2. Application

Used in food

l Sodium Bisulfite food grade is used in almost all commercial wines to prevent oxidation and preserve flavor;

l In fruit canning, sodium bisulfite is used to prevent browning (caused by oxidation) and to kill microbes.

l Sodium bisulfite food grade is also added to leafy green vegetables in salad bars and elsewhere, to preserve apparent freshness

Industrial uses

l Sodium bisulfite is a common reducing agent in the chemical industries.

l It is usually added to large piping systems to prevent oxidative corrosion.

l In biochemical engineering applications, it is helpful to maintain anaerobic conditions within a reactor.

l In wastewater treatment, sodium bisulphite is often added following disinfection with a chlorine solution to neutralize the residual chlorine before discharging the treated effluent.
