The Chinese invented the marker determining the suitability of products

Spoiled food – it is a serious problem, which can not only undermine human health, but also will turn even fatal. To avoid such a disaster, there is just one single way to be saved – closely monitor the shelf life of food in the refrigerator. But man is not a computer, he is mistaken, and the products have a bad habit of spoiling the most inopportune moment. This problem by using science and try to solve the Chinese researchers from Beijing University. The result of nearly three years of work was “something” called Tiny gel tags.

Tiny gel tags – an organic marker (namely organic) which is able to respond to the environment. Under the influence of light, humidity, air temperature, Tiny gel tags behaves exactly like most perishable foods – it will spoil. Only spoils the invention of Chinese scientists is very conditional. Having a green color, Tiny gel tags gradually changing it to red, thus informing the degree of “tuhlosti” product: green – fit, yellow – suspicious, red – spoiled. There is still black – indicating that most likely the product is nothing left.

Needless to score, which gives Tiny gel tags – relative, because the marker to its “conclusions” based only on those chemical reactions that occur within it under the influence of natural factors. To date, there are already four classes marker Tiny gel tags.

First – for dolgohranyaschihsya products, the second – for products with a shelf life of harmful, the third – and fourth for perishable products for which can deteriorate for several days. Tiny gel tags now being verified, including the safety and, if successful, Chinese scientists announced their intention to seek a sponsor for the production of their invention on an industrial scale.
