First of all, it should be known what sodium benzoate is.
Sodium benzoate (chemical formula: C6H5CO2Na), E number zhiE211, is the sodium salt zhuan of benzoic acid. Sodium benzoate is a very commonly used food preservative, which has the effect of preventing deterioration and acidification and prolonging the shelf life, and is widely used in countries around the world. However, concerns about its toxicity in recent years have limited its use, and some countries such as Japan have stopped producing sodium benzoate and restricted its use.
It is already known that it is a preservative, and it is added to the old vinegar to prevent the aging vinegar from deteriorating.
However, the national new old vinegar standard does not allow the addition of preservatives. Moreover, vinegar that has reached a certain acidity does not require the addition of preservatives. The old vinegar is generally brewed for a long time and the acidity is high enough that there is no need to add preservatives. Therefore, for their own health, this kind of old vinegar with preservatives added, or do not buy it!
