The invention discloses a plant superoxide dismutase oxygen enrichment catalysis large scale producing method. It includes the following steps: selecting plant seed; removing impurity; sterilizing; oxygen enrichment pre-catalyzing; catalyzing; homogenization treatment and control pH at 7-8; dehydrating and collecting feed liquid; filtering and drying. Its advantages are that it can improve superoxide dismutase yield, increase its recovery by 30-50% compared with the existing method; it has simple technology, low cost, and wide material adaptability; it can used in large scale production. |
