Chickpea residue is used as feed, fertilizer, or being abandoned that may cause serious waste of resource. Chickpea residue contains some water-insoluble dietary fiber. The residue was treated by acid combined with alkali. The optimal extraction of chickpea water-insoluble dietary fiber was obtained by orthogonal experiment. The result showed that the alkali dosage was 5 mL/g, alkali treatment time 70 min, temperature 80 ℃, acid dosage 2 mL/g, acid treatment time 80 min. The nitrite content in luncheon meat can be decreased significantly by adding 1.0 % chickpea dietary fiber.
