Usually yes — despite the name, commercial lactic acid is made by fermenting sugars.

关键事实

最佳替代品: Certified vegan alternatives

为什么

It is produced from corn, beet or cane sugar with bacteria, not from milk. The confusion comes from the Latin for milk. The rare exception is lactic acid in a dairy product, where the milk itself is the issue.

常见问题

Is Lactic acid (E270) certified vegan?

Certification is separate from the recipe. Many products with no animal ingredients carry no vegan mark because the maker will not rule out shared production lines. Check the pack for a registered vegan trademark, and treat the ingredient list as the primary evidence.

Does the answer change between countries?

Often, yes. The same brand name can use different fats, emulsifiers, colours or whey depending on the plant that made it, so always read the local label rather than an answer written for another market.
