Gentlemen,

Really - I made with mistake with transliteration: the chemical stated in the book and the one I used is Sodium Benzenesufinate. And I assume the polish literation is the same.
I tried to look for different sources about sulfonate and sulfinate, and it seems that both of them can be used as ani-oxidants. There is not much info unfortunately.

Thanks for the confirmation, Pavel.
