利用完全正交实验法对海水提取龙须菜琼胶工艺中的碱处理时间、温度及碱液浓度进行对比研究，通过对琼胶样品中的硫酸基含量、出胶率和凝胶强度的测定，分析不同碱处理条件对龙须菜琼胶产品质量的影响．实验结果表明，利用海水提取龙须菜琼胶的最佳碱处理条件：碱处理温度90℃，碱液浓度8％，碱处理时间60min．此条件处理所得的龙须菜琼胶产品的平均凝胶强度比标准的琼胶样品的凝胶强度高69．08g·cm^-2．

The treatment time, temperature and alkali concentration for alkali treatment of agar extraction meth- ment method. The sulfate content, agar yield percentage, and the gel strength of agar from G. lemaneiformis were detected in order to evaluate the influence of different alkali treatment conditions on the product quality of Gracilaria agar. The results showed that the optimal conditions of alkali treatment for the extraction of agar from G. /emane/form/s using seawater were as the following: alkali treatment temperature of 90 ℃, the alkali concen- tration of 8%, and the alkali treatment time of 60 min. The gel strength of the agar extracted under the condi- tions was 69. 08 g · cm-2 higher than the standard agar samples.
