The food additive brilliant or sparkling black , also known by its industrial and scientific title E151 is tetrasodium salt, used as a colorant in many food products in the European Union, including Bulgaria.
Fully synthetic product from the group of nitrogen compounds (nitrogen-containing), the molecule of E151 is stabilized by two aryl groups, which makes the black dye compatible for use with other dyes such as orange E110, yellow E104 and E102 and red E122 and E123 to achieve a palette from brownish, green and some other bright, brilliant colors and shades.
It is most often used for coloring decorative elements, syrups , glazes and additives in the factory production of desserts , cakes , ice cream , mustard , semi-finished soups , pasta , soft drinks , flavored milk drinks , caviar and some semi-finished products .
Used in the food industry since the early 70s of last century, a number of studies (from 1975, 1978 and 1981) confirm its safety for the population. According to a 2010 study by the European Food Safety Authority ( EFSA ), E151 does not cause adverse health effects if the daily dose of 1 milligram per kilogram of body weight is not exceeded. Within these limits, the supplement does not cause carcinogenic, toxic or metabolic damage to the human body.
The latest EFSA study confirms that the supplement has the potential to cause or exacerbate allergic reactions , especially in people suffering from intolerance to salts or salicylic acid esters . This makes products containing E151 highly not recommended for people experiencing side effects and allergic reactions to aspirin ( acetylsalicylic acid ).
It is recommended to avoid products containing the supplement and by people suffering from seasonal allergies , asthma with an allergic component, chronic rhinitis and skin rashes . This is due to the possible biochemical interaction of E151 with components of the immune system, leading to the release of histamine - an organo-nitrogen compound with a key role in immunological reactions, inflammatory processes and allergies.
Evidence is available that the processing of E151 by intestinal bacteria may also lead to the release of certain toxins and carcinogens, but further, in-depth and definitive research is needed.
For the past 15 years, the compound has been banned for use in the United States, Belgium, Denmark, France, Germany, Sweden, Austria, Switzerland, Japan, but is still allowed in other EU member states and some Central and South Asian countries. America.
