DENBA Refrigeration

Maintaining food freshness

DENBA technology is an innovative next-generation freshness preservation system that activates water molecules within food to maintain its seasonal deliciousness without compromise.

By simply installing a compact device in your existing refrigerator or freezer, you can experience the freshness-preserving effects of DENBA. Even premium fruits like grapes and Shine Muscat retain their juiciness for up to two months. In meat processing plants supplying supermarkets, drip loss during thawing of meat and fish has been reduced by up to 95%. Ordinary freezers can now freeze without damaging cells, and DENBA has been adopted in household refrigerators, commercial units, transport trucks, and containers worldwide.

In recent years, the food and distribution industries have been greatly affected by climate change due to global warming, natural disasters such as typhoons and heavy rains, and the unpredictability and decline in customer traffic caused by the COVID-19 pandemic.

In addition, globally, companies are being called upon to take active steps toward achieving the SDGs (Sustainable Development Goals).

To producers, retailers, the food service industry, and those involved in food distribution, we propose DENBA products that can help address issues such as adjusting shipping timing to enhance product value, stabilizing prices by reducing market oversupply, expanding sales channels, extending freshness periods to maintain pricing, and reducing food waste.

Concerns Faced by Business Operators

The food and beverage industry has been heavily affected by the spread of COVID-19.

Since the pandemic began, many inquiries have come from restaurants facing issues such as an increase in food waste or a decline in quality when freezing surplus products, due to a drop in customer traffic and the inability to sell at the same pace as before.

To address these challenges, we offer support through technologies such as freshness preservation, high-quality freezing, and thawing that minimizes drip loss.

If you are facing similar issues, please feel free to consult with us.

Key Features of DENBA+

DENBA+ creates a chilled environment where water molecules do not freeze even between 0°C and minus 4°C, by generating an ultra-low-frequency electromagnetic field inside the refrigerator using proprietary technology. The interior is influenced by electrostatic waves, which suppress oxidation of food and also provide antibacterial effects. This technology enables DENBA+ to maintain freshness while also offering an ideal environment for aging food.

Point 1: Does not freeze even below zero

By creating an electrostatic wave environment inside the unit, it allows a chilled condition where food does not freeze even at minus 4°C.
Food can be stored fresh for a longer period.

Effect

Because it does not freeze, food continues to age and develops deeper flavor.

Bacterial growth is also suppressed, with occurrence reduced to about one-thirtieth compared to standard refrigerators (based on tests by the Japan Food Research Laboratories).

Point 2: Suppresses oxidation to maintain freshness

By generating electronic energy in the space and promoting redox reactions, it suppresses the oxidation of ingredients and keeps them in a fresh state.

Effect

Food cells become more active, helping maintain freshness for a longer time.

Point 3: Suppresses bacterial growth

After two weeks of refrigerated storage, beef stored in a regular refrigerator shows widespread discoloration in both fat and lean areas, along with a foul odor. In contrast, beef stored with DENBA shows no discoloration and retains clear freshness.

Summary of Effects and Features

① Prevents drip loss and promotes aging that enhances flavor

The chilled environment suppresses the outflow of drip and promotes the natural aging of food (increase in amino acids), leading to deeper, richer flavor. It is also highly effective in meeting the need to bring out more sweetness in fruits.

② Reduces deterioration after thawing

Even after thawing, food can be stored again with minimal shrinkage or softening. There is also little to no color transfer or unpleasant odor.

③ Odors do not transfer easily, allowing various foods to be stored together

Even when different types of ingredients are stored together in the same compartment, odors rarely transfer. This makes it ideal for storing multiple items at once.

④ Maintains the natural color of ingredients for longer

The redox effect that suppresses oxidation prevents discoloration caused by oxidation and helps retain the natural color of the food.

⑤ Maintains appearance and freshness of plated dishes

Even when sashimi or sliced meat is pre-cut and plated for storage, it retains its moisture and sheen until served. It is resistant to drying, sticking, deformation, and discoloration, helping keep dishes visually appealing until the moment of service.
