Spotting Synthetic Colors
During a recent 'Eat Right Mela' in Hyderabad, the Telangana Food Safety Department hosted interactive displays that enlightened visitors about prevalent
food adulteration. One key focus was on the deceptive use of artificial coloring agents in various food products. Attendees were shown examples of items like sweet potatoes with unnaturally vibrant skins, intensely colored dried kiwi slices, artificially green peas, and multi-hued confectionery. The objective was to illustrate how manufacturers might employ non-permitted colorants to make products appear more appealing, thereby potentially misleading consumers. The department emphasized that while sophisticated laboratory analysis is the definitive method for detecting such adulteration, simple visual inspection can serve as an initial warning sign for discerning consumers. Observing colors that seem excessively bright, unnaturally uniform, or far too vibrant for the natural product—such as peas that gleam with a fluorescent green or intensely orange-hued dried fruits—can indicate the presence of synthetic dyes. Furthermore, if a color rubs off onto fingers or washes away easily, it strongly suggests artificial coloring has been used.
Dairy Product Integrity
The second crucial area addressed by the Telangana Food Safety Department's demonstrations concerned the adulteration of milk and other dairy products, items frequently subjected to tampering due to their high demand. Officials showcased a straightforward method to detect the presence of starch in milk by adding a few drops of iodine solution. If starch is present, the mixture will turn a distinct blue-black color, signaling an adulterant. Beyond milk, the stalls also provided insights into identifying impurities in ghee and butter. These methods often involve observing subtle changes in texture, aroma, or how the product reacts when exposed to heat or specific chemical agents. Visitors also learned to identify diluted milk by observing its consistency and the distinct layering that occurs when it is left undisturbed. These practical demonstrations, utilizing simple tools like droppers, aimed to equip attendees with the knowledge to perform basic checks at home. The department underscored the importance of this consumer awareness as a primary defense against food fraud, complementing formal laboratory testing.
