How to spot real and fake watermelon: Simple home tests to do amid FSSAI findings of adulterated fruits in markets

With summer in full swing, watermelon has become a go-to fruit for hydration and cooling relief. However, concerns over adulterated fruits in the market have been rising, with food safety authorities like the Food Safety and Standards Authority of India (FSSAI) warning consumers about artificially ripened and chemically injected fruits. Among these, watermelon is one of the most commonly tampered fruits, making it important to know how to identify real and fake watermelon at home.

Eating chemically treated watermelon can pose health risks, especially for children and the elderly. So before you slice into that bright red fruit, here are some simple, effective ways to check if your watermelon is safe and natural.

Why Fake or Adulterated Watermelons Are a Concern

To meet growing demand and improve appearance, some sellers resort to unsafe practices such as injecting chemicals or artificial colours into watermelons. Substances like erythrosine (a red dye) or other harmful agents may be used to enhance the fruit’s colour, making it appear fresher and sweeter than it actually is.


These chemicals can lead to digestive issues, food poisoning, or long-term health problems if consumed regularly. That’s why knowing how to identify a natural watermelon is crucial for safe consumption.

Check the Colour Inside the Watermelon

• One of the easiest ways to spot a fake watermelon is by observing its inner colour.
• A natural watermelon has a slightly uneven red or pink shade with visible fibres.
• A fake or chemically treated watermelon may appear unnaturally bright red, almost glowing, with little to no variation in colour.
• If the colour looks too perfect or artificial, it’s worth being cautious.

Tissue Paper Test for Artificial Colour

This is one of the simplest home tests recommended for detecting adulteration.

• Cut a small piece of the watermelon.
• Take a clean white tissue or cotton ball and rub it gently on the pulp.

If the tissue turns red or pink, it could indicate the presence of added artificial colour. Natural watermelon juice should not leave strong stains like synthetic dyes.

Check for Cracks and Texture

The texture of the watermelon can also reveal a lot.

• A natural watermelon has a firm yet slightly grainy texture.
• A fake one may feel overly soft, mushy, or watery inside.

Also, look for unusual cracks or separation in the flesh, which could be a sign of chemical interference.

Taste Test Matters

While visual checks are helpful, taste is another important indicator.

• Real watermelon has a mildly sweet, refreshing flavour.
• Fake or chemically treated watermelon may taste overly sweet, bland, or slightly bitter.

If the taste feels off or unnatural, it’s best not to consume it.

Look at the Seeds

Seeds can also help identify whether the fruit is natural.

• Natural watermelon seeds are usually dark brown or black and well-formed.
• If the seeds appear unusually pale, underdeveloped, or inconsistent, it may indicate tampering or artificial ripening.

Check the Outer Appearance

Before buying, always examine the outer skin of the watermelon.

• A natural watermelon typically has a dull, uniform green surface with a yellow spot (field spot) where it rested on the ground.
• An overly shiny or perfectly polished surface may indicate chemical treatment.
• The yellow patch is actually a good sign, showing that the fruit ripened naturally in the field.

Water Test for Juice Leakage

Another quick test you can try at home:

• Drop a small piece of watermelon into a glass of water.
• If the water turns red quickly, it could suggest the presence of artificial colour. Natural watermelon juice does not dissolve rapidly or change the water’s colour so intensely.

Avoid Pre-Cut Watermelons

Pre-cut fruits sold in open markets may be more prone to contamination or chemical exposure. It’s always safer to:

• Buy a whole watermelon
• Wash it thoroughly before cutting
• Store it properly in the refrigerator

FSSAI Guidelines on Food Safety

FSSAI has repeatedly warned consumers about adulteration in fruits, especially during peak summer months. The authority advises people to:

• Buy fruits from trusted vendors
• Avoid overly bright or unnatural-looking produce
• Wash fruits thoroughly before consumption
• Stay informed about common adulteration practices

Being aware and cautious is the first step towards ensuring food safety.

Health Risks of Eating Adulterated Watermelon

Consuming chemically treated watermelon can lead to several health issues, including:

• Stomach pain and digestive problems
• Nausea or vomiting
• Allergic reactions
• Long-term toxicity from chemical exposure

Children, pregnant women, and older adults are particularly vulnerable, making it even more important to ensure the fruit is safe.

Watermelon is one of the healthiest and most refreshing fruits you can enjoy during summer, but only if it’s natural and free from harmful chemicals. With increasing cases of fruit adulteration, taking a few extra minutes to check your watermelon can go a long way in protecting your health.

By following these simple tips, from checking colour and texture to performing easy home tests, you can confidently identify real vs fake watermelon and enjoy a safer, healthier summer.

Stay alert, buy wisely, and make food safety a priority.
