摘要
本研究以桦褐孔菌多糖为原料,并辅以蔗糖、柠檬酸、羧甲基纤维素钠与黄原胶以及复合维生素基料,利用响应面试验优化桦褐孔菌多糖复合运动饮品的最佳加工工艺。利用Fenton反应法,邻苯三酚自氧化法以及1,1-二苯基-2-三硝基苯肼(DPPH)比色法分析桦褐孔菌多糖复合饮品对羟基自由基(·OH)、超氧阴离子自由基(O2-)和DPPH自由基的清除能力。得到最佳工艺条件为桦褐孔菌多糖添加量2.1%、蔗糖添加量6.0%、柠檬酸添加量0.15%,并添加0.10%复配稳定剂后,制得的饮品颜色透亮,酸甜适中,口感爽滑。抗氧化试验表明,1 mL的复合饮品对·OH、O2-和DPPH·的清除率分别为52.13%、40.26%、36.23%。可见桦褐孔菌多糖复合运动饮品具有良好的抗氧化活性,试验结果为桦褐孔菌的产品开发及深度利用提供理论依据。
Inonotus obliquus polysaccharide was used as raw material,supplemented with sucrose,citric acid,sodium carboxymethyl cellulose,xanthan gum and compound vitamin base material. The response surface method was used to optimize the processing technology of Inonotus obliquus polysaccharide compound sports drink. Fenton reaction method,pyrogallol autooxidation method,and 1,1-diphenyl-2-trinitrophenylhydrazine(DPPH)colorimetric method were used to determine the scavenging ability of Inonotus obliquus polysaccharide compound drink on hydroxyl radical( · OH),superoxide anion(O2-),and DPPH,respectively. The optimum technological conditions were as follows :2.1% of Inonotus obliquus polysaccharide,6.0% of sucrose and 0.15% of citric acid,and 0.10% compound stabilizer. The drink prepared with the optimum conditions above,had bright color,moderate sweetness and acidity,and smooth taste. The antioxidant test showed that the scavenging rates of 1mL Inonotus obliquus polysaccharide compound drink on · OH,O2-and DPPH · were 52.13%,40.26%,and 36.23%respectively. It showed that Inonotus obliquus polysaccharide compound sports drink had good antioxidant activity. The study provides a theoretical basis for the products development and more applications of Inonotus obliquus.
