I'm developing a fruit juice for humans, I just want a second opinion about allowed food preservatives. Does anyone happen to know if there are any chemical preservatives that can extend the shelf life of fruit juice better than sodium benzoate?

**Allowed** is crucial here and it might strongly depend of where the product is to be sold. You might want to have a look at national legislations.


* For Germany, the [Zusatzstoff-Zulassungsverordnung](https://www.gesetze-im-internet.de/bundesrecht/zzulv_1998/gesamt.pdf) lists allowed preservatives and their maximum concentrations in different products.
* For Canada, *Health Canada* provides a [List of Permitted Preservatives](http://www.hc-sc.gc.ca/fn-an/securit/addit/list/11-preserv-conserv-eng.php).
