How to detect artificial ripening of fruits
A group of researchers led by the head of the food science and technology department of Pondicherry University said that they have developed a simple, fast and cost-effective method to detect artificial ripening of fruits by calcium carbide. Consumption of fruits ripened artificially using calcium carbide may cause serious health hazards. The team, led by Prathap Kumar Shetty, developed a sensor solution (bio-functionalized gold nanoparticle). When the solution is mixed…
