Abstract

The invention discloses a method for extracting phycocyanobilin from spirulina. The method comprises the following process steps: A, dissolving the fresh spirulina in sterile deionized water in the ratio of 1:(10-30) and repeatedly freezing and thawing for three times; B, adding the spirulina liquid to a high-pressure homogenizer and circularly homogenizing for 2-3 times in the state of 20-40Kpa; C, adding the homogenized spirulina liquid to an ultrasonic crusher and crushing the cell walls of the spirulina by use of ultrasonic waves to dissolve out the phycobiliprotein, and extracting the liquid; D, centrifuging the wall-crushed extract for 20-40 minutes, removing cell debris, and obtaining thewater phase as the phycocyanobilin extract; E, concentrating the phycocyanobilin extract in a tubular ultrafiltration membrane filter system to obtain spirulina pulp, wherein the molecular cutoff of the membrane is smaller than 150000 Da and the concentration multiple is 10-15; and F, performing spray-drying on the spirulina pulp under the condition that the temperature is 180 DEG C, thereby obtaining a phycocyanobilin dry powder product.

Description

technical field [0001] The invention relates to the technical field of biological extraction, in particular to an extraction method for extracting phycocyanin from spirulina. Background technique [0002] Phycocyanin can improve the activity of the lymphatic system, enhance the body's immunity, resist tumors, promote the proliferation of hematopoietic cells and bone marrow cells, and significantly reduce the damage of radiation to peripheral blood cells and bone marrow cells in mice. It has good health care functions and auxiliary curative effects. Spirulina soluble polysaccharides have the functions of improving the body's immunity, anti-radiation and anti-cancer. In addition to being used as a medicine, phycocyanin, as a water-soluble blue pigment, has a wide range of applications and is an additive for various high-end foods. It not only has bright colors, but also has health care effects. [0003] In recent years, my country's spirulina factories have developed rapidly....
