Filed: 2011-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for industrially and efficiently producing highly pure astaxanthin without affecting a production amount of chitin in a process for producing chitin from shells of crabs and shrimps.SOLUTION: In the process for producing chitin from shells of crabs and shrimps, after removing calcium by hydrochloric acid soaking performed therein, ethanol is added to the shells of crabs and shrimps washed with water without carrying out neutralization so that a final concentration of ethanol becomes not higher than 70%. Astaxanthin is extracted by soaking the shells of crabs and shrimps in the solution for several hours while heating the solution. An extract and the shells of crabs and shrimps are separated from each other, and the shells of crabs and shrimps are returned to the process for producing chitin. After a deproteinization process of soaking in a sodium hydroxide solution, chitin is produced. When ethanol is removed by reduced pressure treatment after adding edible oil to the extract containing astaxanthin, astaxanthin is dissolved and spread in the edible oil, and then, an edible oil layer is collected to obtain an astaxanthin-containing oil.
