How to Detect Artificial Color in Watermelon: A Complete Guide
Watermelon is a refreshing summer fruit, but some sellers may inject artificial dyes to enhance its red color. These chemicals, such as Erythrosine (Red No. 3), can pose health risks. In this blog, we’ll explore simple ways to detect artificial color in watermelon and ensure you consume only natural, safe fruit.
Why Do Some Sellers Add Artificial Color to Watermelons?
The bright red color of a watermelon is a key indicator of ripeness. However, some unscrupulous vendors inject synthetic dyes to make unripe or pale watermelons look more appealing.
The Times of India has reported on the issue of artificial coloring in watermelons on multiple occasions. Notable articles include:

6 Easy Ways to Detect Artificial Color in Watermelon
1. Cotton Ball Test
This is a quick and effective way to check for artificial coloring.
Steps:
- Cut a piece of watermelon.
- Rub a cotton ball or tissue paper over the pulp.
- If the cotton ball turns red or pink, it’s likely artificially colored.
2. Water Test
Dyes dissolve in water, making this test a reliable method.
Steps:
- Take a small piece of watermelon and place it in a glass of water.
- Wait for 10–15 minutes.
- If the water turns pink or red, the watermelon may contain artificial color.
3. Visual Inspection
Look closely at the watermelon’s flesh and texture.
Signs of Artificial Coloring:
- Unnaturally bright red or pink color – A natural watermelon has a deep red or slightly pinkish hue, not an overly bright one.
- Uneven coloring – If some areas are significantly darker than others, the fruit might be artificially enhanced.
- Sticky or hard texture – If the pulp feels unusually hard or sticky, it may have been injected with chemicals.
4. Knife Test
When you cut a naturally ripe watermelon, the juice should be clear.
Warning Sign:
- If the knife blade turns red after cutting, the watermelon may be artificially colored.
5. Taste Test
Chemically treated watermelons may have an unusual taste.
Signs to Watch For:
- A bitter, chemical-like aftertaste instead of a fresh, natural sweetness.
- A lack of the typical juicy, refreshing flavor of a ripe watermelon.
6. Lab Testing (For Accuracy)
For professional verification, food safety labs use scientific methods to detect artificial dyes, such as:
- Chromatography – Identifies synthetic food dyes in fruit.
- Spectrophotometry – Measures dye absorption in light.
FSSAI Guidelines on Detecting Artificial Color in Watermelons
The Food Safety and Standards Authority of India (FSSAI) has developed guidelines to help consumers detect adulteration in watermelons. One such method involves testing for the presence of Erythrosine color, a synthetic dye. FSSAI provides a video demonstration of this test, which can be accessed here:
