The relative color of the oxygen indicator

1236348 V. Description of Invention (23) is CS21-04. When the product was stored in a thermostat at 5 ° C, the oxygen concentration in the bag dropped to 0.02% the next day, and the hue of the oxygen indicator became CS26-04. Then, the bag was pushed out of the pinhole with a sewing needle, and the oxygen concentration in the bag was measured the next day, and it was found that it rose to 0.4%. At this time, the color of the indicator changes to CS24-04, indicating that there is a problem with the sealing bag. After two more days, the oxygen concentration in the bag increased to 12%, and the hue of the indicator changed accordingly to CS22-04. To measure the oxygen concentration in the bag, take out a small amount of gas from the sealed bag and analyze it with a gas chromatograph. It is thus known that when an accident occurs in a food packaging container provided with a deoxidizer, which hinders its ability to remove oxygen, the viscous oxygen indicator of the present invention can correctly reflect the existing conditions and change its hue. The viscous oxygen indicator of the present invention has a simple structure, and thus can be produced in a cheap manner. In addition, because the product can have the same thin tape shape as a general single-sided self-adhesive tape, it can be used after cutting the indicator to an arbitrary length with a simple tool. Furthermore, the indicator can be manufactured, cut, and pasted automatically using a mechanical device, and is very easy to use. Another feature is that the indicator changes its color fairly quickly in response to changes in oxygen concentration, which helps monitor this concentration with the naked eye. This indicator will not show abnormal color tone in highly humid or greasy environment, and can be safely used in packaging with deoxidizer; quality control of the product, when adhered to the deoxidizer package or inside the packaging container for storage In addition, its hue or discoloration rate does not deteriorate, and it can provide excellent performance as an oxygen indicator. The product's ability to indicate oxygen concentration by hue and maintain excellent rate and hue stability can also be applied to remove oxygen packaging
