Spirulina extract and preparation thereof

The invention provides extracting solution for a spirulina maxima and a preparation method thereof. The nutrient content in the extracting solution mainly comprises chlorophyl of the spirulina maxima, phyeoeyani of the spirulina maxima, and polyhexose of the spirulina maxima, and so on, wherein the content of the chlorophyll of the spirulina maxima is higher than 8 percent. The preparation methodmainly comprises the processes of extracting the chlorophyll, extracting the phyeoeyanin, extracting free amino acid, oligopeptides and oligose, and extracting the polyhexose of the spirulina maxima,and so on; particularly, the gummeline embedding process is performed in the process of extracting the chlorophyll of the spirulina maxima. The preparation method extracts sufficiently, reserves the ingredient of the chlorophyll of the spirulina maxima, can be applied to the beverage addition, particularly the beer addition, does not pollute the environment, has convenient operation and is easilyapplied to the industrial p
