Sweet potatoes, a beloved winter staple in Indian households, are celebrated for their natural sweetness, softness, and health benefits, including being rich in fiber, vitamins, and antioxidants. However, a growing concern is the prevalence of fake or chemically treated sweet potatoes in the market. Retailers often apply artificial colors, wax, or chemical solutions to older produce to make them appear fresh and appealing. Consuming these chemically treated vegetables can lead to various health issues such as nausea, vomiting, diarrhea, skin allergies, and respiratory problems.The article provides practical, lab-free home tests to help consumers identify pure sweet potatoes. First, rubbing the skin with fingers or a wet cloth can reveal artificial dyes if color transfers. Second, scratching the surface with a nail should expose natural flesh; any coating, wax, or powder indicates chemical treatment. Third, soaking a piece in water for ten minutes will result in colored or cloudy water if chemicals are present. Additionally, natural sweet potatoes possess an earthy, soft scent, whereas a strong chemical smell is a red flag. Lastly, genuine sweet potatoes are not cloddy, sticky, or excessively shiny, as 'too glossy' often suggests wax polish. By employing these simple tests, families can safeguard their health, ensuring they reap the genuine benefits of this nutritious root vegetable, which include boosting immunity, aiding digestion, and managing blood sugar.
