Abstract

In this paper, the use of ultrasound-assisted extraction of polysaccharides from Gracilaria discussed ultrasonic power, ultrasonic time, four factors affect the extraction temperature and ratio of liquid to solid on the extraction rate, test results show that: with the increase of liquid ratio, the dragon shall dishes polysaccharide extraction rate is also rising, the impact of ultrasonic power on extraction of polysaccharide from Gracilaria increases after ultrasonic power and the first increase in a downward trend in the ultrasonic power between 280-320W to achieve the best, with the increased ultrasonic time, the extraction rate of polysaccharide from Gracilaria presented firstly increased and then decreased. With the improvement of ultrasonic temperature, the extraction rate of polysaccharides from Gracilaria showing a decreasing trend after the first increase in about 55°C maximum extraction rate of 40.1%, indicating that the asparagus dish suitable ultrasonic temperature at about 55°C.
