General description
Sodium hypophosphite, also known as sodium phosphinate, is a sodium salt of hypophosphorous acid. It is used as a reducing agent for the reduction of metal salts to metals in an aqueous solution. It is also employed as a source of hydrogen in heterogeneous catalytic transfer reductions.

Nitrite-free and low-nitrite meat-curing systems were developed to eliminate or reduce nitrite in frankfurter-type sausages. Different composite meat-curing mixtures were formulated using cochineal and paprika as natural colorants, sodium hypophosphite (SHP) as antimicrobial agent, butylated hydroxyanisole (BHA) as antioxidant and
