In this paper,single factor test and response surface method were used to optimize the preparation process conditions of polysaccharide iron from waste fungus sticks.The structure of polysaccharide and polysaccharide iron from waste fungus sticks was preliminarily characterized by infrared spectrum scanning electron microscopy,and the antioxidant activities of polysaccharide and polysaccharide iron from waste fungus sticks were studied.The results showed that when the reaction temperature was 50 ℃,the amount of ferric chloride was 0.7 mL,and the pH value was 9.0,the iron content of polysaccharide from waste fungus sticks was the highest(8.17%).The antioxidant activity of polysaccharide iron from waste fungus sticks was significantly higher than that from waste fungus sticks.
