E270 — Lactic acid

No concern

E270 (Lactic acid) raises no animal-source question. A mild sour acid, despite a name that suggests milk.

Why it raises no question

It is made by fermenting plant sugars. Even when a dairy route is used, milk is permissible, so neither source raises a question.

Where you meet it

Bread, pickles, drinks, sweets, dressings.
