Phospholipase — Hidden Processing Agent — Is It Vegan?

Vegan status: Depends on Source

Also known as: Lecithinase, Phospholipase A2 (PLA2), Phospholipase C

Source

Can be derived from: (1) porcine pancreas — extracted from pig pancreatic tissue [not vegan], (2) microbial fermentation from fungi or bacteria [vegan], (3) recombinant production in yeast [vegan]. Microbial phospholipase now dominates industrial applications.

Used in

Breadmaking (modifies lecithin in egg yolk or added lecithin to improve emulsification and dough stability), cheese production (modifies fat globule structure), vegetable oil degumming (removes phospholipids from crude oil).

Appears on label: No. Listed as 'enzyme' or 'phospholipase' where declared. Not required on labels when used as a processing aid at carry-over levels.

How to avoid

Microbial phospholipase is vegan and is the commercial standard. Porcine PLA2 (from pig pancreas) is still used in some applications but is less common commercially. Contact manufacturers for confirmation if required.

Notes

Phospholipase A2 from porcine pancreas was historically the primary commercial source — it converts lecithin into lysolecithin, which is a significantly better emulsifier. Modern applications increasingly use recombinant phospholipase produced in yeast or bacterial fermentation systems, making the source entirely non-animal. The egg-free breadmaking industry is a significant application area.
