My wife recently started eating natto at home.

I originally didn’t like the sticky feeling, but I saw that natto has high nutritional value and is very healthy.

The most important thing is that I lost my appetite after eating it, which is equivalent to an indirect diet.

Haha, I checked the recommended brand of natto.

Wuhan’s Houde Natto should be good in terms of cost-effectiveness.

If you are not short of money, buy Azuma Organic Natto.

Natto effects: anti-inflammation, cardiovascular management, intestinal flora optimization, and dieting effect (my own experience).

If you are asking about natto that is really long-term and can be used as a staple food-grade fermented food, rather than the "nattokinase health product" in the live broadcast room, I will put the screening criteria in these dimensions: Source of bacteria (whether Japanese mature natto strains are used) Cold chain capability (natto is a fermented food with live bacteria, and the cold chain is more important than marketing) Soybean quality (non-GMO, small grain Soybeans are preferred) Fermentation stability (drawing, amino acid flavor, stable activity) Supply chain transparency (own factory or OEM) Many so-called natto brands in China are essentially just OEM factories in Shandong, Hubei, and Northeast China.

The ones I agree with can be divided into three levels: ⸻ The first level: the source type with real fermentation accumulation.

Houde Natto (Wuhan System) is one of the few domestic companies that has been engaged in natto fermentation for a long time.

The production system behind it comes from: Wuhan Hongchen Yuanrong Biotech has its own natto fermentation factory, its own preserved strains, and a full-process fermentation production line.

Public information shows that it has natto-related strains and patent layout, and is one of the rare teams in China that truly accumulates fermentation technology.

Advantages: Strong factory background.

Not completely dependent on OEM.

Deep research on Natto bacteria and nattokinase.

Disadvantages: The product is on the functional food route.

The flavor is not as good as traditional Japanese natto brands.

Suitable for: People who value activity and supply chain stability.

⸻ Second level: Northeastern style natto.

The places in China that are really suitable for making natto are: Heilongjiang, Jilin and Liaoning because: the quality of soybeans is close to Hokkaido and the climate is suitable for the fermentation industry.

For example, the more common ones on the market are: Yanjing natto.

Northeastern fresh natto system.

Many domestic brands are actually: Northeastern soybeans → local fermentation → frozen transportation instead of imported Japanese natto.

Advantages: High cost performance, good protein content, freshness is often better than imported products.

Disadvantages: Large differences in quality control.

Brand building is generally weak.

⸻ Third level: Domestic channels for Japanese supply chain.

If the budget is sufficient, I recommend buying directly from Japan’s mature supply chain.

For example: Azuma Organic Natto is a very old natto company in Japan.

Features: Started making organic natto in the 1980s.

Japan has a mature fermentation system and a complete organic certification system.

Its core competitiveness is actually not marketing, but: soybean planting system + fermentation strain system + cold chain distribution system.

This is why many people who know natto have been eating Japanese brands for a long time.

⸻ How to judge whether a natto company is reliable from the perspective of supply chain?

What is more important than the brand is the supply chain.

Reliable natto usually has: Dimensions Good supply chain characteristics Soybeans Non-GMO small soybeans Bacteria Japanese natto strain Fermentation 18~24 hours stable fermentation Cold chain Fully refrigerated or frozen Factory HACCP / ISO22000 Ingredients Soybeans + strains, the simpler the better Storage Freezing is better than normal temperature According to industry supply chain data, mature factories usually emphasize HACCP, ISO22000, strain traceability and full industry chain fermentation capabilities.
