E353 Metatartaric acid — is it halal?

Description

A polyester of tartaric acid: it is heated above 150 °C and the molecules cross-link with loss of water. The commercial product is a mixture of chains of various lengths, free tartaric acid (9–18%), pyruvic acid (1–6%) and about 20% water. It is used almost exclusively in wine, to stop tartrates from precipitating — precisely what cards E 336(i) and E 354 are about.
