Product Description

Among the azo food dyes, Allura red AC, Azorubine, Brilliant Blue FCF, Sunset Yellow FCF and Tartrazine are the most commonly found in edible goods. Due to restricted functionality and/or regulatory requirements, the use of other azo dyes such as Amaranth, Citrus Red 2, Litholrubine BK, Ponceau 4R, and Orange B have been limited to specific applications (see Table 1). For example, Citrus Red 2 is only applied to enhance the external appearance of fresh oranges. Among the triarylmethane dyes, Fast Green FCF is the least used, since similar hues can be obtained using a combination of other colors. The extensive use of the only xanthene compound approved in the US and the EU, erythrosine, has progressively decreased in recent years due to its lower stability in comparison to other available red synthetic food dyes and health concerns associated with its use.

While several natural color additives, such as riboflavin and anthocyanins, contribute the food with desirable functional properties, e.g., antioxidant and bacteriostatic activity, or potential health benefits, synthetic colors do not exhibit any nutritional value or health attribute. Most of them are poorly absorbed in the intestine, and their consumption has been potentially associated with adverse health effects, such as allergenicity and behavioral disorders in children. Additionally, azo and triarylmethane color compounds can electrostatically interact with proteins, which might reduce protein functionality in foods and in the body.

Despite their lack of nutritional value, these colors are gaining popularity as stains, markers or intrinsic sensors. Their comparative innocuity makes them adequate replacements of toxic dyes in diagnostic and analytical tools, such as Fast Green FCF as a safe stain for tumor detection, azo dyes as low-cost tracing dyes for the analysis of nucleic acids and proteins, and Allura Red AC as an effective scatterer in luminescence spectroscopy. Additionally, the environmental sensitivity of the photophysical properties, i.e., luminescence intensity, quantum yield and lifetime, of approved food azo dyes and triarylmethane compounds have been recently reported, and their potential application as intrinsic sensors of food quality attributes, e.g., micro and bulk viscosity of liquid and semi-solid foods has been described. Similarly, the use of xanthene dyes as sensors of molecular mobility, dynamic heterogeneity, and air permeability has been extensively explored and used in food model systems to evaluate and characterize them.
