But is it Vegan ?
I’m trying to find that out too. I emailed the company Silk to find out if the calcium carbonate they use in their soy milk is biological (not vegan) or geological (vegan). Anyone out there know? Haven’t heard back from Silk yet.
Our almondmilk, soymilk, coconutmilk, cashewmilk, blends, creamer products and yogurt alternatives are completely vegan! There are no animal products, by-products or derivatives in these products, and the calcium we use in these products is derived from natural limestone.
Silk FAQs for Soymilk, Almondmilk, Coconutmilk
I see no ethical problem to use limestone to enrich all these products in calcium carbonate. However, it seems that limestone is a product of the aggregation of coral, foraminifera, and molluscs skeletons. And those organisms are part of the animal kingdom.
But I think there is no ethical question here! ^^
