commonly used in food products, beverages, and medications to impart a bright yellow color. It is particularly popular due to its appealing hue and versatility in various applications.

Tartrazine is recognized as food additive E102 in Europe and is often subjected to regulatory reviews to ensure its safety for consumption. Its use can be found in a range of products, from candies and snacks to drinks, making it one of the more widely known colorants in the food industry.

Other options, while they may relate to additives, do not specifically refer to yellow dye #5. For example, monosodium glutamate (MSG) is primarily used as a flavor enhancer, sulfites serve as preservatives, and the term "coloring agent" is a broad category that encompasses numerous substances, but does not identify a specific colorant like tartrazine does. Understanding these distinctions provides clarity on the role of various food additives, particularly in the context of color enhancement.
