The black mold behind soda's citrus tang

HERE’S THE INTERESTING PART

That refreshing, citrusy tang in your favorite soft drink does not come from a pristine lemon grove. It is mass-produced by feeding sugar to Aspergillus niger, a black mold that naturally synthesizes citric acid as a byproduct of its digestion. Your crisp, refreshing beverage is essentially flavored by industrial fungal sweat.
