Sodium benzoate

Sodium benzoate is a preservative.It is also used in fireworks as a fuel in whistle mix, a powder that emits a whistling noise when compressed into a tube and ignited.It does have its downsides: there is a high danger of explosion when the fuel is sharply compressed because of the fuel's sensitivity to impact.The mechanism starts with the absorption of benzoic acid into the cell.
Professor Jim Stevenson from Southampton University, and author of the report, said: "This has been a major study investigating an important area of research. We know that many other influences are at work but this at least is one a child can avoid."On 10 April 2008, the Foods Standard Agency called for a voluntary removal of the colours (but not sodium benzoate) by 2009.In addition, it recommended that there should be action to phase them out in food and drink in the European Union (EU) over a specified period.
Benzoic acid and called benzoin acid, sodium benzoate and says it benzoin acid sodium. In ordinary temperature benzoic acid soluble in water, in the air in the volatile, hygroscopicity. Benzoic acid often in free acid, ester derivatives thereof or forms exist widely in nature. Use phthalic anhydride decarboxylation obtained by the final product is not easy to refined, and high production costs, not only in batch of pharmaceutical products used in the process of manufacturing. Toluene LvHuaFa products is not suitable for application in food additives.
Benzoic acid in acid conditions solubility is low, if not stir evenly, there will be local have benzoic acid crystallization precipitation. Add food preservatives goal is to improve food quality and prolong conservancy period, convenient processing and preservation nutrients. As food science workers facing the public to the food safety unprecedented attention or enterprise fruitive pressure, should adhere to the scientific attitude is responsible for the argument, not imaginary food preservatives, optional misinterpretation.
