Etymology: "Acidulants" is simply the plural of "acidulant," and the singular is the more useful place to start. The word is built from "acidulate," a verb meaning to make slightly acidic, which itself comes from the Latin "acidulus," meaning somewhat sour, a diminutive of "acidus" (sour). The Latin root gives English words like "acid" and "acidic," while the "-ulus" ending shrinks the sense down to "a little sour." The "-ant" ending marks the noun as an agent: a thing that does the acidulating, much as a "stimulant" stimulates. In practice, an acidulant is a food additive such as citric, malic, or tartaric acid, used to add tang to sweets, soft drinks, and preserves, or to sharpen flavour without much sweetness.
