Supporting crew health and enjoyment of food
On long voyages at sea, meals are one of the few pleasures for crew members and also play an essential role in maintaining their health.
However, during extended ocean crossings, it is difficult to store fresh produce like vegetables and fruits. As the voyage progresses, meals tend to rely more on frozen or processed foods.
This often results in limited variety and unbalanced nutrition.
DENBA+ Marine, a freshness preservation system for ships, is designed to solve these issues.
It allows fresh ingredients to stay preserved for longer periods even on board, enabling diverse and nutritious meals at sea and supporting both the health and satisfaction of the crew.
DENBA+ Marine is also effective for maintaining freshness during maritime transport and plays a key role in building the next-generation cold chain in food logistics.
