Acid Red 18 CAS#2611-82-7
Wide Range of Applications: Carmine is commonly used in various food products like fruit juices, candies, cakes, and ice cream for vibrant red coloring.
Regulated Usage: Its application is strictly controlled, with clear guidelines on usage levels to ensure food safety and prevent misuse.
High Stability: Carmine remains stable at high temperatures, with a melting point over 300°C, ensuring its reliability in diverse food formulations.
Controlled Residual Limits: It is permitted in specific food categories like red sausage casings with stringent residual limits, ensuring safe consumption.
Carmine, a natural red food coloring, is widely used in products such as fruit juice drinks, blended alcoholic beverages, carbonated drinks, candies, cakes, ice cream, yogurt, and similar foods. However, it is prohibited in dried meat, processed meats, and aquatic products. This restriction aims to prevent unethical practices where colorants might be used to conceal poor-quality or spoiled raw meats, misleading consumers about the product's freshness and safety.
According to China's Hygienic Standards for the Use of Food Additives (GB2760-1996) and related references such as ChemicalBook, the scope and maximum usage levels of carmine are aligned with those for amaranth. Carmine is also allowed in applications like candy coatings and soy milk drinks, with a maximum usage level of 0.1 g/kg. For red sausage casings, the highest permitted usage is 0.025 g/kg, and the residual limit is set at 0.01 g/kg. These regulations help ensure food safety and prevent misuse while allowing its controlled application in various food products.
