| Abstract: | The different extracting methods for polysaccharide of Gracilaria lemaneiformis were investigated,that was based on the comparison between microwave extraction and hot water extraction. Results showed that the extraction rate of polysaccharide by microwave extraction was better than that by hot water extraction. The extraction rate was up to 27.6% more than 19.6% of the extraction rate by hot water extraction. The best parameters of technology was determined through orthogonal test, then using microwave extraction method to obtain polysaccharide of Gracilaria lemaneiformis. The optimum conditions of extraction were obtained as follows: adding 100 times water as much as lemaneiformis in 600 W for 6 minutes. |
