Acid Red 18 CAS#2611-82-7

1.Broad Applicability: As a bright red pigment, carmine is extensively incorporated into numerous food items including fruit juices, confectionery, baked pastries and ice cream.

2.Controlled Dosing Rules: Authorities impose rigorous restrictions on its administration, alongside explicit dosage standards to safeguard food safety and avoid improper overuse.

3.Superior Thermal Stability: Carmine boasts excellent heat resistance with a melting point exceeding 300°C, maintaining consistent performance when added to all types of food formulas.

4.Specified Residue Thresholds: The pigment is approved for select food products such as red sausage casings, subject to strict residue caps that guarantee safe edible intake.

Product Details

Carmine, a naturally sourced red pigment for food, enjoys extensive application across an array of edible goods, including fruit juice beverages, compound wine drinks, carbonated sodas, confectionery, pastries, ice cream and yoghurt. Nevertheless, its addition is banned for dried meat, processed meat items and aquatic food products. Such regulatory limits are enacted to curb improper industrial conduct—specifically, stopping manufacturers from masking deteriorated or low-grade raw meat with color additives, which would otherwise mislead buyers regarding the freshness and safety of food items.

Per China’s Hygienic Standards for the Application of Food Additives (GB2760-1996) and supporting data resources including ChemicalBook, carmine shares identical permitted application ranges and maximum dosage thresholds with amaranth. The pigment can also be incorporated into candy outer coatings and soymilk beverages, capped at a maximum addition amount of 0.1 grams per kilogram. For red sausage casings, the legal upper usage limit stands at 0.025 g/kg, alongside a residual concentration ceiling of 0.01 g/kg. Such regulatory specifications enable standardized, safe deployment of carmine in diverse food categories while eliminating improper overuse of the colorant.
