Extraction method of water-soluble spirulina phycobiliprotein

Abstract

The invention relates to an extraction method of water-soluble spirulina phycobiliprotein. The extraction method of the water-soluble spirulina phycobiliprotein comprises the following steps: soaking a spirulina raw material into water, stirring and freezing the solution at a temperature of 20 DEG C below zero for 48 hours, taking out and rapidly melting the frozen matter, centrifugating and filtering the solution, extracting the phycobiliprotein from the centrifugal liquid and remaining the spirulina dreg for extracting spirulina polysaccharide; and purifying, concentrating, spraying and drying the obtained centrifugal liquid into the spirulina phycobiliprotein. The extraction method of the water-soluble spirulina phycobiliprotein is simple to operate; the extracted spirulina phycobiliprotein is water-soluble powder so as to be easy for human bodies to desist and absorb, and the water-soluble powder can be further processed to be used as a raw material of food additives, functional foods and medicaments, a natural blue pigment of foods and cosmetics, and the like, thereby having wide serviceable range; and the pretreated spirulina dreg in the extraction process can be remained for extracting the spirulina polysaccharide so as to improve the utilization rate of the spirulina raw material.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for extracting water-soluble spirulina phycobiliprotein. Background technique [0002] Spirulina is the cyanobacteria in microalgae, it has the characteristics of high protein, low fat, low sugar, low cholesterol, contains a variety of vitamins, proteins, fats, carbohydrates, minerals and trace elements, and various proportions are scientific and reasonable, of which Many ingredients reach the content and strength of the drug, which makes it have a wide range of medicinal functions. It can promote human metabolism, improve the body's immunity, improve physical fitness, resist radiation, assist cancer radiotherapy and chemotherapy, and reduce the side effects of radiotherapy and chemotherapy. It has positive effects and is an ideal pure natural bioactive health food. Therefore, it is recommended as "the most ideal food in the 21st century" by the Food and Agriculture Organiz...
