2.Methods The Se-PSP was obtained from ASW,a sort of culture medium added with some selenious acid solution,and was purified by DEAE-52 cellulose column and identified by Sephadex G-200.The acidity,UV spectral absorption,paper chromatography,and gelose electrophoresis of Se-PSP solution were studied.
方法在ASW培养基中加入适量的亚硒酸制备硒化紫球藻胞外多糖,并通过DEAE-52树脂分离纯化,Sephadex G200层析法鉴定其纯度; 硫酸苯酚法测定硒化紫球藻多糖溶解度;收藏指正
3.The Function Property and digestibility of acetylated ae maize starches (Hi - Maize, 66% amylose and GELOSE 50, 47% amylose), wx maize starch(MAZACA 3401X, 3. 3% amylose), normal maize starch (22. 4% amylose)provided by Starch Australasia Limited were studied. Acetylation decreased temperature at peak viscosity, while increasing peak viscosity compared to native starches.
对StarchAustralasia公司提供的直链扩增玉米淀粉（Hi－Maize，直链淀粉含量66％，GELOSE50，直链淀粉含量47％），蜡性玉米淀粉（MAZACA3401X，直链淀粉含量3．3％），和正常玉米淀粉（直链淀粉含量22．4％）进行乙酰化反应，并对其功能性质和酶解率进行研究，乙酰化反应降低所有淀粉的糊化温度，同时增加淀粉的粘度。收藏指正
