Chennai Engg Grad Invents Simple Test to Check Authenticity of Organic Food!
But, are you sure that the food you are paying a hefty price for is actually organic? Hemalatha Rajendran, a BTech graduate from Chennai has a simple test for you to see whether your organic food is, in fact, organic, or is mixed with urea, pesticides or any other foreign ingredients.
Hemalatha’s father, an MTC (Metropolitan Transport Corporation) driver, had wished for his daughter to utilize her education to develop something that could be of use to the common man. Taking her father’s advice and applying her knowledge about biotechnology, Hemalatha developed an apparatus that can easily show any user whether the food on their table is infused with chemicals or not. Hemalatha developed strips of A4 sheets, like a litmus paper that could be dipped in milk and a change of color would indicate the impurities in it. She dipped the A4 sheets in a reagent that she discovered while working on a pesticide detection tool. “The reagents I used are the ones labs generally use to detect urea or pesticide,” she told the publication.
