The British “New Regal Technology†company has developed a color change label that can show the freshness of food. According to the company, this product is called the Novas inlay label, which is discolored when exposed to external influences such as oxygen, ultraviolet rays and humidity, which can significantly improve food safety. The product is expected to be available early next year.
According to foreign media reports, a British company recently announced the development of a color-changing label that can show the freshness of foods. The product is expected to be available early next year and will be sold first in supermarkets in the United Kingdom.
This latest high-tech product was launched by the British company "Insignia Technologies". According to the company, this product is called the Novas inlay label, which is discolored when exposed to external influences such as oxygen, ultraviolet rays and humidity, which can significantly improve food safety. When the consumer opens the package, the Novas embedded tag is incorporated into the film lid and activated, and the timer then undergoes a strong color change as the freshness of the food in the package is lost.
It is understood that this label is mainly applied to frozen meat and cheese products, but as the market's demand for modified atmosphere packaging increases, discoloration labels will gradually apply to any food that produces carbon dioxide. The initial color of the label is light yellow and becomes dark purple when activated by carbon dioxide. Insignia Technologies is currently investigating changes between the two colors to ensure that the color changes are clearly visible after they are introduced to the market.
