In addition to 0 liters, 24
The saponified crude n-hexane extract of the upper layer obtained by removing the lower layer liquid part separated into two layers and leaving it in a saponification treatment for a period of time is placed in 100 liters of water at room temperature. Washing with agitation and removing the washing liquid such as chlorophyll
-The hexane extract is subjected to vacuum distillation at 5 to 10 -2 mmHg and 50 ° C, and then n-
To 300 liters of the crude n-hexane extract containing hexane, 1 to 10 liters of ethanol and 1 to 5 liters of water were added, and the mixture was distilled at 30 to 60 ° C. to extract β-carotene oil-containing extract from Donariella alga bodies. This is a method for extracting Donariella algae, which comprises obtaining a liquid. [Detailed Description of the Invention] In the washing treatment of the present invention, 10 to 200 kg of the powder of Donariella algae is added to 400 to 1 of ethanol.
For immersion in 000 liters, washing by stirring, for 10 to 200 kg of Donariella algae body powder, with less than 400 liters of ethanol, the immersion state becomes a mud state,
The effect of washing by stirring cannot be obtained, and washing can be performed even when the amount exceeds 1000 liters. However, it is not economical because ethanol is wasted. Because it would be uneconomical, 40
It is preferable to wash at 5959 ° C. for 30 minutes to 1 hour 30 minutes. In the extraction treatment, n-hexane 1200 to 15

It is preferable to use 00 liters, and
The stirring process for 30 minutes to 1.5 hours while heating at 0 to 60 ° C. is performed when the temperature range of 40 to 60 ° C. is n-
The solubility of β-carotene dissolved in hexane increases,
In addition, the extraction time in the range of 30 minutes to 1 hour 30 minutes is preferable. In the removal treatment of chlorophyll and the like, 30 l of the crude n-hexane extract obtained by the extraction treatment
The reason why the mixture is mixed with 10 liters of 0.5N ethanol solution of potassium hydroxide and saponified for 24 hours while heating at 40 to 60 ° C. is that saponification is sufficiently performed. 28. A saponification-treated crude n-hexane extract (deethanol-free crude n-hexane extract) of the upper layer obtained by separating the lower liquid layer separated into two layers after the saponification treatment. 5
2929.5 liters in 100 liters of water, stirred and washed with water, chlorophyll, potassium hydroxide, saponified substances and the like were suitably washed away with water, and 27.0-29.0.
One liter of crude n-hexane extract is obtained.
300 liters of the crude n-hexane extract from which chlorophyll and the like have been removed by desolvation treatment is added at 5 to 10 -2 mmHg
Vacuum distillation at 50 ° C. is performed by adding 1 to 10 liters of ethanol and 1 to 5 liters of water to 300 liters of an n-hexane extract of a solvent and performing distillation at 50 ° C. to remove the remaining n. This is because hexane can be suppressed to 10 to 20 ppm. The Donariella alga body in the present invention means Donariella bardawill, Donaliella salina and other Donariella alga bodies, especially dry powder of the Donaliella alga body, and the explosion-proof tank uses ethanol, and there is a possibility of explosion when heated. It is preferably used in such a case, and is preferably provided with a liquid outlet pipe having an on-off valve at the bottom.
