A substance or agent that prevents or inhibits fermentation in biological or chemical processes.
From anti- (against) + ferment (from Latin fermentum, meaning 'leaven' or 'to boil'). The term developed in food science and microbiology as preservation techniques were studied and refined in the 19th-20th centuries.
Before refrigeration, antiferments were literally the difference between eating fresh food and eating rot—salt, sugar, and acid were the chemical weapons that preserved whole civilizations.
