NaOH breaks it while sulfite ion accelerates the rate of delignification by making smaller fragments of lignin which then make stable salts of sodium.
Although the sulfite ion (S[0.sub.3 sup.-]) can bind with oxygen, there is very litle sulfite ion present in solution at the pH range found in wine (see Figure I).
Selective measurement of sulfite ion requires HPLC method, which in addition to the high price of the equipment, needs the use of expensive solutions that are harmful to the environment.
