Provided is a preparation method for phycocyanin, including: adding chitosan to a suspension of cyanobacteria containing phycocyanin; and filtering the suspension.

Method for preparing phycocyanin

A first method for producing glucan comprises the step of allowing a reaction solution containing sucrose, a primer, inorganic phosphate or glucose-1-phosphate, sucrose phosphorylase, and glucan phosphorylase to react to produce glucans. The maximum value of the sucrose-phosphate ratio of the reaction solution from the start of the reaction to the end of the reaction is no more than about 17. A second method for producing glucan comprises the step of allowing a reaction solution containing sucrose, a primer, inorganic phosphate or glucose-1-phosphate, sucrose phosphorylase, and glucan phosphorylase to react to produce glucans. The reaction is conducted at a temperature of about 40 C to about 70 C.
