Answer 2

citric acid, is also a preservative, but its most common use concerns your taste buds. Citric acid gives soft drinks like soda their characteristic flavor. While it is true that citric acid is present in citrus fruits, almost all of the citric acid used today relies on the ability of aspergillus to ferment. To do this, scientists feed sugar or molasses to Aspergillus niger and then collect the citric acid that the combination produces as a product of fermentation. Fortunately, microbiologists only harvest the citric acid and not the black mold itself, so the foods and drinks that require citric acid are completely safe to consume, even for people with mold allergies or who are at risk for aspergillosis
