Hello, according to the Canadian regulations, Salt sold to consumers in Canada for table and household use must be iodized with 0.01% potassium iodide. My understanding was that iodisation of salt is the primary goal, whatever the means. However, since the regulation specifically mentions "potassium iodide", does that mean we cannot use potassium iodate as the source of iodine?
We have been producing iodised salt with potassium iodate, but have been unable to come up with a stable product while using potassium iodide.
To summarise, I want to know if:
a) Salt iodised with potassium iodate can be sold in Canada?
b) How to stabilise and prevent iodine liberation when using potassium iodide as the source of iodisation of salt?
Any help from the experts would be highly appreciated! :)
