Abstract:Beacuase of harm of nitrite to human，it was substituted by a variety of natural food additives according to our experimental results to enhance food security.As nitrite substitutes，the food additives include Nisin，sodium diacetate（SDA），monascus red pigment，caramel，butyl hydroxy anisd（BHA），butylated hydroxytoluene（BHT），and so on.The results showed that nitrite could be completely substituted by a set of nitrite sub stitutes.Inthesetofnitritesubstitute，200mg/kgNisinmatchedwith1200mg/kgSDAaspreservatives，200mg/kg monascus red pigment matched with 20 g/kg caramel as colorants，100 mg/kg BHA matched with 100 mg/kg BHT as antioxidants，60 mg/kg vitamin C and 60 mg/kg as antioxidant additives and 1.5 g/kg sucrose fatty acid ester as emulsifying additives play antibacterial，coloring and antioxidant roles.
