What does acidulating mean?
Acidulating is the present participle of acidulate, a verb meaning to make something acidic or to treat it with acid. In technical writing, it describes a deliberate chemical step: a laboratory might acidulate a sample, a manufacturer might acidulate a solution, or a food producer might use an approved acid to adjust a product's acidity. The word is more specialized and less familiar than acidify, although the two are close in meaning; acidulating can suggest treating a material with acid as well as lowering its pH. Because it ends in -ing, acidulating can be used either as a gerund, naming an action, or as a participle modifying a noun, as in “acidulating solution.” It is used in British and American English and carries no special positive or negative connotation. Its usefulness lies in making explicit the process by which acidity is introduced rather than merely describing the result.
