响应曲面法优化麒麟菜卡拉胶碱处理工艺
采用响应曲面法研究了碱液质量浓度、浸泡时间和浸泡温度对麒麟菜（Eucheuma）卡拉胶的凝胶强度和产率的影响。在单因素试验基础上采用Box—Benhnken中心组合试验，以碱液质量浓度、浸泡时间和浸泡温度为影响因素，以凝胶强度和产率为响应值建立二次回归方程，通过响应面分析得到优化组合。结果显示，碱处理优化工艺参数为碱液质量浓度250g·L-1、浸泡时间3．5d和浸泡温度25℃，在此条件下提取的麒麟菜卡拉胶凝胶强度为721g·cm-2（质量浓度10g·L-1），产率为35．17％。...

| Bibliography: | We studied the influence of 3 factors including alkali concentration, soaking time and temperature on gel strength （GS） and yield of Eucheuma carrgeenan by response surface methodology （RSM）. On the basis of single-factor investigation, Box-Benhnken central composite experiments were carried out to build the quadratic regression models for GS and yield with the above 3 factors, and the alkali processing technology was optimized by response surface analysis. The optimizing process parameters are： alkali concentration 250 g.L-1 , soaking time 3.5 d, soaking temperature 25℃. Under the optimal processing condition, the GS and yield of carrgeenan were 721 g.cm-2 （under concentration of 10 g.L-1） and 35.17% , respectively. carrgeenan ; Eucheuma ; response surface methodology ; gel strength ; yield QI Bo, LI Laihao , YANG Xianqing , CHENG Shengjun , LIU Gang , LI Zhandong （1.
