Researchers use strip of fabric to find the freshness of oranges
The study showed the coated fabric can soak up the chemical compounds in the juice of an orange to show the ripeness – or freshness – of the fruit.
Scientists at Florida International University (FIU), Miami, Fla., found a quick and reliable way to test the freshness of fruit in the grocer’s produce section, and it all starts with a small strip of coated fabric.
The research, published in the “Journal of Chromatography A,” showed the coated fabric can soak up the chemical compounds in the juice of an orange to show the ripeness – or freshness – of the fruit.
