Optimizing Technique of Extracting Polysaccharide from Gracilaria

Abstract

Abstract: Objective: optimizing technics of extracting polysaccharide by general method from Porphyra haitanensis. Method: L16(44) quadrature enhancing experiment. Result: the concentration of alcohol was the main factor which effected the extracting rate of Porphyra haitanensis polysaccharide, extracting time was the secondly factors, then was the extracting temperature and ratio of material with liquid. Conclusion: the prime technics was as follows: concentration of alcohol 60%, time 1.5h, temperature 80℃ and the ratio of material with liquid 1:50.

Key words: Porphyra haitanensis, polysaccharide, extracting technics, optimizing
