摘要：
The present invention provides a method for conveniently obtaining a biodegradable polyhydroxyalkanoate by a solvent extraction method. A method for producing a polyhydroxyalkanoate crystal comprises precipitating a polyhydroxyalkanoate crystal using a monohydric alcohol having 4 to 10 carbon atoms as a extraction solvent, keeping a polyhydroxyalkanoate solution containing 0.1 to 10% by weight of water relative to the total amount of the solution warm at 70° C. or higher, and cooling the solution to below 70° C.
