The website of the American Chemical Society recently reported a fast -checking system for processing meat. Using test strips and mobile phone apps can quickly determine the nitrite content of carcinogens in sausages, ham, bacon and other foods.

Nitrite is a kind of preservatives commonly used in processed meat that can extend the shelf life and prevent Salmonella, Liszer or Botox, and can also bring attractive color and fragrance to meat. However, it may be converted into nitrosamine in high temperature cooking or acidic environment in the body, which is a first -class carcinogen. A study involving 100,000 people found that eating nitrite often increased the risk of breast cancer by nearly 25%, and the risk of prostate cancer increased by nearly 60%.

The European Food Safety Administration stipulates that the daily intake of nitrite should be controlled below 0.07 mg per kilogram. How do we know how many nitrite of the processing meat we buy and is the merchant over -added? The equipment in the professional laboratory is too complicated, and a fast inspection suitable for ordinary residents may help.

Spanish scientists designed a "POLYSEN" color -changing film. This is a thin film made of 4 monomers and hydrochloric acid. It is posted on the processing meat for 15 minutes to respond to nitrite. color.

Let's take a brief look at the process of chemical reactions. Nitro -yang ions in foods can generate a series of reactions with the indicator to generate even nitrogen compounds, resulting in color rendering.

The darker the color, the more nitrite the nitrite. With the mobile phone APP combined with the previous calibration data set, you can evaluate a new product range of nitrite content, which provides important reference for purchasing and cooking. Try to eat too little or not.
