Hi guys, I could really use some help to how produce chocolate syrup with preservative. Currently I produce fruit syrup using food acid (330) and sodium benzoate, but with chocolate its don't work.
After a few days the chocolate syrup starts to ferment and the bottle is full of gas.
Somebody have any idea how I resolve this problem?
The recipe of my chocolate syrup is water and sugar (1/1), cocoa powder and preservative (food acid 330 and sodium benzoate)
