What is allura red?

Allura red is a synthetic dye made from petroleum. It belongs to the azo dyes, which form a large group of dyes that contain an azo bridge (-N=N-). Allura red has the molecular formula C18H14N2O8S2 and the CAS number 25956-17-6. It is also known under the names FD&C Red 40, Food Red 17 or C.I. 16035.

Allura red is a dark red, water-soluble solid that turns orange in acidic solution. It is heat-resistant and lightfast, but not oxidation-stable. It can be mixed with other colorants to create different shades.

What are the advantages of Allura Red?

The main benefit of Allura Red is its ability to add attractive color to dog food. Many dogs are attracted to colorful foods and prefer to eat them over bland or gray foods. This can improve acceptance and food intake, which can be especially important for picky or sick dogs.

Another advantage of Allura Red is its low toxicity. According to the European Food Safety Authority (EFSA), the Acceptable Daily Intake (ADI) for Allura Red is 7 mg/kg body weight per day. This means that a 10 kg dog could ingest up to 70 mg of allura red per day without suffering any adverse health effects. The EFSA has also determined that Allura Red has no carcinogenic, mutagenic or reprotoxic effects.

What are the disadvantages of Allura Red?

The main disadvantage of Allura Red is its potential allergenic effect. Some dogs may be sensitive to Allura Red and show symptoms such as skin rash, itching, breathing difficulties or gastrointestinal problems. These reactions can vary from mild to severe and may require veterinary treatment.

Another disadvantage of Allura Red is its possible influence on the behavior of dogs. Some studies have shown that Allura Red and other azo dyes can affect activity and attention in children. Although there is no direct evidence that this is also the case in dogs, it could be that allura red alters the behavior of dogs and makes them more restless or aggressive.
