Are your veggies fresh or fake? A detailed guide to identify artificially coloured vegetables

From soft, tender spinach to crisp, refreshing cucumber, we often think we are buying the best and freshest vegetables from the local trusted vendor. But have you ever thought about who will guarantee if the veggies are actually fresh and not chemically treated or grown artificially? A shocking video from March 2023, has resurfaced on X (previously Twitter) and has once again raised the question about the quality of vegetables we eat and how safe they are for the human brain and body? According to the 1.42 minutes video, shared by Amit Thadhani, a surgeon and trekker, leafy greens are soaked in a foamy chemical solution for a few seconds. They are then kept to rest on a crate and within a few seconds, they change colour and the shrunken leaves broaden and appear fresh out of the farm. The viral video has garnered over 1 million views and 250+ comments.According to the Food Safety and Standards Authority of India (FSSAI), use of colours on fruits and vegetables are not permitted under the provisions prescribed in sub regulations 2.3.6 of Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations, 2011.According to experts, bright green vegetables are more visually appealing and can fetch a higher price in the market and that is why vendors soak or wash veggies in the chemical solution. However, these artificial enhancements can involve harmful chemicals, which may have adverse effects on health, including allergies, gastrointestinal issues, and long-term complications like organ damage.Artificial dyes and colours often contain harmful chemicals, such as malachite green or copper sulfate, rhodamine B and even Sudan dyes; all these chemicals are not safe for consumption. These chemicals can cause allergic reactions, especially in children and sensitive individuals. They can even lead to digestive issues like nausea, vomiting, and abdominal pain. According to experts, prolonged exposure can contribute to long-term health problems, including liver and kidney damage.Malachite Green: They are mostly used on green vegetables like peas or leafy greens to enhance colourMetanil Yellow : This chemical is added to turmeric or occasionally vegetables to intensify yellow tonesRhodamine B: This one is used to give a bright pink/red hueSudan dyes: These are oil-soluble dyes sometimes misused to deepen red/orange colour and are carcinogenicCopper sulfate solutions: These are occasionally used to make greens look brighter and fresher (can be toxic in excess).Signs of artificially colored vegetablesUnnatural brightness: If the vegetable looks overly bright or fluorescent greens, it indicates artificial coloring. Naturally fresh vegetables have a vibrant but natural green shade and are best for the human body.Color residue: Always rub a small part of the leaf or skin gently with your fingers or a damp cloth. If the color comes off, it’s likely that the vegetable has been artificially colored.Uniformity in color: If the vegetable is in single tone and you can't observe any variation in colour throughout the body of the vegetable, then it's a sign of artificial coloring. Real vegetables have slight variations in shade due to natural growth and exposure to sunlight.Water test: After buying, always immerse the vegetables in salt water for a few minutes. If the water turns green, it’s a sign of artificial dye. Never hesitate to confront the vendor about this and avoid such veggies at all costs.Buy from trusted sources: While this is quite a cliche, it is the only way to avoid falling prey to cheating vendors. It is best to shop from farmers' markets or organic stores, where the likelihood of tampering is lower.Inspect thoroughly: Never buy veggies in a rush. Always look for natural signs of freshness, such as firm stems, crisp leaves, and a natural earthy smell. And always avoid vegetables with an excessively glossy or waxy appearance.Wash thoroughly: After buying the veggies, wash them thoroughly under running water and also use warm salt water to remove all extra dirt and chemicals. It is also suggested to remove the peel of veggie (where possible) and then cook them.Images Courtesy: istock
