In India, where tea has long been the preferred beverage, coffee is quickly becoming more and more popular, and its strong flavour, aroma and energising qualities are liked by people, particularly among the younger population. However, several adulteration techniques have also been seen because of the growing demand for coffee, lowering its quality.
To boost their profit margins, dishonest manufacturers may choose to incorporate clay and other materials into coffee powder due to the growing price of coffee beans. This technique could also harm consumer health. The significance of guaranteeing purity in coffee has been acknowledged by the Food Safety and Standards Authority of India (FSSAI), which has made basic water test techniques available to consumers so they can identify adulteration at home.
Coffee Adulteration
There are several ways that coffee can be adulterated, but one of the most common additions to poor coffee powder is clay. Artificial colouring agents, chicory, and starch are examples of other prevalent adulterants. But most of these compounds also reduce coffee’s flavour and aroma and, ingested in excess, may pose health hazards. The quality of the overall coffee can be badly affected by adulterants. For example, clay changes the coffee powder's texture and appearance, giving it a denser, darker appearance than pure coffee.
Detection Method
Materials Needed
- A transparent glass
- Clean water
- ½ teaspoon of coffee powder
Take ½ teaspoon of the coffee powder you want to test in a clear glass. Pour clean, room-temperature water into the glass until it is approximately three-quarters full. To make sure the coffee powder is completely dissolved in the water, give the mixture a good stir for approximately one minute. After five minutes of letting the mixture sit undisturbed, carefully check the bottom of the glass.
There should be very little to no sediment at the bottom of the glass if the coffee is pure. The coffee should dissolve and leave the water clear or slightly tinted. Sediment will settle at the bottom of the glass if there is clay or another adulterant present. The presence of this sediment indicates that there has been adulterants in your coffee powder.
Precaution
Today's consumers must know about food adulteration. If people can identify adulterants such as clay in coffee, they will be able to make informed choices about what they eat. Besides water tests, consumers should take extra precautions to make sure they are buying high-quality coffee. A convenient way is to purchase coffee from reliable brands and well-known suppliers.
Reading reviews and suggestions allows you to know more about the quality of the product you are considering. It also helps to learn about the coffee’s origin and processing techniques. Since organic and single-origin coffees typically come from regulated sources that place a premium on quality, they are frequently less likely to be tampered with.
