We Prototyped "Dried Nameko" Using Domestically Grown Nameko
Namekois a mushroom characterized by a distinctive sliminess and rich umami, widely enjoyed in miso soup, dressed dishes, and more. Drying concentrates the umami components and improves shelf life, so it can be used in a form suited to commercial and processing uses. A feature is that the texture and flavor of nameko remain firmly even after rehydration.

In this prototype, we carefully dried domestic nameko as the raw material at low temperature and finished it additive-free and without coloring. It can be used for diverse product development such as soups, retort foods, dashi raw material, and health foods.
At Agriture, we conduct OEM development and provide commercial raw materials centered on domestic mushrooms. If you are considering product-making that makes the most of natural umami, please consult us.
Features of dried nameko and points to focus on regarding its components
Nameko (Pholiota microspora) is a mushroom of the Strophariaceae family, and its greatest feature is having a slimy component (viscous polysaccharides). Drying processing removes moisture and concentrates the umami, and the sliminess is restored when rehydrated in water. Dietary fiber, vitamin D, and niacin are points to focus on in terms of components, but because the content varies with cultivation conditions, we recommend confirming at the prototype stage. Nameko is familiar in Japanese miso soup and dressed dishes, but making it into a dried product widens shelf life and the range of uses. For detailed specifications,the product page for dried nameko.
Choosing between fresh nameko, boiled, and dried
Nameko differs in how the sliminess comes out and in its uses by processing form. Use the following comparison table as a guide for choices at the development stage (figures vary with cultivation conditions and processing methods).
| Item | Fresh nameko | Boiled (pouch, canned) | Dried nameko |
|---|---|---|---|
| Main use | Miso soup, dressed dishes, udon | Miso soup, hot pot | Dashi raw material, soup ingredient, or powdered into seasoning |
| Storage period guide | Refrigerated 3-5 days | Room temperature 6-6 months (from the shipping date) | About 6 months from the shipping date |
| Restoration of sliminess | As is | As is | Sliminess restored by rehydration |
| Concentration of umami | ★ | ★ | ★★★ (umami concentrated by drying) |
| Presence of additives | None | Citric acid, etc. (depends on the product) | Not used (Agriture specification) |
A distinctive point of dried nameko is that the slimy component is restored when rehydrated in water. This sliminess contributes to the mouthfeel of miso soup and the thickness of soups, and even the dried product gives a texture close to fresh nameko.
Variations of processing form
Agriture handles whole drying, cut drying, and powder processing. Whole drying suits soup and miso soup ingredients that make the most of the appearance, while powder suits dashi raw material and seasoning blends.
.
Dried nameko suits product development centered on the mouthfeel from the slimy component and the concentration of umami. Here we introduce representative ideas by application.
Miso soup and instant soup
The most representative use of dried nameko is as a miso soup ingredient. Adding dried nameko to freeze-dried miso soup or instant miso soup restores the sliminess when hot water is poured, finishing as an authentic nameko soup.

- Blend ingredient for cup soups and soup kits
- Ingredient for hot-pot sets (mushroom mix)
Dashi and seasonings
Powder-processed dried nameko is used as a raw material for mushroom-type dashi and in seasoning blends, allowing the design of natural dashi with layered umami.The nutritional value and benefits of vegetable powder.

- Mushroom-flavored powdered seasonings and furikake
- Umami-reinforcing ingredient for reduced-salt dashi
Dressed dishes, tsukudani, and prepared foods
There is also a way of using dried nameko rehydrated in water as an ingredient for dressed dishes and tsukudani. Being able to use nameko of stable quality year-round in seasons and regions where fresh nameko is hard to obtain is a commercial advantage.List of dried-vegetable productsYou can also check other dried mushroom products at .

Because the degree to which the sliminess is restored and the texture change with cut size and drying conditions for dried nameko, we recommend a process of confirming the target finish at the prototype stage.
- dried vegetable / powder OEM inquiry formContact us with the prototyping content, application, and desired form via
- Share the envisioned product and target texture in a concept hearing (Zoom or email)
- Ship a prototype sample per 1 kg of raw material (usually 2-3 weeks). Comparison prototyping with different cut sizes is possible
- Contact us with the prototyping content, desired shape, and assumed application via

Frequently asked questions
Q. Does the sliminess of dried nameko come back?
A. When rehydrated in water, the slimy component is restored, giving a mouthfeel close to fresh nameko. The thickness when added to miso soup or soup is still present in the dried product. Since the slimy texture is harder to feel when made into powder, cut or whole drying is recommended if you want to make the most of the mouthfeel.
Q. Can it be used as an ingredient for instant miso soup?
A. Cut dried nameko has a prototyping track record as an ingredient for instant miso soup. When hot water is poured, it rehydrates in a short time and the sliminess emerges, finishing as an authentic nameko soup.
Q. Can it be blended with other mushroom or vegetable powders?
A. Yes. With other dried mushroom products such as enoki, shiitake, and maitake, and.Vegetable powder list pagePlease check the items on
Q. Can you issue a certificate of raw material origin and an analysis table?
A. We can issue both a certificate of raw-material origin showing it is a domestic raw material and a microbial test report.
Q. Can it be blended with other dried vegetables?
A. Prototyping is possible from 1 kg on a raw-material basis. You can compare whole, cut, and powder forms at the same time, and main production is from 10 kg of raw material as a guide.
