Of these, about 130,000 tons of caffeine-containing food waste such as coffee grounds is said to have been disposed, and about 60% of these wastes have been disposed of by contractors (Coffee Market, Teijin Foods Newspaper). , September 5, 1993).

Cover with a vinyl sheet or the like and leave it for 3 to 5 months, compost it using microorganisms and make it into a special fertilizer. Since it is effective to prevent the generation of offensive odors when it is mixed with cow dung and made into fully matured compost, it is composted with livestock dung by mixing it with rice straw, peach, etc. (Monthly Food Chemical, No. 9,

I thought about using waste. In this case, the problem of caffeine contained in the waste must be solved. Caffeine has selective toxicity, and at a concentration of 1600 ppm, it does not inhibit the germination and growth of leguminous plants (Ketuzu adzuki, rape), but plants other than leguminous plants (haribiyu, cedar,

である。The persimmon astringent used in the present invention refers to a liquid obtained by fermenting and filtering a juice squeezed from a young fruit of the persimmon persimmon. In the present invention, persimmon astringent extract cake discarded during the production of the persimmon astringent is also included. Persimmon astringent is also called persimmon tannin or persimmon extract, and its main component is condensed tannin. Persimmon astringent extract lees also contain a few percent of the same condensed tannin. The condensed tannin of Kakishibu has the property of aggregating with proteins and alkaloids at room temperature by strong binding, and is composed of a high molecular weight polyphenol that does not inhibit plant growth. The sake industry uses the properties of persimmon astringent to reduce the protein content of sake, but the fertilizer method of the present invention also utilizes this unique property.

For example, coffee grounds, tea (hikicha, gyokuro, sencha, Bancha, oolong tea, black tea, dancha, etc.), extracted cake of caller fruits, extracted cake of cacao seeds and the like.

ことができる。The method of contacting persimmon astringent with caffeine-containing food industrial waste in the method of fertilizer of the present invention is not particularly limited. For example, caffeine-containing food industrial waste is washed by persimmon astringent washing of caffeine-containing food industrial waste. It can be carried out by directly mixing persimmon astringent with the product, or by mixing caffeine-containing food industrial waste with soil to which persimmon astringent is added. The caffeine coagulated sediment combined with persimmon astringent and the caffeine-containing food waste reduced in caffeine by persimmon astringent obtained by the contact can be effectively used as a plant growth promoting substance and a fertilizer, respectively.

It can be used in a proportion of 100 ml, preferably 20 to 50 ml. If the amount of persimmon astringent is less than the above range, the effect of reducing the caffeine concentration will be poor, and if it exceeds the above range, even if a large amount of caffeine can be removed, it will be costly and unfavorable.

とが可能である。The present inventors have found that, as a result of fractionating persimmon astringent, various persimmon astringents have a high binding ability to caffeine (aggregate sedimentation) and a fraction that does not bind at all. It is also known that persimmon juice removes not only caffeine but also other alkaloids and proteins that affect the growth of plants. This is because the binding abilities of the persimmon astringent polyphenols are different since they have a wide molecular weight distribution. By utilizing such properties of persimmon astringency, it is possible to efficiently remove a desired plant growth inhibitor.

was added and the mixture was boiled for 30 minutes to completely extract caffeine, and then 50 ml of persimmon juice was added. The resulting aggregated precipitate was filtered and washed with water to obtain a persimmon juice-coffee cake precipitate. In order to confirm the plant growth promoting effect of the persimmon astringent-coffee cake precipitate, the growth conditions of radish and spinach in the following sections (a) to (c) were compared. The growth condition was determined by taking the weight after plant growth as the average value of the number of individuals (however, (a) the average value of the control group was converted to 100). (A) a section of soil only without using coffee grounds (control) (b) a section in which persimmon astringent untreated coffee grounds was added at a ratio of 4: 1 to the soil (c) the above-mentioned persimmon astringent-coffee ground precipitate was added to the soil Addition area (soil and persimmon astringent-coffee lees used in the production of coffee lees precipitate at a ratio of 4: 1)

Thus, using commercially available caffeine, a persimmon astringent-caffeine precipitate had the same effect. We examined whether or not. 1 liter of 1% w / v caffeine aqueous solution
Was added, and 50 ml of persimmon astringent was added thereto. The resulting aggregated precipitate was filtered and washed with water to obtain a persimmon astringent-caffeine precipitate.

として利用することができる。As described in detail above, according to the fertilizer method of the present invention, the plant growth inhibitory substances such as caffeine can be aggregated and reduced by the treatment with persimmon astringent. The food industry waste containing the substance can be fertilized at an early stage. In addition, the coagulated sediment of persimmon astringent and caffeine obtained by the fertilizer method of the present invention has an excellent plant growth promoting effect, and can be effectively used as a plant growth promoting substance. In addition, caffeine-containing food industry waste in which caffeine has been reduced by the fertilizer method of the present invention does not inhibit plant growth, and can be effectively used as a fertilizer.
