New Smartphone App Finds Cancer-Causing Food Additives
By Simona KitanovskaA new smartphone app is able to check food for cancer-causing chemicals. Scientists have developed a color-changing film that shoppers can stick onto processed meats. When nitrite was present, the film’s yellowish hue deepened with higher nitrite levels in the food. To quantify the color change, the researchers created a smartphone app that self-calibrates when a chart of reference disks is photographed in the same image. The team tested the film on meats they prepared and treated with nitrite, in addition to store-bought meats.
