Study on extraction methodology of alginates from Scytosiphon Iomentsrius and its rheological characteristics
摘要
Abstract
Extraction method and the optimal bleaching condition of alginates from Scytosiphon Iomentsfius and their rheological characteristics were studied in this research. The results indicated that the optimal bleaching condition was conducted as follows-4% of sodium hypochlorite solution with pH of 10.5 was added to the alginate solution with a ratio of 3:600,and heated at 35℃ for 40min. The viscosity of sodium alginate solution from Scytosiphon Iomentsrius decreased with increasing of shearing rate,thus the sodium alginate solution behaved as pseudoplastic fluid and had thixotropism. The sodium alginate solution from Scytosiphon Iomentsrius possessed viscoelasticity,which primarily behaved viscocity in the low frequency area system and elasticity in the higher one. Furthermore,the viscosity of the sodium alginate solution also was influenced by temperature and the concentrations of alginate,salt and sucrose.关键词
