Food adulteration has become very common now and it is one of the main problem to the public health. The recent controversy regarding the high content of lead in Maggi that is manufactured by Nestle has forced revision of safety laws of food and adoption of some strict law. The technology has made so much advancement that it has become difficult to find adulterants in the products that we use in our day-to-day life. It looks so similar to the natural foods that it becomes difficult to detect it. Here are a few tips that can help you in checking adulterated food at home:
You can add a drop of iodine to a few drops of milk. If the milk turns blue, it contains starch that can make it thick and rich in texture.
Take a test- tube and add small amount of ghee or butter in it. You can now heat it up. Now add a small amount of sugar and dissolve it in a solution of 10 ml hydrochloric acid. Add this solution to butter and ghee. If the mixture turns red, it means that ghee or butter is adulterated.
• Mustard oil:
Take very little mustard oil in a test-tube and add nitric acid to it. Now Shake the mixture and heat it for 2-3 minutes. If it turns red, it means that argemone oil has been added in the mustard oil.
