摘要
本文采用单因素试验和响应面法优化废菌棒多糖铁的制备工艺条件,采用红外光谱扫描电镜对废菌棒多糖和废菌棒多糖铁结构进行初步表征,并对废菌棒多糖和废菌棒多糖铁的抗氧化活性进行了研究。结果表明,在反应温度为50℃,氯化铁添加量为0.7 mL,pH值为9.0的条件下,废菌棒多糖铁的含铁率最高,为8.17%。废菌棒多糖铁的抗氧化活性明显比废菌棒多糖高。
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.
