01Origin
Where it comes from
Urea, a simple nitrogen compound (also a normal human metabolite), synthesized industrially.
02Usage
How it's used
Used in chewing gum, where it raises pH and modifies saliva and flavour; also a yeast nutrient / fermentation aid in some winemaking.
03Safety
Safety profile
No ADI specified; urea is a normal body metabolite, and food-use levels are low.
04Properties
