Food Additives in
Soft Drinks & Beverages
Soft drinks and flavoured beverages use food additives primarily for preservation, colour, flavour stabilisation, and sweetening. Preservatives like sodium benzoate (E211) and potassium sorbate (E202) inhibit microbial growth. Acidity regulators like citric acid (E330) and phosphoric acid (E338) provide tartness and lower pH for preservation. Artificial colours — particularly caramel colour (E150a–E150d) in cola drinks and synthetic dyes in fruit-flavoured drinks — are widely used. The sodium benzoate-ascorbic acid reaction to form trace benzene prompted regulatory reviews in multiple jurisdictions.

Can sodium benzoate (E211) in soft drinks form benzene?
Yes — sodium benzoate and ascorbic acid (vitamin C) can react to form trace amounts of benzene, a known human carcinogen, when both are present in a drink exposed to heat or light. This reaction was identified by FDA researchers in the 1990s and investigated more broadly in the 2000s. Surveys found benzene above WHO drinking water guidelines in some products. Manufacturers reformulated many products; ongoing monitoring shows most currently available drinks have benzene levels below 5 ppb. Regulatory agencies consider current exposure levels acceptable but continue monitoring.
Is caramel colour (E150c) in cola drinks carcinogenic?
Caramel colour III (E150c, ammonia caramel) and IV (E150d, ammonia-sulfite caramel) contain 4-methylimidazole (4-MEI) as a trace impurity from the manufacturing process. IARC classified 4-MEI as "possibly carcinogenic to humans" based on animal studies. The state of California added it to Prop 65 lists, requiring warning labels above 29 μg/day exposure. EFSA and FDA reviewed the evidence and did not find grounds for regulatory action, noting animal study doses far exceeded realistic human dietary exposure from caramel colour consumption. Several manufacturers have voluntarily reduced 4-MEI levels.
Why do sports drinks contain so many E numbers?
Sports drinks are designed to replace electrolytes, provide rapid energy, and maintain palatability under exercise conditions. They typically contain acidity regulators (citric acid, E330), sweeteners (sucrose, glucose, or intense sweeteners), electrolytes in salt forms (sodium citrate E331, potassium chloride), and often synthetic colours for product differentiation. The electrolyte salts are added for physiological function rather than as food additives per se, but they carry E numbers because the same compounds are regulated under food additive law.
