Abstract
The invention relates to the field of recycle of agricultural and sideline products, and in particular to a method for recovering and extracting SOD from conifer cherry residues. The method comprisesthe following steps: pre-treating and crushing conifer cherry residues serving as raw materials to obtain crushed powder; carrying out ultrasonic crushing and leaching, carrying out filtering, and removing filter residues to obtain a filtrate; carrying out grading filtration and interception in cooperation to obtain a crude extract; and refining SOD in the crude extract, and freeze-drying the refined SOD solution to obtain SOD powder. The method disclosed by the invention can be used for efficiently and rapidly recovering and extracting SOD in conifer cherry residues; the method is simple andefficient, and has low requirements on equipment; and the extraction rate of SOD is high, and the extracted SOD has a higher purity and high specific activity.
