What is earthobate?

Answer 1

There is no such stuff as "earthobate". It is a misspelling of erythorbate. Sodium erythorbate (a closely related chemical to vitamin C) is an antioxidant and used in foods to prevent colour and texture changes caused by air.

Answer 2

I'm not familiar with the term "earthobate." It does not appear to be a standard English word. Could you provide more context or clarify so I can better assist you?
