BACKGROUND OF THE INVENTION Single-cell green algae of the genus Chlorella (hereinafter referred to as "Chlorella") have a high protein content and a large amount of useful amino acids, and are therefore used as raw materials for so-called health foods or feeds. Specifically, a chlorella extract solution extracted from chlorella or an extract powder obtained by drying this extract solution is provided as a material, and health foods are manufactured in the form of tablets, beverages and the like.

By the way, it is said that it is essential that the liquid used as a beverage material does not have a solid content that precipitates. However, the extract liquid extracted from Chlorella contains lipids and other substances dispersed in the liquid. There are floating solids,
As it is, it is not preferable as a beverage material. Further, the extract powder obtained by drying this extract solution also has very poor solubility because it contains these solids, and is not suitable as a beverage material. The reason why chlorella extract is not widely spread, although its effectiveness is recognized, is largely due to the poor solubility of the extract powder.

[0004] Furthermore, the chlorella extract liquid contains a small amount of pheophorbide as one of the lipids to be dispersed, but this substance is one of the decomposition products of chlorophyll and is a causative substance of photosensitivity. It is a known harmful substance. Therefore, the presence of such an insoluble solid content in the liquid is not desirable in terms of safety. Therefore, attempts have conventionally been made to remove lipids and other suspended solids by centrifugation or membrane separation.

However, in the centrifugal separation method, suspended solids cannot be sufficiently separated even if batch processing is performed at 10,000 G for 1 hour. Therefore,
The supernatant obtained by the centrifugation method contains a considerable amount of solids, which is not satisfactory as a beverage material. In addition, since the insoluble solid content is contained in the liquid, the extract powder prepared from this supernatant liquid still has poor solubility.

The crude fat content and the pheophorbide content of the raw powder, the supernatant powder and the lower layer powder were measured. For the original powder and the supernatant powder, add 1% by weight to water to suspend, centrifuge at 2,000 G for 20 minutes, and then add water to each settling part to wash the precipitate weight ( The suspended solids were weighed by measuring (wt%).
