细基江蓠原变型与细基江蓠繁枝变型制取琼胶的比较研究

A COMPARATIVE STUDY ON THE PRODUCTION OF AGAR FROM GRACILARIA TENUISTIPITATA ZHANG ET XIA F. TENUISTIPITATA AND GRACILARIA TENUISTIPITATA ZHANG ET XIA F. LINI ZHANG ET XIA, F. NOV.

摘要:

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/cm²、13.1%、637g/cm²,13.9%、557g/cm²,"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/cm²,19.5%、414g/cm²,25.9%,326g/cm²。

Abstract:

In this paper there is a comparative study between the Gracilaria tenuistipitata zhang et Xia f. tenuistipitata, the mixed culture Gracilaria tenuistipitata zhang et Xia f. Lini zhang et Xia, f. nov. and the monoculture Gracilaria tenuistipitata zhang et Xia f. Lini zhang et Xia,f. nov. by three different alkali-treatment methods. It is indicated that the high-concentration alkali warm treatment is the best way for improving congealed-gum strength on the three Gracilaria. The production rate and strength of these Gracilaria are 38.6%, 691g/cm; 13.1%, 637g/cm; 13.9%, 557g/cm; respectively under this condition. The high concentration alkali cold treatment for improving production rate is the best way. The production rate and strength are 47.6%, 509g/cm; 19.5%, 414g/cm; 25.9%, 326g/cm respectively un der this condition.
