Introducing Our Oxygen Absorbers
We manufacture our products that preserve food freshness in a factory equipped with a highly hygienic clean room to deliver food safety and security.
What is WonderKeep®, an oxygen absorber?
WonderKeep® extracts oxygen from the interior of a sealed package and the atmospheric oxygen level drops to less than 0.1%.
- It preserves the freshness, flavor, and nutrition of foods.
- It prevents food deterioration and color fading, protecting its flavor and color.
- It has a wide range of applications other than food; it stops metal objects from rusting, keeps insects away from stored clothing, etc.
What is WonderSensor®, an oxygen sensor?
- WonderSensor® detects oxygen in a food package, indicating the presence of oxygen by turning from pink to blue.
What is SensorKeep?
- SensorKeep combines the benefits of WonderSensor® and WonderKeep® in one convenient package.
- One convenient package eliminates the extra processing step of putting WonderSensor® in the food package with WonderKeep®.
- SensorKeep allows confirmation that a package is completely sealed to assure the safety of food at a glance.
Additional Advantages
- A vastly extended shelf life can broaden the range of marketing possibilities.
- New additive-free food products can be developed more easily.
- Production and inventory adjustments are simplified.
- Food freshness is preserved and food loss is reduced.
