Originally, DENBA technology was developed to maintain the freshness of food for a longer period. Human cells are each electrically charged, with the inside of the cell being "−" and the outside "＋," maintaining stability. This is called polarization.

Disruption of this cellular balance greatly affects freshness and physical condition, causing pain and other issues.

Each substance has its own specific wavelength (vibration).

DENBA technology provides a wavelength that causes the water molecules to vibrate finely, allowing them to continue to vibrate naturally and without strain.

By retrofitting existing refrigeration and freezing equipment with DENBA products, DENBA technology provides fine electron vibration to the water molecules in food ingredients, allowing them to be refrigerated, frozen, and stored while maintaining their freshness.

Activating the cells of the food ingredients helps to maintain their freshness, suppress bacterial growth, and significantly reduce waste.

In addition, this technology is applied to frying equipment and health devices that can be used on the body to improve physical condition, gaining support from medical professionals, health-conscious individuals, and professional athletes alike.

DENBA's Mechanism for Scientifically Suppressing Oxidation

— 3 Key Points —

DENBA's unique technology has succeeded in suppressing oxidation in the space, allowing freshness to be maintained for a longer period. It also leads to increased growth speed and higher yields.
Here are the three key points of DENBA's freshness preservation technology.

Generates wavelengths in all directions (360 degrees) to finely vibrate water molecules in the entire space

By providing a frequency wavelength that causes the water molecules to vibrate finely, the entire molecular cell vibrates. Since it affects the entire space, it is effective even if it is away from the mat.

Cells that are finely vibrating become activated through vibration

The wavelength causes the cells to vibrate, activating them. Additionally, vibrating cells generate heat energy, raising the temperature of the solid. *In the case of water, more intense vibration leads to boiling.

Suppresses oxidative bonding with cells by filling the space with electrons

Before oxygen atoms bond oxidatively with molecules or cells in the space, the filled electrons bond with the oxygen. This prevents oxidation.

It has been proven that DENBA affects everything in the space, extending the freshness of any food containing water.

DENBA is Active Throughout the Food Cold Chain

DENBA technology has various positive impacts on the cold chain in Japan and worldwide.
It can be utilized throughout the flow from producers to general consumers, significantly reducing food loss.

In a world where calls for environmental improvement are growing louder, DENBA holds infinite potential and is an essential technology for the future.

What is a Cold Chain?

A cold chain is a logistics system that keeps perishable foods at low temperatures throughout the production, transportation, and consumption process. This technology has made it possible to distribute fresh foods widely and store them for long periods.

DENBA's Role in the Cold Chain

Production + DENBA

Currently, the freshness of fresh produce declines rapidly after harvest, significantly impacting quality. By introducing DENBA technology, it is possible to maintain freshness for a long period, allowing for flexible shipment adjustments according to market demand and ultimately maximizing revenue.

Transportation + DENBA

Currently, food freshness declines easily during transportation due to temperature changes and the passage of time. By installing DENBA technology on transportation means, these issues can be resolved, allowing for the transportation of food to distant locations while maintaining freshness. This enables the provision of high-quality products to a broader market, expanding the market.

Processing + DENBA

In the current situation where the quality of processed foods heavily depends on the freshness of raw materials, introducing DENBA technology enables the preservation of raw materials' freshness. This improves the quality of processed foods, gaining consumer trust.

Storage + DENBA

Even in storage in refrigerators and freezers, the quality of food declines over time. By introducing DENBA's potential technology, the freshness of food in these storage environments is greatly improved. This technology significantly contributes to reducing food loss by minimizing quality deterioration during long-term storage.

Sales + DENBA

Currently, maintaining the freshness of food at stores is difficult, and food loss occurs easily. By introducing DENBA technology, the freshness of food lasts longer, extending the sales period. This not only is expected to increase sales but also allows for the provision of fresher food to consumers, leading to improved customer satisfaction.

As mentioned above, by introducing DENBA technology, the freshness of food is greatly improved at each stage from production to transportation, processing, sales, and storage. This enables flexible shipment adjustments, market expansion through quality maintenance, consumer trust acquisition, and food loss reduction, ultimately realizing overall revenue enhancement through DENBA's introduction.
These benefits ultimately contribute to environmental improvement and lead to the trust and development of the overall food industry, making it a product with infinite possibilities.
