Description of Prior Art It is well known that Chlorella is one of the single cell algae which grow in fresh water. It contains protein in a large amount, has an effect of promoting the growth of animals or microorganisms, an effect of flavouring foods, and an effect of removing foreign odor from foods. In particular, a hot waterextracts of Chlorella algae have a wide range of applications, because they have S such growth promoting and flavouring effects and because they are liquid.

Various products utilizing Chlorella algae have been conventionally developed in view of the usefulness of such Chlorella algae. Typical of them are Sproducts made by blending a dry powder of Chlorella algae with a garlic powder and molding the blend into a tablet, noodles and processed marine procuts S, containing a hot water-extract of Chlorella algae used as a flavouring component and a quality improving agent during production thereof, i i la and health food products made by incorporating a dry powder or hot water--extract of Chlorella algae into vegetable edible fatty oils and encapsulating the resulting material into a gelatin capsule. Thus, such products utilizing Chlorella algae find applicatons covering a wide range.

As described above, various Chlorella products have been conventionally developed in view of effective ingredients of Chlorella algae. In many cases, however, the prior art Chlorella products have considerations in o" processing operations in the course of production thereof and o co suffer from a disadvantage that the effective ingredients 09 6 of Chlorella algae are not necessarily retained in a stable manner. More specifically, in spite of the usefullness of Chlorella algae having been ascertained at the stage of tests and research there is a problem that when the effective ingredients are utilized to provide a product, it is difficu' to retain the effective ingredients in Sa stable manner. Especially, in making a health food product using Chlorella algae in combination with other medicinal starting materials, it is important to stably S and effectively retain medicinal ingredients of individual starting materials, but the prior art products suffer from a problem that the medicinal ingredients may be stably and effectively not retained in many cases.

Summary of the Invention Thereupon, the present inventors have made zealous -2r- -I studies to develop a health product using Chlorella algae in which effective ingredients of Chlorella algae and other medicinal starting materials are stably retained as they are, .and consequently, have found that intended objects can be achieved by using a dry powder of a clathrate blend resulting from the addition of a concentrated exudate of a hot water-extract of Chlorella algae to a clathration material, followed by blending S and drying of them, and a dry powder of clathrate S blend resulting from the addition of a concentrated exudate of a hot water-extract of fungi to a clathration Smaterial, followed by blending and drying of them, and further by addition of the dry powder to an edible fatty oil or oils, followed. by homogeneously dispersing or mixing and encapsulation into a soft capsule. Thus, the pr'-ent invention has been accomplished.

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

It is another object of the present invention to provide a Chlorella--containing fatty oil foodstuff which containes edible fatty oil in a large amount and even effective ingredients of Chlorella algae, fungi and tonic medicinal vegetables in a stable manner.

It is -a further object of the present invention 3 1 to provide a Chlorella-containing fatty oil foodstuff capable of being also used as a cooking product.

To achieve the above objects, according to the present invention, there are provided: 1) A process for producing a Chlorella-containing -fo .l o'l foodstuff, comprising the steps of homogeneously mixing i a dry powder of a clathrate blend resulting from addition of a concentrated exudate of a hot water-extract of Chlorella algae to a clathration material, followed by S-I blending and drying of them, and a dry powder of clathrate blend resulting from the addition of a concentrated exudate of a hot water-extract of fungi to a clathration material, followed by blending and drying of them, and an exudate or dry powder of tonic medicinal vegetable, with an edible i fatty oil which may contain a lecithin, i vitaminE awd ti the l-ke optionally- added thereto, and encapsulating the resulting oil-suspension into a soft capsule.

2) A process for producing a Chlorella-containing j foodstuff according to the above item wherein the clathration material used is a cyclodextrin.

3) A process for producing a Chlorella-containing foodstuff according to the above item wherein the S^ fungus used is at least one of kawaratake, polypore, and shiitake.

A process for producing a Chlorella--containing foodstuff according to the above item wherein the blending is carried out under a humidified and depressurized condition.

6) A process for producing a Chlorella-containing foodstuff according to the above item wherein the edible fatty oil used is at least one of peanut oil, sesame oil, wheat germ oil, rapeseed oil, soybean oil, coconut oil, safflower oil, and beeswax.

7) A Chlorella-containing foodstuff which is produced S "by homogeneously mixing a dry powder of a clathrate blend resulting from addition of .a concentrated exudate of a hot water-extract of Chlorella algae to a clathration I material, followed by blending and drying of them, and a dry powder of clathrate blend resulting from addition of concentrated exudate of a hot water--extract of fungi to a clathration material, followed by blending and drying of them, and an exudate or dry powder of tonic medicinal vegetable, with an edible fatty oil which may contain or a lecithine, vitamin E and th e- e- optionaly added thereto, and encapsulating the resulting oily suspension into a soft capsule.

The process for producing a Chlorella-containing fatty oil foodstuff according to the present invention has an advantage that it is capable of producing a A0 5 product containing effective ingredients of Chlorella algae, fungi and tonic medicinal vegetables stably retained therein and having an excellent preserveability of each effective ingredient. Further, the product of the present invention has an unexpected effect that the soft capsule does not swell, even if it contains an exudate of a tonic medicinal vegetable having a relatively large content of moisture, because it contains a large amount of an edible fatty oil having a cholesterol reducing effect and each of the ingredients is homogeneouly dispersed.

o a o" The Chlorella-containing fatty oil foodstuff of the s o present invention can be eaten by itself not only as 0 a health food, but also utilized as a cooking material for oily foods such as vegetable frices. Further, it can be utilized for camping or the like, because of U its portability.

o 4e Especially, the Chlorella-containing fatty oil foodstuff of the present invention has the advantage of an unexpected effect which is not possessed by the prior art product, in that the effective ingredients of Chlorella algae 0 900 and fungi can be stably and effectively preserved over a long period.

Detailed Description of the Ienvention In the present invention, an edible fatty oil is used in a relatively large amount with respect to a concentrated exudate of a hot water-extract of Chlorella -6algae, a concentrated exudate of a hot water-extract of fungi or an exudate or dry powder of tonic medicinal vegetables, in order that the soft capsule is prevented from being subjected to any changing such as swelling and/or dissolution thereof by moisture present in effective ingredients containing materials such as the Chlorella algae, fungi and tonic medicinal vegetables. The product can be used for cooking and particularly for Sfrying. In addition, the homogeneous mixing of the i effective ingredient containing materials into the edible i fatty oil is to prevent the soft capsule from being swollen and broken.

i In the present invention, the hot water-extract i of the Chlorella algae may. by an extract produced by I subjecting a aqueous suspension of fresh Chlorella algae from an open-air mass cultivation by an optical synthesis to a heating treatment at a temperature of about to 100 'C for 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 "t pyrenoidosa, Chlorella vulgaris, Chlorella ellipsodea, Senedesmus. The hot water-extract of Chlorellaalgae contains effective polysaccharides such as N 3 glucan and acidic rhamnan. 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 -7- S such powder and treatment at a t, i one hour or more treatment, and. su: i 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 suitable hot water -extract such as produced by adding and mixing water to fungus body powder in an amount of four times as much as such powder and subjecting the mixture to a heating treatment at a temperature of 45 to 120'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 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 form of 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 from grinding in a colloid mill, and the word "dry powder" referrs to those resulting from a proper pretreatment of vegetables, followed by a hot air drying, a freeze -8drying 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 slurry-like concentrated exudate in a concentrator, and each of the exudates are then blended in a blender together with a clathration material to form a ij clathrate blend. It is preferred that the clathrate blend is used in a pulverized form obtained by drying in a dryer to the extent of a defined moisture 1| content, followed by pulverization.

It is also preferred that the tonic medicinal vegetable is used in the form of a slurry-like VI exudate resulting from grinding each vegetable or its exudate powder in the presence or absence of vitamin E oil in a colloid mill.

The edible oils which may by 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, it is preferred that they are used in the form of an oil emulsified material produced by heating the mixed 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.

9 To homogeneously mix the effective ingredient containing materials of Chlorella algae, fungi and tonic medicinal vegetables with the edible fatty oil, each of the dry powder of the above-described clathrate blend, the exudate or dry powder of the tonic medicinal vegetable, and the edible fatty oil, may be homogeneously stirred and mixed in a mixer. The sequence of individual starting components mixed is not essential but when the effective ingredient containing material of the tonic medicinal vegetable is an exudate, it is i preferred that the exudate is homogeneously mixed to *the edible fatty oil and then, each of the dry powder i of the clathrate blend is homogeneously mixed to the resulting suspension in the oil. On the other hand, when the effective ingredient containing material of i the tonic medicinal vegetable is a dry powder, it is i preferred that the dry powder is mixed with each of the dry powder of the clathrate blend and then, the resulting mixture is homogeneously mixed to the edible fatty oil.

SThus-obtained starting mixture is then passed through a proper mesh strainer and degassed in a deaerator, following which the resulting mixture is encapsulated into a soft capsule such as a soft gelatin capsule.

When the exudate of the tonic medicinal vegetable is a leached liquid, it can be also used as a spray-dried material, but this is expensive, because water is present in too a large an amount in the leached liquid. Therefore it is preferred that with or without dry .powders of Chlorella algae and /or tonic medicinal vegetable added, the leached liquid is adsorbed to an edible powder such as lactose, starch or the like and the resulting material is powdered. The edible Spowder such as lactose, starch or the like is properly Sused 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 4 an excipient as in the prior art.

It should be noted that the proportion of each effective ingredient containi.ng material of Chlorella i{ algae, fungi and tonic medicinal vegetable incorporated relative to the edible L...ty oil is particulraly not I limited.

I The present invention will now be described in more detail by way of Examples.

Example 1 Water 300 1 was mixed with an optical synthesized t Chlorella powder 30 kg, and the mixture was subjected SA to an extraction of effective ingredients in a hot water extractor.
