WonderKeep®
Pioneered from iron powder production technology, WonderKeep® preserves the freshness, flavor, and nutrition of foods by eliminating oxygen in packaging.
WonderSensor® Oxygen Detector
WonderSensor® Oxygen Detector
WonderSensor® is a revolutionary product that detects oxygen content in packaging, providing information to ensure optimum freshness in a wide spectrum of food products.
WonderSensor® detects oxygen over 0.5% by turning blue. When WonderSensor® is put in an environment with oxygen of less than 0.1% content WonderSensor®’s color becomes pink. One of WonderSensor®’s outstanding features is a paper type indicator which is the first of its kind in the entire industry and fits in the food package better than a tablet type indicator.
WonderKeep® and WonderSensor® can be combined together, eliminating an extra processing step of putting WonderSensor® in the food package with WonderKeep®.
How WonderSensor® Works
WonderSensor® is used to indicate if oxygen is present in the ambient air inside the food package.
With WonderKeep® and WonderSensor® in the same container, it is possible to detect the presence of oxygen in the container by a change of color.
The color will be blue for oxygenic conditions (oxygen above 0.5%) and pink for anoxic conditions (oxygen below 0.1%).
Note: The colors presented here are examples and the actual colors may vary depending on the ambient environment. The shade of colors between blue and pink varies according to the oxygen content.
How to Use WonderSensor®
Use WonderSensor® to check for a defective package: Place WonderSensor® and WonderKeep® together inside the package to check that there are no pinholes or if the package has sufficient barrier performance against oxygen permeation.
