What does lactated mean?
Lactated is an uncommon inflected form with two main uses. As an adjective, it describes a substance that contains lactose or that has been subjected to lactose fermentation, as in “lactated milk.” In its verb use, it is the past tense and past participle of lactate, meaning to produce or secrete milk. The word is therefore associated both with the chemistry of milk and with the biological process of milk production. It occurs more often in technical, scientific, or food-related writing than in ordinary conversation. Its distinctive vocabulary value lies in connecting milk, lactose, lactic acid, and fermentation, while the related forms lactate, lactic, and lactose help make its broader family easier to remember.
