Benzene production from decarboxylation of benzoic acid in the presence of ascorbic acid and a transition-metal catalyst, Evaluation of Accelerated UV and Thermal Testing for Benzene Formation in Beverages Containing Benzoate and Ascorbic Acid, atsdr.cdc.gov/toxprofiles/tp.asp?id=40&tid=14, hpa.org.uk/webc/hpawebfile/hpaweb_c/1194947391801, Feature Preview: New Review Suspensions Mod UX, Creating new Help Center documents for Review queues: Project overview. Why don't effervescent vitamin C tablets react with the vitamin C? A pH of below 4.6 also prevents the growth of clostridia (botulism) and contributes to the flavour of fruit flavoured drinks. Also, when benzoate is combined with ascorbic acid in carbonated soft drinks, sodium benzoate forms the potent carcinogen benzene. Best approach to safely bump up version of classes. As a food additive, sodium benzoate has the E number E211. I (might) have accidentally combined these mold-killers at home: Any adverse reactions? A simplified take on how preservatives work, what they need to work, and why bother in the first place Can sodium benzoate and vitamin C interact 'badly'? Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Potassium sorbate and sodium benzoate cannot be dissolved directly in acid or fruit juice. This feature article is restricted to logged-in paid subscribers. How do I use augmented chords in my progressions? Water softening can reduce the formation of haze in clear drinks, reduce alkalinity and remove destabilising metals salts such as iron, which also encourage microbial growth and the formation of off flavours. The problem is not the benzene itself, but benzene oxide, which is formed as the body tries to get rid of benzene. However, an infrequent bottle of soda won’t hurt anyone. •Sodium benzoate (MW = 144) is a preservative. Pre-dissolved acidulant (and fruit juice) is added near the end of the process in order to partially convert the dissolved preservative salt into its less soluble free acid form. Why does the pH of soft drinks get lower as they go flat? Given one has had a glass of orange juice say, how much pop would one have to drink before a benzene molecule is formed? The use of sodium benzoate in soft drinks is often avoided in the presence of vitamin C, which can potentially convert the benzoate salt into benzene. Microbial growth in soft drinks can produce off flavours and odours, clouding and ‘inflation’ of flexible packaging from carbon dioxide released by fermentation. DMDC is very effective and is metred into the product immediately prior to filling using specialist equipment. MathJax reference. Asking for help, clarification, or responding to other answers.

A combination of raw material quality controls (including water treatment) and heating (eg flash pasteurisation of fruit syrups) in conjunction with strict GMP and plant cleanliness contributes to a low initial bio burden in raw materials.
