Description of Prios Art It is well known that Chlorella is one of.single cell I algae which grow in fresh water, and it contains protein and the like in a large amount and has various peculiar physiologically active effects, an effect of promoting the growth of animals or microorganisms, an effect of S flavoring foods and an effect of removing foreign odor from foods, and particularly, a hot water-extract of chlorella algae finds applications in a wider range, because it significantly has such growth promoting and flavoring effects and can be used to make a product in the form of a concentrated liquid.

Various products utilizing Chlorella algae have been conventionally developed in view of the usefulness of such V Chlorella algae. They include a variety of products, e.g., i typically, those made by blending a dry powder of Chlorella algae with a garlic powder and molding the blend into a tablet, noodles and procesed marine products containing a hot water-extract of Chlorella algae added and used as a flavoring component and a quality improving agent during production

IA-

I -7 thereof, and health food products made by encapsulating a dry powder or hot water-extract of Chlorella algae together with other nutritious and medicinal ingredients into a gelatin capsule. Thus, the applications of such products utilizing Chlorella algae covers a wide range.

As described above, various Chlorella products have been conventionally developed in view of the usefulness of Chlorella algae. In many cases, however, the prior art Chlorella products have considerations in processing operations in the course of production thereof and suffer from a disadvantage that the effective ingredients contained in Chlorella algae are not necessarily retained in a stable manner. More specifically, in spite of the usefulness of Chlorella algae having been acertained and reported as a result of intellectual examinations and reaserches, there is a problem that when the effective ingredients are utilized to provide a product, it is difficult to retain the effective ingredients in an effective and stable manner, with the result that they cannot be utilized reliably and effectively.

Especially, in making F health food product by utilizing Chlorella algae in combintion with other medicinal starting S materials containing medicinal ingredients or the like with a synergistic effect, it is most important for development of a product to stably and effectively retain medicinal ingredients of individual starting materials,to provide a product, but the prior art products suffer from a problem that in many cases, the medicinal ingredients are stably and effectively not necessarily retainedand the usefulness thereof cannot be sufficiently utilized.

product can be used in various applications, such as for cooking and particularly as a flavoring element for frying. In addition, the homogeneous mixing of the effective ingredient containing materials into the edible fatty oil is to prevent the soft capsule from being swollen and broken.

In the present invention, the hot water-extract of the Chlorella algae may be an extract produced by subjecting a aqueous suspension of fresh Chlorella i algaes from an open-air mass cultivation by an optical synthesis to a heating treatment at a temperature of about 80 to 100 C for a period of 15 to 20 minutes, followed by fractionation of the algae. Typical of the fresh Chlorella algae are single cell algae growing in fresh water such as Chlorella pyrenoid osa, Chlorella vulgasis, Chlorella ollipsoider, Scenedesmus, but it is not intended to be limited thereto. The hot water-extract of Chlorella algae contains various physiologically active substances. proteins and vitamins as well as effective poly-saccharides such as N-f-1, 3 glucan and acidic rhamnan present on cell walls. Alternatively, the hot water-extract of Chlorella algae may be an extract produced by adding and mixing water to an optically synthesized Chlorella algae powder in an amount of about four times as much as such powder and subjecting the mixture to a heating treatment at a temperature of 50 to 120 C for about one hour or more and then to a slow extracting treatment, and suitable hot water-extracts can be also used.

The hot water-extract of fungi may be a hot water extract of fungus body, dry fungi and fungus body powder. For example, use may be made of a Ssuitable hot water-extract such as produced by adding and mixing water to fungus ,:.bVoy powder in i 6 4ei a o an amxunt of. four times as much as such powder and subjecting the mixture to a heating treatment at a temperature of 45 to 120 0

C

for a long period of time, preferably, for 5 to 7 hours. The word "fungi or fungus" referres to a polypore, kawaratake, shiitake and other edible musgrooms.

The tonic medicinal vegetable used may be any of medicinal vegetables which have a nutritive tonic effect, but i especially preferred are garlic, genseng, aloe, ume (Japanese spicot), prickly shrub of the family Aradiaceae, and adlay.

The tonic medicinal vegetable may be used in the proper form of vegetable itself, an exudate or dry powder. The word "exudate" refers to leached liquids resulting from leaching I of the tonic medicinal vegetables by a usual method and slurryi like exudates resulting from grinding the concentrate thereof and vegetable itself in a colloid mill. The dry powder which S may be used include those resulting from a proper pretreatment of vegetables, followed by a proper drying such as a hot air drying, a freeze drying and a spray drying, or those resulting from drying of exudates in a usual method.

Each of the hot water-extracts of the Chlorella algae and r fungi is independently concentrated into a slurry-like Sconcentrated exudate in a concentrator, and the exudates are then blended in a blender together with a clathration material forming a clathrate compound, thereby forming a clathrate blend. It is desired that the clathrate blend is'used in a exudate powdered form obtained by drying in a dryer to the extent of a defined moisture content, followed by pulverization.

The tonic medicinal vegetable may be used as a starting 8 i material in the form of a slurry-like exudate resulting from grinding of each vegetable or its exudate powder together with Chlorella algae in the presence or absence of vitamin E oil in !I a colloid mill.

i| The edible oils which may be used include peanut oil, [i sesame oil, wheat germ oil, rapeseed oil, soybean oil, coconut ji oil, safflower oil, beeswax, and other edible fatty oils.

jj These oils may be used alone or in combinations, when the edible oils are used in combination, it is desired that they are used in the form of an oil emulsified material produced by heating mixing starting edible oils, further adding a heated and dissolved soybean lecithin thereto, if necessary, and stirring and mixing the mixture by a homomixer and cooling it to room temperature.

To homogeneously mix the effective ingredient-containing starting materials of Chlorella algae, fungi and tonic medicinal vegetables with the edible fatty oil, the starting Smixed-exudate powder material of the above-described clathrate ri blend and the exudate or dry powder of the tonic medicinal i vegetable may be homogeneously stirred and mixed with the |i edible fatty oil in a mixer. The means for and the sequence of mixing of individual starting components are not i essential but in general, it is desired that the slurry-like I starting material resulting from grinding of the tonic IJ medicinal vegetable and Chlorella algae is homogeneously mixed *to the edible fatty oil In the presence of a vitamin E oil and then, the starting mixed-exudate powder material of the clathrate blend is homogeneously mixed to the resulting suspension in the oil. The concurrent homogeneous mixing of -9 the effective ingredient-containing exudate of the tonic medicinal vegetable, the starting dry powder material of the clathrate blend and the starting edible fatty oil material may be properly employed.

In grinding the tonic medicinal vegetable and Chlorella alge, the use of a vitamin E oil ensures that physiological activities of the vitamin E and various effective ingredients of the tonic medicinal vegetables can be effectively and stably intensified and maintained.

The oil suspension obtained by mixing the various I starting materials in thi3 manner is then passed through a proper mesh strainer and degassed in a deaerator, following which the resulting mixture is encapsulated into a proper soft capsule such as a soft gelatin capsule, thereby providing an <i intended functional Chlorella-containing fatty oil foodstuff.

It should be noted that the leached liquid of the vegetable can be used for the starting tonic medicinal I vegetable material in the form of a spray-dried material, but r| this is expensive, because water is present in too a large amount in the leached liquid. Therefore, .it is desired that with or without a dry powders of other tonic medicinal vegetable(s) added, the leached liquid is adsorbed to an edible sugar powder such as lactose, starch or the like and the resulting powder material is used. The edible sugar powder such as lactose, starch or the like is properly used in order to absorb water in the leached liquid to provide no adverse influence to the soft capsule, rather than to serve merely as a bulking filler and an excipient as conventionally known.

It should be also noted that the proportion of each 10 effective ingredient containing starting exudate material of Chlorella algae, fungi and tonic medicinal vegetable incorporated relative to the edible fatty oil is particulraly not limited and.can be properly selected depending upon the type of products.
