Abstract

The invention discloses a microwave extraction method for spirulina polysaccharide. The method mainly overcomes the problems of great consumption of time and energy and low yield in extraction of spirulina polysaccharide with conventional hot water methods and cold alkali methods The microwave extraction method comprises the following steps: adding spirulina powder into distilled water according to a material-liquid ratio, carrying out ultrasonic treatment, then carrying out microwave extraction by using an intermittent microwave extraction method and then carrying out centrifugation so as to obtain crude spirulina polysaccharide extract; adding the crude spirulina polysaccharide extract into a trichloroacetic acid solution to remove protein; and then adding active carbon TS4 for decoloring and carrying out vacuum freeze drying so as to obtain the spirulina polysaccharide. The microwave extraction method has the advantages of reasonable extraction process, mild polysaccharide extraction conditions, no destroy to effective components, high extraction efficiency, thorough removal of impurities, ideal yield and suitability for large-scale factory production.

Description

technical field [0001] The invention relates to the preparation of polysaccharides, in particular to a microwave extraction method of spirulina polysaccharides. Background technique [0002] We know that Spirulina (Spirulina) is a kind of low-level plant, belonging to Cyanophyta, Oscillatoriaceae, because of its balanced and comprehensive nutrition, it is popular all over the world and has become the best health maintenance food. Spirulina polysaccharide is an extremely important physiologically active ingredient in spirulina. It has unique effects in anti-tumor, anti-virus, hypoglycemic, anti-aging, anti-radiation, anti-coagulation and improving immunity. It has become the current development of spirulina. Hotspots in the research field. At present, hot water method, cold alkali method, etc. are mostly used for the extraction of Spirulina polysaccharides. These methods all have disadvantages such as time-consuming, energy-consuming, and low yield. [0003] Microwave extra...
