Is E327 Vegan?
E327 (Calcium Lactate) may or may not be vegan — it depends on the source. It is the calcium salt of lactic acid, usually from plant fermentation, and the ingredients label never tells you which source was used.
Why is E327 uncertain?
The calcium salt of lactic acid, usually from plant fermentation. Manufacturers can legally use either source and simply list 'E327' or 'Calcium Lactate' on the label. In practice most modern production is plant-based or synthetic, but without confirmation from the manufacturer or a vegan certification logo, you can't be sure.
What can vegans look for instead?
The safest options are: (1) choose products carrying a certified vegan logo, which guarantees a plant or synthetic source was used; (2) contact the manufacturer and ask directly about the source of E327; or (3) choose products that don't list E327 at all.
Is E327 vegetarian?
Possibly not — like its vegan status, the vegetarian status of E327 depends on whether an animal or plant source was used, which the label doesn't reveal.
Frequently Asked Questions
Is E327 always non-vegan?
No — E327 is often plant-derived or synthetic, and in many products it is vegan. The problem is that the label doesn't distinguish, so each product needs verifying.
How can I tell if E327 is vegan in a specific product?
Check for a certified vegan logo on the packaging — that's the only label-level guarantee. Otherwise contact the manufacturer's customer service and ask specifically about the source of E327 in that product.
Are there vegan-friendly versions of E327?
Yes — plant-based and synthetic versions of E327 are common, and products with vegan certification will always use them. The label alone just can't tell you which version a given product contains.
