Watermelon is the ultimate summer fruit— sweet, juicy, and refreshing. But did you know some vendors use dangerous chemicals and artificial colors to make watermelons look redder, sweeter, or riper than they really are?
In this quick guide, we’ll show you how to identify adulterated watermelon at home in just 3 easy steps — plus a bonus cotton ball test that’s super simple and effective.
Why Adulterated Watermelon Is a Health Risk?
Many watermelons are treated with:
Red dye like erythrosine to fake ripeness.
Sugar or glucose solution to boost sweetness.
Calcium carbide or ethylene spray for early ripening.
These adulterants can cause food poisoning, stomach upset, allergic reactions, and even long-term organ damage.
Table: Watermelon Adulterants & Simple Home Tests
Adulterant | Signs to Watch For | Simple Home Test |
Artificial Red Dye (Erythrosine) | Over-bright red flesh, glossy look | Water test – Flesh turns water red |
Chemical Ripening Agents | Bitter taste, overly firm or rubbery feel | Taste check – Unnatural flavor, no aroma |
Glucose Injection | Extra-sweet taste | Taste check – Sticky or syrupy flavor |
Dye on Surface | Slight red residue on hands when touched | Cotton ball test – Red color transfer |
3 Easy Tests to Identify Adulterated Watermelon
1. 🔍 Visual Check
Cut the watermelon and inspect it.
Too bright or uniform red? Could be artificial dye.
White patches or cracks? May indicate chemical ripening.
Sticky or slimy flesh? Avoid it.
2. 💧 Water Test
A classic test to catch color adulteration.
How to do it:Drop a small chunk of watermelon flesh into a glass of clean water.
❌ If water turns reddish, it’s likely colored artificially.
✅ If water stays clear, you’re safe!
3. 👅 Taste & Texture Check
Take a small bite:
❌ If it tastes too sweet, chemical or syrupy — avoid.
❌ Bitter or sour? Could be chemically ripened.
✅ A good watermelon is juicy, lightly sweet, and naturally aromatic.
FSSAI Approved Bonus Test: Cotton Ball Test for External Dyes
If the outer skin looks polished or unusually red, try this:
How to do it: Rub a moist cotton ball on the watermelon surface.
❌ If the cotton turns pink or red, it’s artificially colored.
✅ No color change? You’re good to go.
If you don't have a cotton ball , you can use:
1. tissue paper
2. toilet paper
3. any plain piece of paper.
🍉 How to Choose Safe Watermelon When Buying

Don’t buy those that look unnaturally shiny or overly red.
Always buy from your trusted local vendor or hypermarket.
Do the above mentioned tests before consuming .
Tip: Natural watermelon has a mix of red and pink tones, not one flat shade.
