lA- S. and used as a flavoring component and a quality improving agent during production thereof, and heath food products made by encapsulating a dry powder or hot waterextract of Chlorella algae together with other nutritious and medicinal ingredients into a gelatin capsule. Thus, the applications of such products utilizing Chlorella algae cover 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 require considerations in processing i 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 ascertained and reported as a result of intellectual examinations and research th- re 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 the product cannot be utilized reliably and effectively.

Especially, in making a health food product by utilizing Chlorella algae in combination with other medicinal starting 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 -2medicinal 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 retained and the usefulness thereof cannot be sufficiently utilized.

Summary of the Invention Thereupon, the present inventors have made zealous studies to aim at the development of a functional health product in which effective ingredients of Chlorella algae l a a and other medicinal starting materials are stably retained w without any reduction of the activity thereof, and ta W a consequently, have found that intended objects can be ahcieved by using a starting material, an exudate powder resulting from addition of a concentrated exudate of a hot water-extract of Chlorella algae toget.her with a clathration material, followed by clathration blending a and drying of them, an exudate powder resulting from addition of a concentrated exudate of a hot water-extract of fungi together with a clathration material, followed a. by clathration blending and drying of them, and a slur-y- S..like starting material resulting from grinding of tonic medicinal vegetables and Chlorella algae in the presence,6f a vitamin E, and further by addition of them to an edible fatty oil or oils which may contain lecithin added thereto if required, followed by homogeneously stirring -3r or mixing and encapsulation into a soft capsule. Thus, the present invention has been accomplished.

It is therefore an object of the present invention to provide a process for producing a functional Chlorella- S containing fatty oil foodstuff with effective ingredients of Chlorella algae, fungi and tonic medicinal vegetables effectively and stably retained therein.

It is another object of the present invention to provide a Chlorella-containing fatty oil foodstuff which is usefull as a health food product having a functionality Sand containing various physiologically active ingredients I in a large amount and even effective ingredients of Chlorella algae, fungi and tonic medicinal vegetables in an effective and stable manner.

Detailed Description of the lenvention In the present invention, an edible fatty oil is used in a relatively large amount with respect to strating materials, a concentrated exudate of a hot water-extract of Chlorella algae, a concentrated exudate -7of a hot water-extract of fungi or an exudate of tonic medicinal vegetables, in order that the soft capsule material is prevented from being subjected to any changing such as swelling and dissolution thereof by moisture I present in effectiveingredients containing exudates of the Chlorella algae, fungi and tonic medicinal vegetables..

The product can be used in various applications, such as for cooking and particularly as a flavoring element J for frying. In addition, the homogeneous mixing of the I effective ingredient containing materials into the edible fatty oil prevents the soft capsul6 from being swollen Ii and broken.

,In the present invention, the hot water-extract of I t f "the Chlorella algae may be an extract produced by I subjecting a aqueous suspension of fresh Chlorella algaes from an open-air mass cultivation by an optical *i I synthesis to a heating treatment at a teperature of fi about 80 to 100"C for a period of 15 to 20 minutes, followed by fractionation of the algae. Typical of the ii fresh Chlorella algae are single cell algae growing in Sfresh water such as Chlorella pyrenoidosa, Chlorella 11 Svulgaris, Chlorella ellipsoidea, scenedesmus, but it is 4, 4 1 not intended to be limited thereto. T'he hot water-extract of Chlorella algae contains various physiologically active substances, proteins and vitamins as well as effective poly-saccharides such as N 9-1, 3 glucan and acidic rhamnan present on cell walls. Alternatively, -8i i

CI

the hot water-extract of Chlorella algae may be an extract produced by gassing 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 120C for about one hour or more and then to a slowly extracting treatment, and, suitable hot waterextracts can be also used.

The hot water-extractof fungi may be a hot water extract of fungus body, dry fungi and fungus body S. powder. For example, use may be made of a suitable S*o hot water-extract such as produced by adding and mixing water to fungus body powder in an amount of four o"a times as much as such powder and subjecting the mixture 0 to a heating treatment at a temperature of 45 to 120 'C for a long period of time, preferable, for 5 to 7 hours.

The word "fungi or fungus" referres to a polypore, kawaratake, shiitake and other edible mushrooms.

The tonic medicinal vegetable used may be any of s medicinal vegetables which have a nutritive tonic effect, but especially preferred are garlic, genseng, aloe, ume (Japanese spicot), prickly shrub of the familly Aradiaceae, and adlay. The tonic medicinal vegetable may be used in the proper form of the vegetable itself, an exudate or dry powder. The word "exudate" refers to leached liquids resulting from leaching of the tonic medicinal vegetables by a usual method and slurry-like exudates resulting -9- -i

I

from grinding the concentrate thereof and vegetable itself in a colloid mill. The dry powder which may be us'id includes those resulting from a proper pretreatment of I 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 fungi is independently concentrated into a slurrylike concentrated exudate in a concentrator, and each of the exudates are independently then blended in a blender i together with a clathration material forming a clathrate compound, thereby forming a clathrate blend. It is S t o desired that the clathrate blend is used in a exudate 1 4 powdered form obtained by drying in a dryer to the extent of a defined moisture content, followed by pulverization.

j The tonic medicinal vegetable may be used as a j starting material in the form of a slurry-like exudate S' 1 resulting from grinding of each vegetable or its exudate powder together with Chlorella algae in the presence or absence of vitamin E oil in a colloid mill.

The edible oils which may be used include peanut oil, sesame oil, wheat germ oil, rapeseed oil, soybean oil, coconut oil, safflower oil, beeswax, and other edible fatty oils. These oils may be used alone or in combinations. When the edible oils are used in combination,

To homogeneously mix the effective ingredient-containing starting materials of Chlorella algae, fungi and tonic medicinal vegetables with the edible fatty oil, each of the starting exudate powder materials of the abovedescribed clathrate blend and the exudate or dry powder of the tonic medicinal vegetable may be homogeneously stirred and mixed with the edible fatty oil in a mixer. The means for and the sequence of mixing of individual starting components are not essential but in general, it is desired that the slurry-like starting material resulting from grindin, of the tonic medicinal vegetable and Chlorella algae is homogeneously mixed to the edible fatty oil in the presence of a vitamin E oil and then, each of the starting exudate powder materials of the clathrate blend are homogeneously mixed to the resulting suspension in the oil. The concurrent homogeneous mixing of 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 -11- Chlorella alga, the use of a vitamin E oil ensures that physiological activities of the vitamin E and various effective iiigredients of the tonic medicinal vegetables can be effectively and stably intensified and maintained.

The oil suspension obtained by mixing the various starting materials in this 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, S f I thereby providing an intended functional Chlorellacontaining fatty oil foodstuff.

't It should be noted that the leached liquid of the vegetable can be used for the starting tonic I* medicinal vegetable material in the form of a spraydried material, but 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.

-12- It should be also noted that the proportion of each effective ingredient containing starting exudate material of Chlorella algae, fungi and tonic medicinal vegetable incorporated .relative to the edible fatty oil is not essential and can be properly selected depending upon the type of products.
