本文采用三种碱处理方法对细基江蓠原变型、混养细基江蓠繁枝变型和单养细基江蓠繁枝变型进行了对比研究。得出“中温浓碱法”为提高三种江蓠琼胶凝胶强度的较好工艺,而“常温浓碱法”的产率较好.“中温浓碱法“三种江蓠琼胶的产率及凝胶强度分别为(次序同上,下同):38.6%、691g/cm~2、13.1%、637g/cm~2,13.9%、557g/cm~2,“常温浓碱法”,三种江蓠琼胶的产率及凝胶强度分别是:47.6%、509g/cm~2,19.5%、414g/cm~2,25.9%,326g/cm~2。 In this paper, three kinds of alkali treatment methods were used to compare the original variation of Pinus elliottii, Pinus mutants of Pinus elliottii and Pinus koraiensis variant of Pinus tabulaeformis. The results showed that “moderate temperature and strong alkali method” is a good process to improve the agar gel strength of three kinds of Jiangli, while the yield of “normal temperature and concentrated alkali method” is better. The gel strengths were as follows: 38.6%, 691g / cm ~ 2, 13.1%, 637g / cm ~ 2, 13.9%, 557g / cm ~ The yields and gel strengths were 47.6%, 509 g / cm ~ 2, 19.5%, 414 g / cm ~ 2, 25.9%, 326 g / cm ~ 2, respectively.
