Ponceau (17th century French for "poppy-coloured") is the generic name for a family of azo dyes. Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons; it is stable to light, heat, and acid but fades in the presence of ascorbic acid.

胭脂红，又名食用赤色102号（日本）、食用红色7号、丽春红4R、大红、亮猩红，为水溶液偶氮类着色剂，其化学名称为1-（4'-磺酸基-1'-萘偶氮）-2-萘酚-6,8-二磺酸三钠盐，是苋菜红的异构体，分子式为C20H11O10N2S3Na3。

Ponceau 4R consists essentially of trisodium 2-hydroxy-1- (4-sulfonato-1-naphthylazo) naphthalene-6,8-disulfonate and subsidiary colouring matters together with sodium chloride and/or sodium sulphate as the principal uncoloured components.

Ponceau 4R (which is known by more than 100 synonyms including C.I. Food Red 7, Cochineal Red A, and New Coccine) is a synthetic red azo dye used in a range of alcoholic and nonalcoholic beverages, and a variety of foodstuffs including confectionary, desserts, cheeses, meats, preserved fruits, and sauces.

Ponceau 4R (E 124) is an azo dye allowed as a food additive in the EU that has been previously evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 1983 and the EU Scientific Committee for Food (SCF) in 1984. Both committees established an Acceptable Daily Intake (ADI) of 0-4 mg/kg body weight (bw)/day.

At the maximum concentration of ponceau 4R used in fishing baits (15 mg/kg complementary feed), the PEC sw does not exceed the threshold value of 0.1 μg/L for aquaculture from land‐based fish farms. Thus, the assessment stops in Phase I of the FEEDAP guidance on the safety of the additive for the environment (EFSA FEEDAP Panel, 2019).

Ponceau 4R is a monoaze dye that occurs as reddish powder or granules. It is principally the trisodium salt of 2-hydroxy-1- (4-sulfonato-1- naphthylazo)-6,8-naphthalenedisulfonate and subsidiary coloring matters, together with sodium chloride and/or sodium sulfate as the principal uncolored components.

Ponceau 4R is a synthetic red azo dye commonly used in the food industry to add or enhance color in various products. It serves the following functions: Colorant: Ponceau 4R imparts a bright red hue to a variety of food and beverage products. It is often used in candies, soft drinks, jams, processed meats, baked goods, and snack foods.

Ponceau 4R is a sulfonated azo dye, used as a food colorant to give red color to different food products, such as alcoholic beverages, soft drinks, bakery products, candies, syrups, preserved fruits, etc. An acceptable daily intake (ADI) of 0.4 to 0.7 mg (kg body weight) -1 was set for Ponceau 4R by the European Food Safety Authority (EFSA) in ...
