By using the above Seviolite as a carrier, the peptide-containing substance immobilized product of the present invention can be obtained. On this occasion,
After being shaped into a desired shape such as a granule or a film by Seviolite, it is used for immobilization of a peptide-containing substance. In this case, sepiolite can be physically shaped and used as a carrier for immobilization, but it is usually preferable to use one that has been sufficiently dried by heating. In particular, it is preferable to use a carrier from which adsorbed water and water of crystallization have been sufficiently removed by heating, since this improves the brittleness of the resulting carrier and thus the immobilized product, thereby making it possible to obtain a practical immobilized product. Such heat treatment is usually suitably carried out at a temperature of 450 to 550°C. At temperatures below 450°C, sufficient drying (dehydration) cannot be achieved even if heat treatment is performed for a long time;
If the temperature exceeds .degree. C., the amount of hydroxyl groups present in Seviolite will be reduced, so it is not suitable. Usually 450-55
It is most preferable to carry out the reaction at 0° C. for about 3 to 4 hours. Note that by adjusting the temperature and time of such heat treatment, the hardness of the carrier can be appropriately set depending on the molding and use. Sufficiently dried sepiolite can be easily crushed and granulated, and is the most preferred carrier for obtaining particulate immobilized products.

It is usually suitable to immobilize a peptide-containing substance onto such sepiolite using a coupling agent. For example, when immobilizing enzymes, silane coupling agents [e.g., r-aminopropyltriethoxy 7y
It is preferable to use Sr-chloropyltrimethoxysilane, vinyltriethoxysilane, r-glycidoxyglobiltrimethoxysilane, N-β-(aminoethyl)-1-aminopropyltrimethoxysilane, etc. ,
Preferably, γ-aminopropyltriethoxysilane is used. For immobilization using these, for example, sepiolite is added to these aqueous solutions or kept in contact with them, the silane coupling agent is introduced by reacting with the hydroxyl group in sepiolite, and then a bifunctional immobilization agent (for example, After treatment with an aqueous solution of glutaraldehyde, etc.), the enzyme is immobilized by chemical bonding with the silane coupling agent residue in Seviolite by contacting with an aqueous solution of the desired enzyme. However, in some cases, it is also possible to directly immobilize without using a coupling agent, such as in the so-called cyanogen bromide activation method.

The peptide-containing substance immobilized product obtained by K in this way is
This activity is due to the abundant hydroxyl groups of sepiolite and its large specific surface area (230 to 26 G'/,
) K-dipeptide-containing compounds have good Mg effect and are thought to be able to produce T-electrification with a strong Bi-tsuta aroma. This is thought to be due to the fact that the immobilization and the action of the immobilized substance on the substrate etc. are carried out efficiently.
