'''Sodium dehydroacetate''' is a [[Compound (chemistry)|compound]] with the formula Na(CH₃C₅HO(O₂)(CH₃)CO). It is the [[sodium]] [[salt (chemistry)|salt]] of [[dehydroacetic acid]]. It is used as a preservative in food,<ref>{{cite journal |doi=10.1016/j.postharvbio.2019.01.006 |title=Combination of sodium dehydroacetate and sodium silicate reduces sour rot of citrus fruit |date=2019 |last1=Li |first1=Lu |last2=Tang |first2=Xu |last3=Ouyang |first3=Qiuli |last4=Tao |first4=Nengguo |journal=Postharvest Biology and Technology |volume=151 |pages=19–25 }}</ref> cosmetics and personal care products such as shower gels, which is highly effective against a broad range of bacteria even at low concentrations such as 0.075 g/kg in meat. Its use is regulated in China, Japan and the USA, thus it can only be used in certain foods such as picked vegetables, fermented soy, compound seasonings and pickled mushrooms in China, and only peeled pumpkins in the US at 65 parts per million. It is not approved for use in the EU. It adds an acetic odor to food which can be mitigated using flavorings.<ref>{{Cite web|url=https://www.zmuni.com/en/news/food-additives-gradually-going-down-the-drain-sodium-dehydroacetate-e-266/|title=Food Additives Gradually Going Down the Drain: Sodium Dehydroacetate (E 266)|date=November 30, 2022|website=ZMUni Compliance Centre}}</ref> It can also be used in bread and pastries.<ref>{{Cite web|url=https://foodadditives.net/preservatives/sodium-dehydroacetate/|title=What is Sodium Dehydroacetate in food: Uses and Safety|first=James|last=Han|date=July 20, 2020|website=foodadditives.net}}</ref> It is highly effective when applied to oranges.<ref>{{cite journal |last1=Li |first1=Lu |last2=Tang |first2=Xu |last3=Ouyang |first3=Qiuli |last4=Tao |first4=Nengguo |title=Combination of sodium dehydroacetate and sodium silicate reduces sour rot of citrus fruit |journal=Postharvest Biology and Technology |date=May 2019 |volume=151 |pages=19–25 |doi=10.1016/j.postharvbio.2019.01.006 }}</ref>
